BACKGROUND

[0001] The present disclosure relates to configurable extended communication interface devices for monitoring and control of distributed energy resources or other power system devices, and to methods and systems including or utilizing such devices. Distributed energy resources ("DERs"), such as solar, wind and combustion engine power generation apparatuses and systems, are increasingly being introduced in electrical power grids. The introduction of DERs into power grids typically involves the creation of microgrids, which are localized or localizable energy grids with control capability allowing them to disconnect from the traditional power grid and operate autonomously, semi-autonomously and/or in a coordinated fashion with. Inter-device communication in microgrid environments has created complex and challenging communication and control problems. Some efforts have been made to address these challenges such as the introduction of and use of standard-based communication protocols. Yet, many DERs and microgrid devices are not compatible with standard-based communication protocols and may also not be compatible communication protocols used by other DERs and microgrid devices. For example, DER controllers often communicate with microgrid controllers by way of different communication protocols and multiple types of communication channels. Other DERs have no ability to communicate with centralized controllers. As DERs continue to be added to the power grids and to existing microgrids, control and communication in such environments is becoming increasingly complex. There remain unmet needs including reducing DER installation complexity, simplifying data transfer in existing microgrids, and increasing power system responsiveness to faults and other grid conditions. For instance, DERs installed in a power system may not communicate with a centralized controller and thus cannot respond to faults detected by another controller. Furthermore, DERs not capable of communicating using standard based communication protocols require time-consuming configuration in order to communicate with other devices in a power system. Using multiple communication protocols to communicate within a single power system slows or prohibits data exchange and power system responsiveness to faults and other conditions within the power system. There is a significant need for the unique apparatuses, methods, systems and techniques disclosed herein.

[0008] With reference to Fig. I there is illustrated an exemplary power system 100 including an exemplary configurable extended interface device 130 coupled to a distributed energy resource (DER) controller 110. It shall be appreciated that the configurable extended interface device may be coupled to a variety of power system device controllers in a microgrid, including controllers for automatic switches, inverters, or other dumb microgrid devices, to name but a few examples. As further described herein, configurable extended interface device 130 is one example of a communication interface device which is extended in that it is able to extend the communication compatibility of devices such as a DER to which it is coupled and which is configurable in that it is able to modify or vary its compatibility and data mapping capabilities and properties in response to received information from or about the system environment in which it is implemented.

[0009] DER controller 110 is structured to control and monitor a DER. Some examples of distributed energy resources include photovoltaic energy sources, wind energy sources, energy storage systems, flywheels, and diesd generators, to name but a few examples. Controller 110 may include sensors or other types of measurement devices structured to measure electrical or physical characteristics of the DER such as output voltage, output current, or operational status.

[0010] Controller 110 includes a communication port structured to transmit and receive data. In certain embodiments, controller 110 includes an analog and digital type of input/output logic for communicating with external devices. The data transmitted between controller 110 and another power device may include device measurements and commands. For example, controller 110 may be structured to send measurements via an analog port and device status via a digital port

[0011] In certain embodiments, controller 110 includes an industrial communications logic structured to map data to an industrial communications protocol before communicating with external devices. Controller 110 is structured to transmit and receive analog and digital data using industrial communication protocols. The data transmitted between controller 110 and another power device may include device measurements and commands. Examples of industrial communication protocols include Modbus, Distributed Network Protocol (DNP3), Fieldbus, or other vendor defined communication protocols, to name but a few examples. [0012] DER controller 110 is structured to output data to other devices using a communication channel 120. In certain embodiments, communication channel 120 is bidirectional, allowing DER controller 110 to receive commands or data from another device. DER controller 110 may include one communication port or a plurality of communication ports to which communication channel 120 may be operatively coupled. For example, DER controller 110 may include a 16 pin serial port, a 32 pin serial port, or an Ethernet port, to name but a few examples.

[0013] Configurable extended interface device (CEID) 130 is structured to receive data from DER controller 110 by way of communication channel 120 using one of a multitude of communication protocols, map the received data to a standard communication protocol used by another device in a power system, and output the receive data to other devices in the power system. In certain embodiments, CEID 130 is structured to receive commands from another device of the power system, map the received commands to the communication protocol of communication channel 120, and output the received commands to DER controller 110.

[0014] CEID 130 includes a DER controller interface 131 operatively coupled to communication channel 120. Interface 131 may include a plurality of different types of ports such that CEID 130 may communicate with any DER controller. Interface 131 is structured to transfer data between DER controller 110 and interface 131 using any type of communication protocol, including analog or digital data I/O, industrial communication protocols, or a combination thereof.

[0015] CEID 130 includes a data mapping logic 135 structured to receive data from DER controller 110 in the form of the communication protocol used by communication channel 120. Using the received data, data mapping logic 13S maps the data with to standard based data structure. Data mapping logic 13S may also receive data from another power device and map the received data to the communication protocol used by DER controller 110. The standard data structure may include a plurality of common data types, including boolean, integer (intS, intl6, int32, int64, enum), unsigned integer (int8u, intlou, int32u, dbpos, quality), floating point (float32, float64), or raw character byte (visible string, unicoded string, octet string, timestamp). Data received by data mapping logic 135 which does not conform to the standard data structure is mapped to the common data types of the standard data structure. [0016] In certain embodiments, the data mapping logic 135 is structured to abstract the definition of data items by creating data objects and services independent of communication protocols. The abstracted data models define a standardized data structure for describing a power system that enables all controllers of the power system to exchange data using identical protocols. The abstracted definitions allow mapping of the data objects and services from one communication protocol to another. For example, data mapping logic 135 may map data using a data model including a plurality of logical nodes, each logical node being a grouping of data and associated services related to a power function. Within each logical node is one or more data objects conforming to a common data class. Mapping includes transforming the model information into an object defined by a communication protocol. In certain embodiments, data mapping logic 135 uses abstraction and mapping techniques compatible with the TEC 61850 standard.

[0017] Standard based peer to peer communication can enable the fast data exchange between DER controllers, management systems, and protective I EDS in the system. This enables operator to reduce response times to grid conditions such as unplanned islanding or internal faults.

[0018] Using semantics based standard information models simplifies integration of different DER controllers from different vendors and provides standard means for aggregating microgrid resource capabilities and generation/load balance at the point of microgrid

interconnect. In this way, multiple microgrids may be combined into a larger distribution system where a microgrid is represented as a single controllable entity. Additional grid services may be performed by DER controllers with new communication capabilities of the configurable extended interface devices, such as ancillary frequency regulation or Volt/VAR control.

[0019] The microgrid interface of CEED 130 includes a substation configuration description (SCD) parser 132 structured to transmit data about the power system to data mapping logic 135. An SCD storage device 180 is structured to transfer an SCD file to SCD parser 137 by way of a wired or wireless communication channel. SCD storage device 180 may transfer the SCD file to parser 137 by way of a dedicated port or by way of external device interface 139. A SCD file is a computer file in XML format created according to standard based schema. The SCD file may include a single line diagram, as well as communication network and IED information. Parser 137 parses the SCD file and retrieves information regarding external devices with which to exchange information, including the single line diagram, communication network information, external device information, logical device information, logical node information, data object information, data attribute information, component information, GOOSE control block information, and MMS control block information. Information from the SCD file is allocate to each function of data mapping logic 135. For example, parser 137 retrieves information regarding the GOOSE control block, allocates data in the data mapping logic 135, and maps date received from DER controller to a GOOSE communication protocol used by external device interface 139. DER controller 110 may be configured with predefined setting values and functions based on the SCD file. For example, parser 137 uses the SCD file to determine a circuit breaker status dataset should be received from another power device within the same microgrid. The SCD file is updated when the microgrid is restructured or the communication network is altered. In certain embodiments, the communication network model and single line diagram data can be provided in a common information model (CIM) format.

[0020] CEID 130 includes a microgrid interface including an external device interface 139 structured to communicate with an external device 150 using one of a set of standard communication protocols. COD 130 is operatively coupled to an external device 150 by way of a communication channel 240. In certain embodiments, CEID 130 is operatively coupled to a plurality of external devices by way of a plurality of communication channels.

[0021] In certain embodiments, the set of standard communication protocols use a standard information model generated using data abstraction and a configuration language. Using the set of standard communication protocols allow for real-time communication with self- description. It is important to note industrial protocols lack these features. For example, standard communication protocols such as GOOSE and SMV use a layer 2 communication data link which allows for real-time communication, as opposed to DNP3 or Modbus which require TCP/IP.

[0022] In certain embodiments, one standard communication protocol is structured to transfer time stamped state information between data objects of the data model. In certain embodiments, one standard communication protocol is structured to transmit real-time data in an XML format. In certain embodiments, one standard communication protocol is structured to transfer time stamped sample measured values. [0023] External device 15O is a power system device configured to communicate with other power system devices using a standard communication protocol. In certain embodiments, external device 15O is a distributed energy resource management system (DERMS), a distribution management system (DMS), a relay, another CEID, a microgrid controller, or any other microgrid device configured to communicate in a standard communication protocol.

[0024] In certain embodiments, interface 139 is structured to communicate with external device ISO using communication protocols defined by IEC 6I8S0, such as IEC 61850-7-420 and l£C 61850-90-7. These communication protocols include generic object-oriented substation event (GOOSE), manufacturing message specification (MMS), sampled measured values (SMV), and Extensible Messaging and Presence Protocol (XMPP).

[0025] In the illustrated embodiment, CEID 130 includes an internal applications logic

133 structured to execute algorithms using data received by CEID 130 from DER. controller 110 or external device ISO. For example, logic 133 may receive circuit breaker statuses for all breakers within a zone of a microgrid from an Information Communication and Technology network, and determine whether the microgrid is operating in grid connected mode or islanded mode. In another example, internal applications logic 133 may receive multiple sampled measurement value streams from several external devices in a microgrid and determine issues with sensors, detect data spoofing, or detect a cyber-attack. In still another example, logic 133 may receive sampled values from an AC grid connection point and calculate both non-directional and direction overcurrent protections for backup protection. Logic 133 could also calculate a fault indicator of the microgrid or determine desired fault ride through characteristics, such as the characteristics defined by IEEE 1547-2017.

[0026] Analysi s generated by logic 133 may be available for other devices of the power system. For example, calculated fault indicators may be sent to a microgrid controller for fault cause determination, fault location and microgrid restoration processes.

[0027] The microgrid interface of CEID 130 includes a time synchronization logic 138 structured to communicate with an external timing device 160 by way of a communication channel 170. Logic 138 receives time data according to a standard protocol, such as pulse per second (PPSX Simple Network Time Protocol (SNTP), or IEEE 1588, to name but a few examples. Logic 138 receives the time data and synchronizes all data in CEID 130. For example, using time data. CEID 130 may determine whether incoming data from external device ISO is expired. External timing device 160 may be a GPS receiver that supports time protocols such as PPS, SNTP and IEEE 1588, to name but a few examples. It shall be appreciated that any or all of the foregoing features of CEID 130 may also be present in the other configurable extended interface devices disclosed herein, such as the CEIDs of microgrid 200 in Fig 2 and CEID 430 of Fig. 4.

[0028] With reference to Fig. 2 there is illustrated an exemplary microgrid 200 including exemplary configurable extended interface devices 217, 223, 203, and 223. It shall be appreciated that the topology of microgrid 200 is illustrated for the purpose of explanation and is not intended as a limitation of the present disclosure. For example, other microgrids may include a distributed microgrid control system including multiple microgrid controllers. Although microgrid 200 is illustrated with a single line diagram, microgrid 200 may be structured to transmit single phase or multiphase power.

[0029] Microgrid 200 is operatively coupled to a utility grid 201 and is structured to transmit power between microgrid 200 and utility grid 201 , Microgrid 200 includes a distribution network 203 coupled to a plurality of loads L 1-L8. Microgrid 200 also includes relays 233. 23S, 237, 239, and 241, each relay being structured to allow or disrupt the flow of electric current through a portion of distribution network 203. Microgrid 200 also includes a plurality of DERs and DER controllers coupled to distribution network 203 and structured to provide power to the loads L1-L8 of microgrid 204 and utility grid 201.

[0030] Each DER controller of microgrid 200 is coupled with a configurable extended interface device. Without the configurable extended interface device, significant effort is required to add a DER to a microgrid controls system. For instance, a microgrid operator may add a PV array with only Modbus communication protocol capabilities. In order to connect the new DER to existing DERMs or DMS, operators need to configure the Modbus communication protocol, including configuring an analog and digital points list and associating the measured or controlled quantities with the specific point in the list. The DMS or DERMS will need to poll for data at a specified polling rate. For example, the DMS or DERMs will poll for data every 5 seconds.

[0031] With configurable extended interface devices that support plug and play functions, DERs can connect with existing DERMS or DMS after setting up the internal mapping of the CEID. Each DER may be added to a semantically based model without the need for separate configuration for each DER. A semantic based model includes a plurality of objects in a model hierarchy, each object being specifically defined in the standard. Additionally, client- server model is supported by the standard based communication protocol, where data is reported whenever a changes occurs in a monitored quantity, eliminating the need to polling.

[0032] DER 209 is a diesel generator controlled by DER controller 207. A configurable extended interface device 205 is coupled to DER controller 207. Configurable extended interface device 20S is in communication with relay 233 and a microgrid controller 243. When a DER controller becomes able to communicate through standard based communication protocols using the configurable extended interface device, a system operator no longer needs to separately configure a communication channel between the DER controller and each power system device. By comparison, a microgrid may use a legacy protocol, such as Modbus or DNP3, to allow communication between two devices. The registers for analog measurements and control status differ for devices produced by different product groups require separate configuration in order for each DER controller to communicate with another device, such as microgrid controller 243.

[0033] DER 211 is a photovoltaic array and is coupled to a power converter 213 which is controlled by DER controller 215. A configurable extended interface device 217 is operatively coupled to DER controller 215. Configurable extended interface device 217 is in communication with relay 235 and microgrid controller 243.

[0034] DER 219 is a wind turbine controlled by DER controller 221. A configurable extended interface device 223 is coupled to controller 221. Configurable extended interface device 223 is in communication with relay 239 and microgrid controller 243.

[0035] DER 231 is and energy storage system and is coupled to power converter 229.

Power converter 229 is controlled by DER controller 227. A configurable extended interface device 225 is operatively coupled to controller 227. Configurable extended interface device 225 is in communication with relay 241 and microgrid controller 243.

[0036] Microgrid controller 243 is structured to use the standard based plug-and-play functionality, automatically detecting and monitoring DER controllers by communicating with the configurable extended interface devices. Microgrid controller 243 is also structured to monitor, analyze, and control the DERs of microgrid 200 using the configurable extended interface devices. In certain embodiments, microgrid controller 243 transmits commands to DER controllers through CEIDs so as to program schedules for DER production over a time horizon. [0037] DERs can advertise to controller 243 in an object model what capabilities they are able to provide in terms of power, energy, and ancillary services as well as operating conditions such as ramp rate and price. DERs may also use the standard based communication to request services, such as charging, based on grid state as published by system operator via CIM services. Using formal XML based description for DER asset capabilities provides a means for abstracting physical characteristics and specific details of a microgrid node, and expresses entity self- descriptions in a modeling language suitable for formal analysis and verification.

[0038] Implementing the configurable extended interface devices allows a system operator to have more control over microgrid 200 while reducing configuration time. For example, updating a standard based communication protocol in a microgrid with the

configurable extended interface devices merely requires updating the communication stack of each configurable extended interface device.

[0039] With reference to Fig. 3, there is illustrated a schematic block diagram of a computing device 300. Computing device 300 is one example of a DER controller or configurable extended interface device, which is used, in different embodiments, in connection with an exemplary power system, such as power system 100 shown in Fig. 1.

Computing device 300 may be a stand-alone device, an embedded system, or a plurality of devices structured to perform the functions described with respect to power system 100.

Furthermore, computing device 300 communicates with one or more external devices 310.

Input/output device 304 is comprised of hardware, software, and/or firmware. It is contemplated that input/output device 304 includes more than one of these adapters, credentials, or ports, such as a first port for receiving data and a second port for transmitting data.

[0041] External device 310 in different embodiments is any type of device that allows data to be input or output from computing device 300.

Furthermore, it is contemplated that external device 310 is be integrated into computing device 300. It is further contemplated that more than one external device is in communication with computing device 300.

Device 302 can further include multiple processors, Arithmetic-Logic Units (ALUs), Central Processing Units (CPUs), Digital Signal Processors (DSPs), Field-programmable Gate Array (FPGA), to name but a few examples. For forms of processing device 302 with multiple processing units, distributed, pipelined, or parallel processing can be used as appropriate. Processing device 302 may be dedicated to performance of just the operations described herein or may be utilized in one or more additional applications. In the illustrated form, processing device 302 is of a

programmable variety that executes processes and processes data in accordance with programming instructions (such as software or firmware) stored in memory device 306.

Alternatively, or additionally, programming instructions are at least partially defined by hardwired logic or other hardware. Processing device 302 can be comprised of one or more components of any type suitable to process the signals received from input/output device 304 or elsewhere, and provide desired output signals. Such components may include digital circuitry, analog circuitry, or a combination of both.

[0043] Memory device 306 in different embodiments is of one or more types, such as a solid-state variety, electromagnetic variety, optical variety, or a combination of these forms, to name but a few examples. Furthermore, memory device 306 can be volatile, nonvolatile, transitory, non-transitory or a combination of these types, and some or all of memory device 306 can be of a portable variety, such as a disk, tape, memory stick, cartridge, to name but a few examples. In addition, memory device 306 can store data or operating logic that is manipulated by processing device 302, such as data representative of signals received from or sent to input/output device 304 in addition to or in lieu of storing programming instructions, just to name one example. As shown in FIG. 3, memory device 306 may be included with processing device 302 or coupled to processing device 302, but need not be included with both. [0044] With reference to Fig. 4 there is illustrated a portion of an exemplary CEID 430 coupled to an inverter controller of a photovoltaic energy source, such as CEID 130 of Fig. 1. CEID 430 includes a data mapping logic 435 and an SCD parser 437. CEID is structured to receive data from an SCD file 480.

[0045] SCD file 480 includes data structure 481 structured to organize information including a microgrid single tine diagram (Microgrid Structure), communication information (Communication), and inverter component information. SCD parser 437 is structured to subscribe to SCD file 480 and extract necessary information. For example, CEID 430 needs measurements, switch statuses, and operation modes. Therefore, parser 437 extracts logical nodes MMXU1, CSWI1, XCBR1, and DOPM1 from SCD file 480. Each logical node is associated with data objects. For example, MMXU I is associated with TotW, TotVAr, Hz, and PhV. Data mapping logic 435 receives the extracted data models including the logical nodes and data objects, and maps the extracted data model to the data received from a DER controller, such as DER controller 110.
