UNIVERSAL MICROGRID CLUSTER DISTRIBUTED CONTROL METHOD COMPRISING CONSTANT POWER AND DROOP CONTROL

WIPO Patent Application WO/2018/058804

A1

A universal microgrid cluster distributed control method comprising constant power and droop control, comprising the following steps: step 10) performing primary control, keeping the power of a microgrid cluster balanced; step 20) determining a predefined cluster consistency convergence value of a pinning proxy; step 30) proxies other than the pinning proxy seek for cluster consistency with the pinning proxy via communication coupling; and step 40) adjusting output power and completing secondary control. The control method employs stratified control and, based on pinning control, a distributed power cluster comprising two control schemes, namely constant power control and droop control, and is a distributed control method. The method obviates the need for a central controller and a complex communication topology, reduces the number of controllers, is adaptable to communication topology changes in a microgrid cluster, and satisfies the demand for plug-and-play distributed power supply.
