POWER SYSTEM CONTROL INSTRUCTION DEVICE

WIPO Patent Application WO/2015/151143

A1

The purpose of the present invention is to create a control model capable of maintaining the voltage of a power system within an appropriate range regardless of the quality of communication between a control instruction device for calculating a control amount and a control device for executing a predetermined operation on the basis of the control amount. According to the present invention, a power system control instruction device that provides a control device for controlling a power system with a control instruction on the basis of a measured value transmitted from a sensor for measuring a state value of the power system is characterized by being provided with: a centralized control amount calculation unit that obtains, using the measured value of said sensor, a centralized control amount such that the system voltage meets a predetermined control purpose; a distributed control model creation unit that creates a distributed control model using said measured value and said centralized control amount; a distributed control model re-creation unit that determines whether a voltage deviation from said voltage appropriate range occurs or not when said control device performs control on the basis of said distributed control model, and that re-creates said distributed control model when said voltage deviation occurs; and a transmission unit for transmitting said re-created distributed control model to said control device.
