Title:
GRID CONTROLLER, GRID CONTROL SYSTEM AND GRID CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP2017011938
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a grid controller, a grid control system and a grid control program capable of preventing lack of load frequency adjustment power, by allocating demand unbalance power properly to a plurality of accumulator batteries.SOLUTION: A grid controller has a demand unbalance acquisition unit 110 for acquiring the demand unbalance power of a power system where a plurality of accumulator batteries 2 perform charge and discharge, a SOC acquisition unit 120 for acquiring the SOC of the plurality of accumulator batteries 2, respectively, and a distribution unit 130 for distributing both or one of charge power and discharge power to the plurality of accumulator batteries 2. The distribution unit 130 has a command value creation unit 131 for creating a command value of charge and discharge for each accumulator battery 2, so that the demand unbalance power is equal to the total value of variation in the charge power and discharge power of each accumulator battery 2, and the SOC of each accumulator battery 2 is equal.SELECTED DRAWING: Figure 1
