Title:
蓄電池制御装置、蓄電池制御プログラム
Document Type and Number:
Japanese Patent JP7066948
Kind Code:
B2
Abstract:
To establish logic for estimating planned power by predicting changes in sunshine hours and load fluctuations when power received from a grid, power generated by renewable energy, and power discharged from storage batteries are used together, and achieve both peak cut collateral and avoidance of selling power to a commercial power system.SOLUTION: Each determination (determination A (S>Smin+U), determination B (Smin+U>S≤Smin), determination C (S≤Smin)) is reflected in a power storage battery remaining amount S measured value-planned power P characteristic diagram, and the planned power P is set by the current remaining amount S of a power storage battery 32. At this time, the basic power differs depending on the determination result (current power L': upper limit power P') in a load/upper limit power comparison determination unit 80. In order to eliminate the difference between the planned power (L' or P') when there is a margin and the planned power (P=0) when there is no margin, the proportional control is performed (hunting prevention) in the power storage battery remaining amount S measured value-planned power P characteristic diagram.SELECTED DRAWING: Figure 7
