Title:
POWER STABILIZATION SYSTEM AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/208292
Kind Code:
A1
Abstract:
[Problem] To suppress unwanted compensation control that is based on the fluctuation of power flow and prevent the grid frequency from deviating from a target range.
[Solution] A control device for a power stabilization system comprises: a frequency detection unit for detecting the grid frequency of an AC power grid as a frequency measurement value; a power flow detection unit for detecting the power flow of the AC power grid as a power flow measurement value; a frequency control unit for acquiring an amount of power used to compensate the fluctuation of the grid frequency as a frequency compensation amount on the basis of the frequency measurement value; a power flow control unit for acquiring a power amount compensating the fluctuation of the power flow as a power flow compensation amount on the basis of the power flow measurement value and the frequency compensation amount; and a power convertor control unit for controlling a power convertor which converts power absorbed or discharged between the AC power grid and a power storage device according to the frequency compensation amount and the power flow compensation amount.
