Power system stabilization system and method employing a rechargeable battery system

摘要

A power system stabilization system is provided between power generation equipment significantly fluctuating in output and a power system (3) required to maintain a predetermined voltage. In the power system stabilization system, a voltage detection device (51) and a current detection device (52) detect voltage and current, respectively, of the power system (3) and voltage and current thus detected are used to calculate a level of active power required and that of reactive power required which are referred to to provide charging and discharging from a rechargeable battery (10) to the power system via an A-D converter (40).
