    摘要: A control method for a wind turbine generator and storage battery unit connected to a power grid in parallel, includes calculating total active power and total reactive power, and switching between: a first mode in which the generator outputs turbine required active power and reactive power that can be outputted by the generator and the battery unit outputs battery required active power and battery required reactive power which correspond to a difference between the total active power and the turbine required active power and a difference between the total reactive power and the turbine required reactive power respectively; and a second mode in which the battery required active power is maintained and the battery required reactive power is reduced while the turbine reactive power is increased by an amount of the reduction of the battery required reactive power wherein apparent power exceeds a set battery unit apparent power.

    摘要: A voltage equalization device of a power storage device provided with battery packs in which a plurality of secondary cells are connected, power converters provided in association with the battery packs, and controllers that control the power converters, and in which the battery packs are connected in parallel via the individual power converters includes a decision portion and a voltage-adjusting portion. The decision portion obtains battery-pack information regarding the states of charge/discharge of the individual battery packs and decides, for each battery pack, whether or not to perform voltage adjustment on the basis of the battery-pack information. When the decision portion decides that the voltage adjustment is to be performed, the voltage-adjusting portion generates offset instructions for adjusting the states of charge/discharge and outputs the offset instructions to the controllers of the power converters associated with the battery packs.
