Abstract
A storage battery control apparatus includes: a storage battery state detection unit which obtains a remaining SOC which is an SOC of a storage battery at the start of a supply and demand control period; an offset power value determination unit which determines an offset power value that is a power value indicating charge or discharge; an adjustment instruction value obtainment unit which obtains an adjustment instruction value indicating a state of charge and discharge of the storage battery; and a charge and discharge control unit which performs control of discharging power from the storage battery to the grid or charging power from the grid to the storage battery, the power having a magnitude of a first power value which is a power value obtained by adding the offset power value to the adjustment instruction power value indicated by the adjustment instruction value.

16. A storage battery control apparatus for performing a frequency regulation service to a power system operator, the storage battery control apparatus comprising:
-
a communication interface configured to communicate with the power system operator; and a controller configured to; obtain information of state of charge (SOC) of the storage battery at a start of a supply and demand control period; determine an offset power value which is a power value for reducing a difference between the obtained SOC and a target SOC which is a target value of the SOC of the storage battery at an end of the supply and demand control period; receive an adjustment instruction power value for the frequency regulation service from the power system operator via the communication interface; generate a corrected instruction value by adding the offset power value to the adjustment instruction power value; and operate discharging, from the storage battery to a grid, power corresponding to the corrected instruction value, or charging, from the grid to the storage battery, power corresponding to the corrected instruction value. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 30)

29. A storage battery control method for performing a frequency regulation service to a power system operator, the storage battery control method comprising steps of:
-
obtaining information of state of charge (SOC) of the storage battery at a start of a supply and demand control period; determining an offset power value which is a power value for reducing a difference between the obtained SOC and a target SOC which is a target value of the SOC of the storage battery at an end of the supply and demand control period; receiving an adjustment instruction power value for the frequency regulation service from the power system operator a communication interface; generating a corrected instruction value by adding the offset power value to the adjustment instruction power value; and operating discharging, from the storage battery to a grid, power corresponding to the corrected instruction value, or charging, from the grid to the storage battery, power corresponding to the corrected instruction value.
