STORAGE BATTERY CONTROL DEVICE

摘要

The purpose of the present invention is to prevent a storage battery from being unnecessarily charged or discharged even when a charge command value and a discharge command value are present at the same time as power command values to charging and discharging units and to improve economic efficiency by suppressing the charging and discharging loss and the energy loss. A command value calculation unit (9) calculates first and second power command values on the basis of the measurement result of a power measurement unit (8) at a power supply line (2). A command value determination unit (10) receives the first and second power command values from the command value calculation unit (9) and determines whether these power command values are a charge command value or a discharge command value. If the command value determination unit (10) determines that one of the first and second power command values is the charge command value and the other is the discharge command value, a charging and discharging unit control unit (11) stops any one of the charging and discharging units (4, 6) and operates only the other one.
