Abstract
The present invention provides a storage-battery control devicecapable of enhancing economical efficiency by controlling charge state of a storage batteryso that surplus power generated by photovoltaic generation can be entirely charged into the storage batteryeven in a case where power cannot be sold to a system power supply. A storage-battery control deviceaccording to the present invention includes a load-power prediction deviceto predict load power, a PV-power prediction deviceto predict generated power by photovoltaic power generation, and a system controllerto obtain a predicted charge amount that is calculated by subtracting the generated power amount being a summation of the generated power in a prediction segmenthaving a start point set at a predetermined time, from the load power amount being a summation of the load power in the prediction segment, and when the predicted charge amount is positive, to control the charge state of a storage batteryat the start point so that the predicted charge amount can be charged in the prediction segment, wherein an end point of the prediction segmentis a time at which the generated power by photovoltaic power generation is predicted to become equal to the load power after reaching the maximum value of the generated power.
