Abstract
A power receiving unit receives power generated by power generating units via a power system. A power information acquiring unit acquires first system power information showing the proportion of power generated by each power generating unit in a first period. An intensity database stores environmental loading intensities for each power generating unit. A charge load intensity calculator calculates a charge load intensity which is a weighted sum of the environmental loading intensity corresponding to each power generating unit based on the proportion of each power generating unit in the first system power information. A charge/discharge judging unit determines to charge a storage unit in a first period when the charge load intensity is less than a reference value, and not to charge the storage unit in the other cases. A charge/discharge controller charges the storage unit in the first period when determined to charge the storage unit.
