摘要:
Power management device includes memory, classification portion, planning portion and indication portion. Classification portion classifies a change in monitoring power during a unit period with respect to each of buildings, stored in memory, into any one of kinds of electric power patterns. Planning portion determines pattern sets based on the kinds of electric power patterns, and determines control content for charging and discharging of electric storage apparatus with respect to each pattern set under condition of minimizing any one of amount of electric power to be received from power grid, compensation of amount of electric power to be received from power grid, and amount of carbon dioxide to be exhausted. Indication portion indicates control content corresponding to each of pattern sets determined by planning portion to electric storage apparatus of a building, which each pattern set conforms with, of the buildings.
