Abstract
A power supply and demand control apparatus includes a power generation planning unit that calculates one day's power outputs of multiple distributed power sources and a power flow target of a linking point to another power system, a long-cycle control unit having a long-cycle supply-demand balancing control unit that performs control every few minutes so as to ensure the supply-demand balancing of electric energy in a given amount of time at the linking point in order to perform control for making deviations between total power output calculated by the power generation planning unit and load power in the power system constant, and a short-cycle control unit having a short-cycle supply-demand balancing control unit that performs similar control every few seconds. In the power supply and demand control apparatus, the long-cycle control unit and short-cycle control unit perform the supply-demand balancing control in a hierarchical fashion to determine output assignments of the distributed power sources.
