Power management control system for a storage battery-equipped natural energy power generation system

摘要

When power management processing is started (S101), it is determined whether setting of calculation of a power generation output upper limit target candidate value is automatic or manual (S102). When it is not automatic calculation, the power generation output upper limit target candidate value is inputted (S103), and in the case of automatic calculation, the power generation output upper limit target candidate value is calculated (S104). Next, the power generation output upper limit target candidate value and a generator rated output are compared, and it is determined whether the power generation output upper limit target candidate value generator rated output (S105). If the comparison result is YES, the power generation output upper limit target value is set so that the power generation output upper limit target value = the power generation output upper limit target candidate value (S106). Next, control of regulating generation power of a natural energy power generation apparatus is performed so that a power generation output value is close to the set power generation output upper limit target value (S107). Thereby, in a natural energy power generation system with a storage battery, a storage battery can be reduced in capacity.
