Abstract:
1. A power generation system comprising: a power generation apparatus that generates electric power; a power control apparatus that outputs the electric power generated by the power generation apparatus to a power system; and a notification unit that provides the power system with information relating to estimation of an amount of electric power output from the power control apparatus, wherein the power control apparatus comprises: a power converter that converts the electric power; a power storage that stores the electric power output from the power generation apparatus or output from the power converter as well as discharges the stored electric power as necessary; a detection unit that detects an amount of the electric power generated by the power generation apparatus within a predetermined time period; and a control unit that sets an output pattern of the power control apparatus in a next predetermined time period based on the amount of generated electric power of each predetermined time period to match an amount of electric power output from the power control apparatus within the next predetermined time period with the amount of the generated electric power of each predetermined time period, and controls the output of the power control apparatus in accordance with the output pattern, wherein the control unit sets the output pattern by calculating an average value of the amount of the generated electric power of each predetermined time period, and sets the average value as an input target value for the power converter for the next predetermined time period, and wherein the notification unit estimates the amount of electric power output from the power control apparatus in the next predetermined time period based on the output pattern to provide the information relating to the estimation.
