Title: POWER CONTROL DEVICE, POWER CONTROL SYSTEM, POWER CONTROL METHOD, AND PROGRAM
Abstract:
The present invention addresses the problem of optimizing a storage schedule for which the change over time in power (W) stored in an energy storage device is set, and optimizing the output upper limit value (W) of a renewable energy power supply. To overcome the problem, the present invention provides a power control device (10) for storing in an energy storage device a portion of the power (W) generated by a power generating device that exceeds an output upper limit command value (W), which is set by an electric power utility, wherein the power control device (10) has a determining unit (11) that, on the basis of forecast data for the change over time in the power (W) generated by the power generating device within a prescribed period, and on the basis of the value of various types of power divided on the basis of the output upper limit command value (W) within the prescribed period, determines a storage schedule in which the change over time in the power (W) stored in the energy storage device within the prescribed period is set.
