OUTPUT CONTROL DEVICE, POWER GENERATION SYSTEM, AND OUTPUT CONTROL METHOD

Title:

OUTPUT CONTROL DEVICE, POWER GENERATION SYSTEM, AND OUTPUT CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2020/213654

Kind Code:

A1

Abstract:

The present invention controls the total output of a plurality of power generation facilities so that a grid-connected contract capacity is not exceeded in spite of rapid changes in the amount of sunlight. A hybrid power generation system (100) has a grid-connected contract capacity set as an upper-limit value of a sum of supplied power at a grid-connected point (210). An output control device (110) is provided with: a rapid-change predicting unit (112B) which predicts the time of improvement of a state in which exposure of a module (140) to sunlight is hindered; and an output determining unit (112C) which suppresses an output from a second power generation facility (P2) prior to the timing.
