Title:
RENEWABLE ENERGY POWER GENERATION AND STORAGE CONTROL DEVICE FOR REVERSE FLOW PREVENTION TYPE SELF-CONSUMPTION
Document Type and Number:
WIPO Patent Application WO/2019/203211
Kind Code:
A1
Abstract:
This control device is provided with: a power generation amount detector (113) which detects an amount of power output from a power conditioner for power generation (112), as a power generation amount signal; a flow detecting unit (10) which detects a flow power amount and outputs the result as a flow signal; a flow control unit (20) which compares a preset target value with the flow signal and outputs a flow manipulated variable; a power generation control unit (30) which outputs, as a power generation manipulated variable, an amount of generated power obtained by comparing a power generation target value set on the basis of the flow manipulated variable with the power generation amount signal, to control the amount of generated power; an instantaneous power transmitter (91) which detects instantaneous power and outputs the result as an instantaneous power signal; a demand control unit (80) which outputs a demand manipulated variable only to a load capable of automated power control; and a setting value calculating unit (70) which obtains a demand target value, outputs the demand manipulated variable in accordance with the result of a comparison between the demand target value and the instantaneous power signal, and determines whether to change a setting value in accordance with the amount of power output from the power conditioner for power generation (112).
