Abstract: A control device including a power generation amount detector, a flow detecting unit which detects an amount of flow power and outputs the flow power amount as a flow signal, a flow control unit which compares a preset target value with the flow signal and outputs a flow operation amount, a power generation control unit which outputs an amount of generated power, an instantaneous power transmitter which detects instantaneous power and outputs the instantaneous power as an instantaneous power signal, a demand control unit which outputs a demand operation amount, and a setting value calculating unit which obtains a demand target value, outputs the demand operation amount according to the result of a comparison of the demand target value with the instantaneous power signal, and determines whether to change a setting value according to the amount of power being output from the power conditioner for power generation.
Abstract: The present invention is provided with: a power converter (14) connected to a power plant (12) for generating power from renewable energy and having a proportional-control type power adjusting function that outputs the power generated by the power plant (12) after converting a direct current into an alternating current, and that adjusts the outputted power proportionally to a manipulation level; an instantaneous power detector (3) that detects an instantaneous power of the power outputted from the power converter (14); a comparison unit (4) that compares the instantaneous power detected by the instantaneous power detector (3) and a target value set by a generated power setting unit (5) and outputs a comparison signal; a control unit (6) that adjusts the comparison signal outputted by the comparison unit (4); and an output signal unit (7) that outputs the comparison signal adjusted by the control unit (6) to the power converter (14) as the manipulation level.
