Abstract
In one embodiment, a heat storage power generation system includes a heater to heat first fluid, and a heat storage to be heated by the first fluid, and heat second fluid with heat stored in the heat storage. The system further includes a generator to generate electric power by using the second fluid, a heating controller to control heating of the first fluid by the heater, and a power generation controller to control power generation performed by the generator. The heating controller controls the heating of the first fluid, based on two or more limit values among a first limit value related to an amount of energy consumption by the heater, a second limit value related to temperature of the first fluid, a third limit value related to internal temperature of the heat storage, and a fourth limit value related to a change rate of the internal temperature.
