Heat storage power generation system and power generation control system

A power generation control system configured to control a heat storage power generation system including:

• a heater configured to heat first heat transfer fluid;
• a heat storage including a heat storage material heated by the first heat transfer fluid, and configured to heat second heat transfer fluid with heat stored in the heat storage material;
• and
• a power generator configured to generate electric power by using the second heat transfer fluid,
• the power generation control system comprising:
• a heating controller configured to control heating of the first heat transfer fluid by the heater;
• and
• a power generation controller configured to control power generation performed by the power generator,
• wherein the heating controller controls the heating of the first heat transfer fluid based on a fourth limit value 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 heat transfer fluid, a third limit value related to internal temperature of the heat storage, and the fourth limit value related to a change rate of the internal temperature.
