As the number of plants increases, absorbing load fluctuations is becoming an important responsibility of thermal power plants. For this reason, a power generation plant is required that is capable of large load fluctuations such as shutting down at midnight and starting up in the morning, and that can maintain high thermal efficiency even at partial loads. A possible power generation plant that meets this requirement is a power generation plant in which multiple power generation units with small single output capacities are combined into one power generation unit for system operation.
