Abstract

The Combined-Cycle Gas Turbine (CCGT) power plants are increasingly required to provide the service for balancing the load demand and power supply with the increase of the intermittent power generation from renewable energy sources. To ensure CCGT power plants to operate flexibly and efficiently, it is necessary to find the suitable strategy. This paper presents the feasibility of a CCGT power plant combined with the Thermal Energy Storage (TES) to improve the plant operation flexibility. The dynamic simulation models of a 420MW CCGT power plant and TES system are presented in this paper. The TES charging and discharging strategies are investigated. The simulation results show that TES charging or discharging processes provide the additional mechanisms for regulating the output power of the CCGT power plant.
