“…Solar energy, with its availability, cost-effectiveness, accessibility, capacity, and efficiency, is the best option for meeting future energy demands. With the popularization of solar photovoltaic power generation technology, solar energy has been unanimously recognized and praised by the public [4][5][6][7]. The ongoing penetration of variable and intermittent renewable energy sources (RES), such as wind and solar energy, imposes additional and more critical requirements on power systems' flexibility [8].…”

To address China’s small coal power units facing shutdown and retirement, which urgently need life cycle extension and renovation, a complete solar thermal storage simulation power generation system based on the original site of a decommissioned thermal power unit is developed using Ebsilon software in this study. The operational characteristics of the simulated system are studied in depth to build a system with integrity and stability that can carry out economic and stable power production. The results of simulation tests on the solar collector system and the thermal storage subsystem show that the energy storage rate of the energy storage subsystem is affected by light intensity and significantly increases at approximately 8:00 a.m. The annual power generation capacity of the system is influenced by the energy storage hours set by the energy storage subsystem, and the annual power generation capacity increases more significantly when the energy storage hours are controlled within the range of 5–8 h. The operating efficiency of the corresponding subsystem can be improved by selecting a suitable location for the light intensity required and controlling the effective reflectivity of the mirror field and the energy storage hours, which can ensure the system’s stable operation. The research results provide theoretical guidance for reusing and transforming retired thermal power units.
