In recent years, with the maturity of molten salt energy storage technology, thermal storage systems have become a common component of CSP systems. The solar thermal power generation system with a thermal storage device converts a part of the solar energy into heat energy during the day and stores it in the thermal storage system, and uses it to generate electricity after the evening or when the power grid needs peak regulation to meet the requirements of the power grid, which can ensure a more stable power output. It is reliable and can be used as a supporting power source for new energy bases.

Solar thermal power generation (CSP), as a kind of renewable energy power generation, not only retains the characteristics of wind power and photovoltaic clean power generation, but also has certain flexibility, coordinating the relationship between the use of renewable energy power generation and the uncertainty of its output. contradiction.

The solar thermal power station is composed of concentrating heat collection, heat storage and power generation. The energy transfer between different subsystems is realized by heat transfer fluid. The basic principle of power generation is the same as that of conventional generator sets. The thermal cycle of the CSP station has better controllability and adjustment ability than ordinary thermal power generation, and can reach a ramping speed similar to that of the gas-fired unit. The unit of the CSP station can reach 16~20% PGN/min at the fastest. The fast ramping capability further enhances the schedulable feature.
Solar thermal power generation is a technology- and capital-intensive industry with a long industrial chain, involving many disciplines and complex systems; the investment of the project is greatly affected by the scale of installed capacity and heat storage time.
