| Abstract: | Energy storage power station is an effective method to meet the urgent demand for solving the problem of intermittency and instability of renewable energy and improving the efficiency, security and economical efficiency of conventional electric power system and the regional energy system. A new kind of thermal storage power station technology----Independent thermal storage power station with molten salt is proposed in this paper. This paper outlines the principle, conceptual design and techno-economic appraisal of the independent thermal storage power station with molten salt. The results show that initial investment of the station is very low, only 6152.88yuan/kW. Its payback period is short, within three years. Independent storage plant with molten salt can set up in cities and towns with less area occupation and the plants can realize the cogeneration of heat and power. Total efficiency can be raised from 30% for power only to more than 80% for cogeneration. |
