In recent decades, man's insatiable demand for energy has led to the indiscriminate consumption of fossil fuels, and the pollution caused by this consumption has led to global warming and environmental degradation. For this reason, human beings have turned to the use of renewable energy sources as an abundant, accessible and clean source. Meanwhile, the sun is a viable alternative to fossil fuels, which is expected to play a significant role in the Earth's energy future. In the present study, a solar power plant has been designed in 3 scenarios using simulation method with Fortran software. In the first scenario, the fluid is the cause of the solar cycle of molten salt, in the second scenario, the power plant is simulated using direct steam generation technology, and in the third scenario, water receives heat directly until it evaporates, and to superheat heat using solar salt as heat transfer fluid. In the following, for the superior storage system, the phase-change-material is designed as a cascade, which has 2 scenarios. In the first scenario, the operating fluid is the molten salt storage cycle, and in the second scenario, the operating fluid is water. The annual power output for molten salt systems, direct steam generation and the combined system of direct steam generation and molten salt were 337/327, 346/313 and 339/952 GWh, respectively, and the efficiency of the systems was 20%, 19/23%, 22/19%. The cost per kilowatt hour of electricity for these systems is $ 0.227, $ 0.216 and $ 0.221, respectively. The production capacity for energy storage systems for molten salt fluid and water flux was 506.679 GWh 507.310 GWh, respectively.
