Research on Reliability Evaluation of Power Generation System with Solar Thermal Power

The reliability assessment of hybrid power generation systems with new energy is of great significance for optimizing energy allocation. At present, most of the researches on reliability assessment focus on wind power, photovoltaics and their hybrid power generation, but there is little research on the reliability assessment of hybrid power generation systems including solar thermal power generation (STP). By expanding the reliability evaluation research of wind power and traditional wind power photovoltaic hybrid power generation systems, a reliability evaluation model including STP is established. Considering the operation characteristics of thermal storage devices in STP system, a sequential Monte Carlo evaluation framework is adopted and random production simulation is performed for two intermittent power generation modes (wind power and STP). Therefore, the credible capacities of STP system with and without heat storage are evaluated when accessed to the grid separately or under hybrid power generation state.
