Abstract:Multi-energy complementary project of wind-solar-thermal integration can play a coordinating and mutually beneficial role among different generations, and is one of the implementation paths for safe and efficient use of renewable energy, and achieving carbon neutrality and carbon peak. How to reasonably match the installed capacity of thermal power, wind power, photovoltaic power and the transmission capacity, to ensure the full consumption and efficient utilization of wind power and photovoltaic power, is the core issue of the multi-energy complementary project of wind-solar-thermal integration. Based on the analysis of the output characteristics and multi-energy complementary characteristics of different generations, an optimal allocation model of multi-energy complementary project of wind-solar-thermal integration was constructed with the objective of minimizing the total cost and maximizing the matching degree between the sending curve and the receiving load curve. The installed capacity of wind power, photovoltaic power and the transmission capacity were optimized at the planning level, and the thermal power operation mode, output curve and transmission curve were optimized at the operation level. According to the case analysis, the optimal allocation model can optimize and determine the installed capacity of wind power, photovoltaic power and the transmission capacity, so that different generations can coordinate with each other on monthly and daily time scales. The transmission curve is more friendly to the receiving-end grid, and the horizontal multi-energy complementary and longitudinal generation-load coordination are realized.
