Abstract

With the rapid promotion of renewable energy and the development of new power systems in China, it has become a priority to solve the imbalance between the load and renewable energy output power of integrated energy system (IES), and to improve the economy and flexibility by using energy storage and flexible load co-optimisation. Based on this, an IES model integrating renewable energy output power uncertainty model, flexible load model and energy storage device model is constructed. Finally, the model is solved using the commercial solver CPLEX. The simulation results show that the proposed IES model can effectively improve the operating economy of IES and its renewable energy consumption capacity, and provide a theoretical reference for the collaborative scheduling and unified planning of various energy sources.
