Optimal dispatch of multi-energy complementary integrated energy systems

Abstract

Integrated energy system is an effective way to realize multi-energy complementation in intelligent parks, but its system operation and scheduling is difficult to balance economy and environmental protection. For the optimization of the operation and control of the combined cooling, heating and power supply system, a comprehensive energy system has been established, including photovoltaic, wind power, gas turbines, chillers, waste heat and power. The economic dispatch optimization model for renewable energy sources such as recovery systems and energy storage devices, with the goal of minimizing economic operating costs, and comprehensive The fuel cost, power purchase and sale cost, carbon emission cost, etc. are considered and solved by the model prediction and control method. Finally, the actual smart park energy system is simulated and analyzed to verify the validity and feasibility of the established model, and the results show that based on the optimization method of model prediction and control can optimize the overall operating costs of the system and provide a preliminary stage for the planning of the integrated energy system of the park.
