Research on Operational Optimization Technology of Regional Integrated Energy System Considering Operating Cost and Reliability

To solve the problem of operation optimization for regional integrated energy system, a kind of operation optimization method considering operating cost and reliability is proposed. Firstly, the difference between multi-objective integrated energy system and traditional dispatching is analyzed. A multi-objective operation optimization framework of integrated energy system is introduced. Secondly, the output characteristics of the main integrated energy system equipment are analyzed. Thirdly, the objective function with the lower operating cost and the higher reliability is established. Then, taking into account the system constraints of electricity, heating and cooling, the multi-objective running optimization model is solved by linear programming method. Finally, an integrated energy system scene with distributed generation and energy storage equipment is constructed. The Pareto solution set of the scene is searched. Meanwhile, the different operating modes of CCHP are compared. The results show that the proposed model can meet the requirements and provide a unified optimization solution for integrated energy system.
