Study on Optimization of Comprehensive Energy System Planning Considering Energy Efficiency

As a typical smart energy system, the integrated energy system can promote the in-depth integration of source, grid, and load, and increase the utilization rate of renewable energy. Therefore, the evaluation indicators of the smart energy system should simultaneously reflect the core characteristics of low carbon and high efficiency. This paper takes maximizing the comprehensive energy efficiency level and improving the energy consumption economy as the optimization goals, and proposes a multi-objective planning optimization model for the integrated energy system. Under the constraints of the physical constraints of the equipment and the balance of cooling, heating and power, the energy consumption economy and comprehensive planning and optimization strategies for energy efficiency levels. The analysis of calculation examples shows that the optimal scheduling strategy proposed in this paper can comprehensively improve the cleanliness and efficiency of system energy consumption.
