Multi-objective Optimal Scheduling of Integrated Energy System Considering Energy Efficiency

To improve the energy utilization efficiency of an integrated energy system(IES),a multi-objective optimiza?tion model and its solving method are proposed considering energy efficiency.First,the factors affecting the efficiency of the energy flow link in IES are analyzed.Then,an economical objective function is established with the objective of minimizing the operating cost,and an energy efficiency objective function is established with the objective of optimizing the energy utilization efficiency.Moreover,the weighting coefficient method is used to transform the multi-objective op?timization into single-objective optimization.Finally,the model predictive control is used for optimal scheduling,and multiple scenarios are set up where single-and multi-objective optimizations are taken into account.The result of an ex?ample shows that the established model can guide the IES to make a rational utilization of energy and improve its energy utilization efficiency through the optimal scheduling of economic and energy efficiency objectives.
