Abstract: As the scale of integrated energy system (IES) connected to the distribution network continues to expand, the influence of IES on the distribution network becomes more prominent. Therefore, there are limitations in planning methods that only consider the economy and reliability of IES. To solve this problem, this paper proposes a multi-objective optimization method of IES siting and equipment configuration considering the economy and reliability of distribution network. Firstly, considering the coupling interaction between IES and distribution network, the economy and reliability evaluation models of IES-distribution network combined system are constructed respectively. Then, based on the NSGA-Ⅱ (non-dominated sorting genetic agorithm Ⅱ) multi-objective optimization algorithm, the equipment capacity and access point location of IES are optimized with the objective of the economy and reliability of IES and distribution network respectively, and the optimal scheme under different planning scenarios is selected in Pareto solution set by utility function. Finally, an example is given to verify the effectiveness of the proposed method. Simulation results show that the proposed method can realize the cooperative optimization of IES and distribution network economy and reliability.
