摘要：
Aiming at the problem that energy storage improves system reliability and reduces operation economy，a two-stage optimization configuration method of energy storage is proposed，which comprehensively considers the reliability and operation economy of distribution network. Based on the power supply reliability model of a single main power supply，the power supply reliability models of energy storage with single point access structure and multi-point access structure are established respectively. In the first stage，taking the model of energy system with the single point access structure as the planning object，a two-layer model of multi-objective planning and operation is established. The upper layer takes the minimum sum of energy storage capacity investment cost，system safety cost and operation cost under a unified time scale as the optimization goal，and the lower layer takes the minimum sum of comprehensive operating costs as the optimization goal，taking into account the three operation costs of network loss，power quality and load fluctuation. And the planned operation scheme of energy storage is solved by using the Gruobi toolkit. In the second stage，considering the model of energy storage multi-point access topology after the transformation of new power supply cables is considered and the new cable planning scheme is obtained with the goal of maximizing the efficiency of reliability improvement. Taking the modified IEEE 33-bus system as an example，the effectiveness of the proposed method is verified under different scenarios，and the influence of different power outage risk prices on the planning results is analyzed. © 2024 Electric Power Automation Equipment Press.
