Abstract

In the planning of energy storage system (ESS) in distribution network with high photovoltaic penetration, in order to fully tap the regulation ability of distributed energy storage and achieve economic and stable operation of the distribution network, a two-layer planning method of distributed energy storage multi-point layout is proposed. Combining with the operation characteristic model of energy storage battery (ESB), a multi-point energy storage collaborative operation strategy considering the service life of ESB is proposed. A planning-operation two-layer model is constructed, in which the outer layer considers the total cost of ESS planning to determine the layout point number and capacity of ESS, and the inner layer focuses on the utilization rate of ESB and the operation stability of distribution network. The hybrid particle swarm optimization and non-dominated sorting genetic algorithm is used to solve the planning and operation results of distributed energy storage multi-point layout. Example analysis shows that after configuring a multi-point layout ESS, the total planning cost decreases by 20.25%, the utilization rate of ESB increases to over 50%, and the voltage fluctuation and loss rate of the distribution network decrease by 19.09% and 11.76%, respectively.

高光伏渗透率配电网络中多点布局分布式储能的双层规划方法

在光伏发电渗透率较高的配电网储能系统（ESS）规划中，为充分挖掘分布式储能的调节能力，实现配电网的经济稳定运行，提出了分布式储能多点布局的双层规划方法。结合储能电池（ESB）的运行特性模型，提出了考虑 ESB 使用寿命的多点储能协同运行策略。构建了规划-运行双层模型，外层考虑储能电池规划的总成本，确定储能电池的布局点数和容量，内层重点考虑储能电池的利用率和配电网的运行稳定性。采用混合粒子群优化和非支配排序遗传算法求解分布式储能多点布局的规划和运行结果。实例分析表明，配置多点布局ESS后，总规划成本降低了20.25%，ESB利用率提高到50%以上，配电网电压波动率和损耗率分别降低了19.09%和11.76%。
