储能系统在平滑间歇式能源功率波动、削峰填谷、改善电压质量以及提供灵活的功率调节等方面都发挥了巨大的作用。主动配电网能否实现对间歇性可再生能源进行完整消纳以及网络优化运行，在很大程度上依赖于主动配电网的储能系统配置是否合理。文中从削峰填谷能力、电压质量以及功率主动调节能力3个方面建立主动配电网储能系统的多目标优化配置模型，并使用带权极小模理想点法求解该多目标优化问题，避免求解多目标规划问题复杂的 Pareto 前端曲面，简化了问题求解的复杂度。最后，通过算例验证了所提模型及其求解方法的有效性。

Energy storage systems play an important role in smoothing the power fluctuation of intermittent energy sources. They can also be effectively used to provide peak shaving,voltage quality improvement,and flexible power adj ustment.The efficiency of an active distribution network (ADN) to accommodating high penetration of intermittent renewable energy resources and its optimal operation depend on appropriate placement of energy storage systems.This paper develops a multi-obj ective optimal placement model for energy storage systems in an ADN with the three obj ectives of peak shaving capacity, voltage quality and power self-regulation capacity.Additionally,a weighted minimum module ideal point method is proposed to simplify the multi-obj ective programming problem by avoiding the Pareto front.Finally,the case study results demonstrate the effectiveness of the proposed multi-obj ective optimization model and its solution method.
