摘　　要：针对配电网电压质量评价较粗糙、对电网侧储能提升系统电压质量缺乏考虑的问题,提出一种兼顾配电网电压数据时序特性、线损以及运行经济性的电网侧储能优化配置方法。首先,基于电压双向越限、波动特性与时序趋势3个维度建立了电压质量多属性综合评价指标体系。其次,细化储能循环寿命计算方法,进而提出计及线损和循环寿命的电网侧储能效益模型;然后,建立了储能优化配置双层模型,上层最大化储能全寿命周期效益,优化其功率及容量。以配储后网络电压质量综合评价值最大与无功功率调节设备动作成本最小为目标,建立储能下层运行策略优化模型;最后设计算例验证了所提模型和方法的有效性。Aiming at the problem of rough evaluation of voltage quality in distribution networks and the lack of consideration for improving system voltage quality and coordinating with reactive power compensation equipment through grid side energy storage,an optimized configuration method for grid-side energy storage is proposed that takes into account voltage timing characteristics,line loss,and operational economy of the distribution network.Firstly,the multi-attribute comprehensive evaluation index system of volt-age quality is established based on the three dimensions of bidirectional voltage exceeding the limits,fluctuation characteristic and time series trend.Secondly,the calculation method of energy storage cycle life is refined,and then the energy storage benefit model of grid side is put forward considering line loss and cycle life.Then,a two-layer model of energy storage optimization configuration is established.The upper layer maximizes the life cycle benefit of energy storage and optimizes its power and capacity.Aiming at the maximum comprehensive evaluation value of network voltage quality and the minimum operation cost of reactive power regulation equipment after storage allocation,the optimization model of the operation strategy of the storage power layer is established.Finally,a numerical example is designed to verify the effectiveness of the proposed model and method.
