摘　　要：随着家庭光伏、工业光伏的大量应用,配电网中光伏接入的比例越来越高,高比例的光伏接入势必导致配电网电压水平偏低,影响配电网的正常稳定运行。储能因其灵活的调节特性,被广泛配置在配电网中,通过切换工作状态可以较好地调节系统的电压水平。提出一种含光伏的配电网储能优化配置方法,采用灵敏度法计算配电网内储能的备选接入点,并基于这些备选接入点利用双层配置模型进行配置。在改进的IEEE 33节点验证了模型的有效性,计算结果表明,所提储能配置方法不仅稳定了配电网的电压水平,还降低了网损,大大缩短了计算时间,可以应用于实际工程中。With the application of a large number of household photovoltaic and industrial photovoltaic,the proportion of photovoltaic access in the distribution network is getting higher and higher,and the high proportion of photovoltaic will inevitably lead to the low voltage level of the distribution network,which affects the normal and stable operation of the distribution network.Energy storage is widely deployed in distribution networks due to its flexible regulation characteristics,which can well regulate the voltage level of the system by switching its own working state.In this paper,we propose a method for optimal configuration of energy storage in distribution grids containing photovoltaic,which adopts the sensitivity method to calculate the alternative access points of energy storage in distribution grids,and configures them based on these alternative access points using a twolayer configuration model.The validity of the model is verified at the improved IEEE 33 node,and the calculation results show that the energy storage configuration method described in this paper stabilizes the voltage level of the distribution network and also reduces the network loss,which greatly shortens the calculation time and can be applied in practical engineering.
