摘　　要：电池储能设备具有可控化和模块化的特点,可广泛用于配电网系统,通过在台区调整储能设备的接入位置,观察台区线损变化情况,得出结论:储能设备接入光伏侧,电量基本被就地消纳,实现损耗降低;储能设备接入配变侧,光伏给储能充电时供电半径过大造成线损增加。在配电网的合理位置接入储能设备,有降低线损率的实际效果,可以为电网企业带来收益。Battery energy storage equipment has the characteristics of controllability and modularity,and can be widely used in distribution network systems.By adjusting the connection position of energy storage equipment in the substation area,observing the changes in line loss in the substation area,it can be concluded that when the energy storage equipment is connected to the photovoltaic side,power generation is basically absorbed on site,achieving loss reduction;The energy storage equipment is connected to the distribution transformer side,and the power supply radius of photovoltaic charging for energy storage is too large,resulting in increased line loss.Connecting energy storage equipment at a reasonable location in the distribution network has the practical effect of reducing line loss rate and can bring benefits to power grid enterprises.
