摘　　要：电池储能由于其高度可控性和模块化的特点,可广泛应用于配电网络,起到提高供电可靠性以及平滑负荷等作用。以钠硫电池为例,对储能电池系统进行了建模及计算仿真,并将仿真结果接入算例网络,使用潮流法进行了配网的线损计算。算例结果表明,在配电网络的合理位置接入合理容量的储能电池,并考虑电池本身的加热损耗后,有降低线损率的实际效果。Because of the characteristic of highly controllability and modularization,battery energy storage could be widely applied in the distribution network for improving the reliability of power supply and smoothing the load.Taking the sodium-sulfur battery for example,the modeling and simulation of the energy storage battery system were performed.The simulation results were connected to the example network,and the line loss of the distribution network was calculated by using power flow method.The example results showed that,if the energy storage battery with proper capacity was connected to the distribution network at a proper position,it was effective in reducing the line loss after the heating loss of the battery itself was considered.
