Abstract

Distributed generations (DGs) such as solar and wind generations are used as generation source in the microgrid. Due to the fluctuation of renewable energy sources, the battery energy storage system (BESS) is one of the essential components to control and improve the quality of power microgrid. However, a placement for BESS installation with minimizing line loss is one of the most concern problems. This paper aims to determine the optimal location of the BESS by using the analytical method with the line loss sensitivity index. A multi-period optimal power flow (OPF) and line loss analysis with BESS parameters were investigated considering the daily operation of a microgrid in connected mode. The simulation performed on the microgrid that wants to keep total power generation from DGs in BESS and low energy consumption from the utility. Microgrid includes 3 DGs (biomass, solar and wind turbine generators) to assess the robustness of BESS placement. The results confirmed the effectiveness of the presented method. The optimal location of BESS can reduce line power loss and power consumption from the utility.

基于分布式发电微电网日常运行的电池储能系统优化位置降低线路损耗

微电网的发电源采用分布式发电，如太阳能发电、风力发电等。由于可再生能源的波动，电池储能系统(BESS)是控制和提高微电网质量的重要组成部分之一。然而，将BESS安装位置与线路损耗最小化是最受关注的问题之一。本文的目的是利用线损灵敏度指数的解析方法确定BESS的最佳位置。考虑并网模式下微电网的日常运行情况，研究了考虑BESS参数的多周期最优潮流和线损分析。在微电网上进行了仿真，该微电网希望保持BESS中dg的总发电量和公用事业的低能耗。微电网包括3个dg(生物质能、太阳能和风力涡轮发电机)，以评估BESS放置的稳健性。实验结果证实了该方法的有效性。BESS的最佳位置可以减少线路损耗和公用事业的电力消耗。
