Abstract

This paper address a study of Low-Voltage (LV) distribution system composed by decentralized PV-BES and centralized BES in developing country. The purposes of work is to size the PV-BES which connected into grid. Genetic Algorithm (GA) optimization solver in MATLAB has been employed to size the maximum PV penetration and minimum BES of decentralization according to PV and load curves. A sizing strategy is developed to determine a centralized BES capacity at MV/LV substation. The centralized BES here will charge an energy while decentralized PV-BES output is higher than consumptions and it will be idle/discharged when the decentralized PV-BES output is equal or lower than consumptions. The simulation results achieved on a test system confirm a helpfulness of PV and BES integrated into LV distribution systems.

发展中国家农村分散式和集中式低压配电系统的研究
本文对发展中国家由分散式PV-BES和集中式BES组成的低压配电系统进行了研究。工作的目的是确定连接到电网的PV-BES的尺寸。利用MATLAB中的遗传算法优化求解器,根据PV和负荷曲线确定分散化的最大PV穿透量和最小BES。开发了一种确定中低压变电站集中BES容量的规模策略。集中式BES将在分散PV-BES输出高于消耗时充电,当分散PV-BES输出等于或低于消耗时,它将闲置/放电。在试验系统上的仿真结果证实了将PV和BES集成到低压配电系统中的有效性。
