由于化石燃料的快速枯竭和巨大的环境污染，现在的焦点正在从传统的发电方式转变为位于配电电压水平的非传统DER。技术的进步和更多的研究在使用DER导致微电网和有源配电网的形成。当小型DER单元放置在靠近负载的网络中时，使网络稳定，因为它可以在网络外部发生任何故障的情况下以孤岛模式工作。本文提出了一种在有源配电网中降低损耗和提高母线电压的方案。小型可再生能源形式的DG，如太阳能光伏，风能，生物质能，最适合减少网络中的损失。然而，DG的放置不会导致满足网络的无功功率需求，导致在几个总线的电压。该欠压问题通过DSTATCOM的优化配置来解决。在MATLAB平台上，采用DLF技术进行潮流计算，并将LSF沿着电压偏差作为目标函数进行DG优化配置。该方法在33节点辐射状配电系统上进行了测试。(C)2017年工程学院，亚历山大大学。由爱思唯尔公司制作和主持
Due to rapid depletion of fossil fuels availability and huge environmental pollution, focus is now changing from traditional method of power generation to the non-conventional DERs located at distribution voltage level. Technological advancement and more researches in the use of DERs result in the formation of microgrids and active distribution network. Small DER units when placed in a network near to load, makes the network stable as it can work in islanding mode in case of any fault outside the network. This paper proposes a scheme for reduction in losses and improvement of bus voltages in the active distribution network. A DG in the form of small renewable energy resources such as solar PV, wind, biomass, is placed optimally for reduction of losses in the network. However, placement of DG does not result in fulfilment of reactive power needs of the network, resulting in under voltage at several buses. This under voltage problem is solved by the optimal placement of DSTATCOM. DLF technique is used in this paper for load flow calculations and LSF along with voltage deviation is used in objective function for optimal location of DG on MATLAB platform. The methodology is tested on 33-bus radial distribution system. (C) 2017 Faculty of Engineering, Alexandria University. Production and hosting by Elsevier B.V.
