Abstract:
After the digital revolution, every customer in power system requires a reliable and quality power, even though it costs more. But, the dependency on fossil fuels is the major threat against the sustainable development of any developing country. Recently, the Distributed Generation (DG) with renewable energy sources creates an emerging way of fulfilling challenges and also provides vast opportunities in power generation, by evolving various novel technologies. Even though, the DGs are used to reduce system losses and increase voltage level, the inapt size and incorrect spot of DGs steer to higher power losses and appalling voltage levels. Therefore, this proposed work aims to explore the optimal locations and capacities of DG units, by using Final Node Voltage Discrepancy Factor (FNVDF) and NSGA II, respectively. The objectives of this work are to diminish the power losses and to get better voltage profile. The execution of this algorithm is illustrated in 33 and 69 bus radial distribution test systems and the results are compared with the results of GA. This proposed method proves its efficiency and hence, it encourages the new dimension of power system with increased volume of renewable energy sources.
