Minimization of power loss and improvement of voltage profileby optimal placement of wind generator in distribution network

摘要

Nowadays, distribution losses accounts to 25 to 30 percent, so minimization of these losses gain major role to maintain pow er system performance. Distributed generation (DG) could be considered as one of the viable options toease so me of the problems (e.g. high loss, low reliability,poor power quality)faced by the power systems, apart from meeting theenergy demand of ever grow ing loads.Inclusio n of a wind generator into distribution system will minimise the pow er losses and improves the voltage profile. Determination of optimal location of wind generator in the given distribution system is very important, as studies indicate that inappropriate selection oflocation and size of wind generator, may lead to greater system losses than the losses without placing it in the given distribution system. In this work, Analytical approach and Particle Swarm Optimization technique are used to determine wind generator size and its opti mal placement.A co nventional load flow technique called backward forward sw eep load flow is used for calculation. The results for the two approaches are compared and voltage profile of the 33-bus, 69-bus and 13-bus radial distribution test systems is observed
