Enhancement of voltage profile and loss minimization in distribution system using genetic algorithm

Abstract

Distribution system holds a very significant position in the power system since it is the main point of the link between the bulk power and the consumers .A planned and effective distribution is the key to cope with the ever increasing demand for domestic industrial and commercial load. The load flow study of the radial distribution network is of prime importance for effective planning of load transfers. Power companies are interested in finding the most effective configuration for minimization of real power losses and load balancing among the distribution feeders to save energy and enhance the overall performance of the distribution system. Distribution generation integration in distribution system is one of the options which give benefits like loss minimization, peak saving, over load relieving and improved reliability. Optimization and size of the DGs considering system loss minimization and voltage profile improvement as objective functions. The optimization technique based on genetic algorithm for optimum location and size backward sweep and forward sweep load flow method used for base load flow and this work is tested on standard IEEE 33 bus system. The simulation results are tested using matlab Simulink soft ware.
