DISTRIBUTED GENERATION PLANNING FOR MINIMIZATION OF POWER LOSS AT PEAK LOAD ON RADIAL DISTRIBUTION SYSTEMS

Abstract

In recent years, the economical and technical importance of distributed generation (DG) has been demonstrated because of its benefits to both the power systems, and the consumers themselves to the extent that most developed and developing countries have constructed many DG units in the heart of their power systems. The main objective of this thesis is to search for the optimum sizes and sites for conventional DG units planning which maximize the power loss reduction at peak load condition of a radial distribution system while maintaining bus voltages magnitudes and feeder sections loading within permissible limits. The mathematical model considered has been developed considering three types of DG units with respect to reactive power generation. With respect to the best number of DG units, the mathematical model has been applied considering one DG unit, two DG units and three DG units where it is found that the reduction in power loss, for the feeder considered, is small between the cases of two and three DG units which suggests that two or three DG units can be best number.
