A comparative study of control techniques for power loss minimization in a distribution network

Power losses in electrical power systems especially, distribution systems, occur due to the several technical factors. These losses are due to inappropriate size of conductor, long distribution lines, low power factor, overloading of lines etc. The power losses cause economic loss and reduce the system reliability. The reliability of electrical power system can be improved by decreasing power loss of network and by improving voltage profile. In this paper, three grid strategies have been executed which are reactive power injection, transformer tap changing and real load sharing. Genetic Algorithm(GA) and Newton Raphson (NR) based power flow method are used on grid strategies to minimize power loss. These grid strategies are implemented on IEEE-30 Bus radial distribution system. A comparative analysis is performed between grid strategies using GA & NR with respect to real loss minimization.
