Optimization of Multiple DG Placement for Minimizing Power losses and Voltage Profile Improvement Through Harmony Search Algorithm

Optimal placement and sizing of DG in distribution network is an optimization problem with continuous and discrete variables. Many researchers have used evolutionary methods for finding the optimal DG placement and sizing. This paper proposes a harmony search algorithm (HSA) for optimal placement and sizing of distributed generation (DG) in radial distribution system to minimize the total power loss and improve the voltage profile. The proposed harmony search algorithm is used to determine optimal sizes and locations of multi-DGs. Test results indicate that HSA method can obtain better results than an existing analytical method on the IEEE 33-bus system. Moreover, voltage profile improvement and branch current reduction are obtained
