Abstract
Distributed generator (DG) is now commonly used in distribution system to reduce total power loss and to improve the power quality of the network. The major task of connecting DG units is to identify their optimal placement in the system and to evaluate the amount of power to be generated in the DG. By considering this objective, a hybrid technique using Genetic algorithm and Neural-network is proposed in this paper. By placing DGs at optimal locations and by evaluating generating power based on the load requirement, the total power loss in the system can be minimized without affecting the voltage stability of the buses. Due to reduction of total power loss in the system and improvement of bus voltages, the power quality of the system increases. The results show the improved performance of proposed method for different number of DGs connected in the system.
