Optimal Placement and Sizing of Distribution Generator in Active Distribution System with Solar Farm using Grey Wolf Optimization Technique

Technological advances in current times lead to increased energy consumption, according to demand response (DR). The distribution system has an increased load, according to DR. So as protection against future distributed system failures, this paper presents the most appropriate real-time response to the requirements of the distributed system in operation. The main objective is to reduce the power loss and increase the voltage in the distribution system in real time. By using the Grey Wolf algorithm to determine the optimal location of the distributed generator (DG) connected to the solar farm on the IEEE 33 bus test system. The simulation results revealed that the DG was installed with the solar farm in bus positions 7 and 13 respectively. The result revealed a 2.7% decrease in system power loss from the original 3.95% and a voltage increase of 0.95–1 p.u.
