Strategic Placement of PV and WTG in Low Power Distribution System for Improving System Efficacy

It is common for distributed generation (DG) systems to have a capacity of several megawatts, which may be utilized to generate electricity close to users. Consider that DGs are linked to the network at ideal locations. As a result, they will reduce network losses, improve voltage profile, increase network reliability, and gain from investment deferral for distribution feeder up-gradation. The simultaneous deployment of wind turbine generators (WTG) and solar photovoltaic (PV) generators are addressed in this work, considering their uncertain power generation characteristics for a day. DGs' placement and sizing issues were then addressed using Tunicate Swarm Algorithm (TSA), an evolutionary algorithm; incorporated into the IEEE 33-bus radial distribution system. Simulated findings demonstrate an improved voltage profile, increased minimum security margin by 7.8%, network loss reduction of 22.7%, and feeder investment deferral by a minimum of 13 years for distribution feeder up-gradation.
