Impact of Photovoltaic Ingress on Power Distribution System

In recent years, there has been a rapid growth in the installation of solar photovoltaic (PV) systems, due to many factors such as increase in energy demand, to produce green and efficient energy, to manage the cost of electricity bill etc. it is evident from the rapid growth of rooftop PV systems that it has many benefits but it is also very important to consider the impacts of high penetration of PV on the distribution network. In this paper, simulation on low voltage distribution network (LVDN)have been carried out in order to see the impacts of PV ingress. We have used k-electric (KE) network to analyze the overall system behavior such as voltage stability, line and cable losses and transformer losses.
