Minimising Power System Losses and Improving Voltage Profile Through Optimal PV Penetration

Abstract

In recent years, there has been a growing global interest in boosting the contribution of solar energy to electrical networks. This is because it is a clean energy source with no negative environmental impact. Furthermore, the development of solar panels is increasing, and so is the price decrease. High-voltage electrical power inverter manufacturing has also advanced, allowing solar energy units to be connected to high-voltage networks. Despite these advantages, there are numerous problems. With growing worry about global warming, most countries are advocating for a cleaner alternative to present fossil fuel-based generation systems. Photovoltaic (PV) installations are becoming more popular because of their adaptability. Compared to typical generation systems, PV is placed closer to load centres. This allows injecting PV at optimal locations and sizes to reduce system losses and improve the voltage profile. This paper considers the optimal PV penetration percentage size and location placement. Simulation is performed on the IEEE 14 bus system using Neplan software. When the system is optimised, the voltage profile improves significantly while losses are reduced.
