Optimal Placement, Sizing and Operating Power Factor of PV for Loss Minimization and Voltage Improvement in Distribution Network via DigSilent

With the increase in concern of global warming, most nations are pushing for a greener option to the current fossil fuel-based generation schemes. Due to its versatile opportunities, Photovoltaic (PV) installations are becoming more widespread. Unlike the conventional generation systems PV is located closer to the load centers. This gives possibility of injecting PV at optimal locations to minimize system losses and improve voltage profile. Appropriate location and size of PV is vital for the stability of the system. This paper, considers different voltage stability indices to determine precise PV location, explores effects of PV sizing and impact of PV power factor fluctuations. To validate the stability of the proposed scheme, simulation is done for IEEE 33 bus system and IEEE 14 bus system with DigSilent. When system is optimized it showed a great improvement to the voltage profile with considerable loss reduction.
