Performance analysis of a grid-connected PV system in LV distribution network

Swarna, K.S.V., Arangarajan, V., Shafiullah, GM.ORCID: 0000-0002-2211-184X, Oo, A.M.T. and Stojcevski, A. (2015) Performance analysis of a grid-connected PV system in LV distribution network. In: International Conference on Power Electronics and Energy Engineering (PEEE) 2015, 19 - 20 April 2015, Hong Kong


Over the past decade, the growing demand of Grid-connected photo voltaic (GCPV) system has been increasing due to an extensive use of renewable energy technologies for sustainable power generation and distribution. High-penetrated GCPV systems enhance the operation of the network by improving the voltage levels and reducing the active power losses along the length of the feeder. This paper aims to investigate the voltage variations and Total Harmonic Distortion (THD) of a typical GCPV system modelled in Power system simulator, PSS SINCAL with the change of level of PV integrations in a Low Voltage (LV) distribution network. Five different case studies are considered to investigate the impact of PV integrations on LV nodes and the corresponding voltage variations and harmonics. In addition, this paper also explores and benchmarks the voltage improvement techniques by implementing On Load Tap Changer (OLTC) with respective to the main transformer and addition of Shunt Capacitor (SC) at appropriate node points in LV network...
