Abstract

This paper provides an assessment on voltage profiles of a distribution system in the presence of high level of solar rooftop PV penetration. Each household solar rooftop PV power generation is calculated by PVWATTs online calculation tool. Load profile of South-West Chiang Mai City of the Provincial Electricity Authority (PEA) of Thailand is selected for the simulation. Simulation results indicate the maximum allowable PV installation per household in which voltage level do not exceed standard operating limits. Finally, sensitivity analysis of feeder length, transformer short circuit resistance and solar rooftop-PV inverter operating power factor are shown.
