Load Flow Analysis of Unbalanced Radial Distribution System Influence of COVID-19 Lockdowns and Electric Vehicles Charging Demand

From 2020 – 2021, COVID-19 causes such problems in Thailand. Consequently, lockdown restriction people lead to increasing electric demand in resident areas. This work proposes a load flow analysis of the unbalanced radial distribution system influence of COVID-19 and electric vehicle (EV) charging demand. The study’s focus parameters are power quality issues such as voltage magnitude variation and power losses. The scenarios of electric vehicle charging demand also include and declare the results. Therefore, the contribution of this work is the best case study for the future operation and planning of the distribution system.
