Abstract—In the next few decades, solar PV and electric vehicles (EVs) will become a major potion in Thailand’s power system. In this paper, we aim to study the impact of future solar PV installation and EV charging on Thailand’s power system and to provide the efficient load demand management policy. Firstly, the future power load demand, solar PV installation, and the number of EVs are forecasted by ARIMA models. Next, various scenarios of EV charging demand are generated by varying the charging schedule which is controlled by a smart grid system and charging policy. Future load demand curve in each EV charging scenario is analyzed based on demand response and the effect to electricity power producer is discussed.
