Abstract

In this paper a comprehensive and accurate study is proposed to investigate the PHEVs impact on residential distribution network. In order to evaluate the impact of PHEVs on distribution network, characteristics of PHEVs are accurately modeled. PHEVs characteristics including battery capacity, state of charge (SOC), and the amount of energy required for charging PHEVs. The proposed model is applied to a 33-bus system in order to evaluate and investigate the growth rate of PHEVs penetration levels on distribution network. Results demonstrate that the amount of peak load, loss, and peak to average ratio (PAR) increment due to PHEVs penetration growth. So, in order to reduce the peak load, loss, and PAR, demand response (DR) programs are proposed. Time of use (TOU) program is considered for performing demand response programs. Results depict that DR programs decrease the amount of peak load, loss, and PAR.
