Adequacy assessment of power systems with PEV charging loads considering customer behaviour

Electrifying the transportation sector will undoubtedly influence power systems in various aspects from network losses and cost of operation to system reliability. This paper presents a novel framework to evaluate the impact of PEV charging loads on composite power system reliability. An optimal power flow (OPF) based model combined with a minimum cut set approach is proposed to evaluate nodal and system reliability indices. In addition, the impact of PEV types, charging characteristics, driver behaviour, and time of use electricity price have been considered through a wide range of scenarios. As well, detailed studies that consider the IEEE RTS, demonstrating the applicability of the proposed technique, are presented.
