The effect of PEV uncontrolled and smart charging on distribution system planning

This paper presents a planning model for distribution systems considering various energy supply options such as distributed generation (DG), substations, and feeders. In addition, the impact of Plug-in-Electric Vehicle (PEV) uncontrolled and smart charging loads on the plan outcome is evaluated. A new optimal power flow (OPF) based optimization model is proposed to schedule PEV uncontrolled and smart charging loads. Test results are presented to demonstrate the effectiveness of the proposed model. The results show that PEV charging loads significantly affects the plan outcomes.
