Optimal placement and charge/discharge scheduling of electric parking lots considering reactive power generation capability

Abstract

Increasing the number of electric parking lots (EPLs) in the distribution systems may have some important impacts on their performances. These impacts can improve or deteriorate the system's performance depending on the EPLs' charge/discharge scheduling (CDS), location and size of these resources. This paper presents an approach to firstly determine an appropriate charge/discharge scheduling for an EPL in a 24-hour time period. Secondly, the optimal location is specified for an EPL to reduce energy loss, improve voltage stability, and voltage profile considering the reactive power capability of the EPL's inverter. The proposed method is implemented on the IEEE 33-bus standard distribution system. The genetic algorithm and backward-forward power flow method are utilized to evaluate the effectiveness of the proposed method.
