Abstract

Increased penetration of Electric Vehicle (EV) in the recent past introduces new type of load in the distribution system. Charging of EV may overload the system components, increase voltage deviation and system losses. To analyse the impact of charging of EV on distribution, there is a need of modelling of EV charging load. Currently Constant Power Load (CPL) is considered for the load modelling which does not represent dependency of charging load with the system voltage. In this paper, an accurate load modelling of EV is done considering the charging behaviour of EV. Single stage and multi-stage time variant coefficients of ZIP load model and exponential load model are estimated to model the voltage dependency based on the EV charging characteristics. Estimation problem is formulated as least square minimization problem. Quadratic Programming (QP) and Differential Evolution (DE) is used to solve the estimation problem for ZIP load model and exponential load model respectively.
