Abstract :
In distribution system planning, it is essential to understand the impacts that EVs and the power electronics associated with their charging units may have on power distribution networks. A deeper understanding of these matters aids utilities in the design of electrical power systems, including asset planning, an example being selection of k-type rating for distribution transformers. In this paper we present a method utilizing a VHDL-AMS environment for modeling these nonlinear, time-varying loads.
