Evaluation of Workplace Car-park for Electric Vehicle charging in a dense Urban environment

摘要

Plug-in Electric Vehicles will be proliferating in many urban societies around the world due to aggressive targets set-up by many Governments around the world. This trend will get a boost especially after the COVID-19 lockdown phase, when it was evident that Green House Gases in the atmosphere could be brought down by large extent in a very short-time. However, many urban areas are densely populated and many car owners do not even have a proper car park. In such case, how will they get an access to charging facility. In this paper, we present a model of an aggregated charging facility that is located as a work-place car park. The arrival and departure of PEVs are modeled using the office statistics. We show how this random variable can be represented as an electrical load to the grid. We then show charging strategies that can be used to ensure the PEVs have a full charge at the time of departure. This is to eliminate the need for residential charging as there may not be such a facility available. The charging of PEVs is carried out for minimize the loading on the grid and yet meet the constraints of the PEV users.
