A comprehensive survey on charge scheduling of electric vehicles in smart grids in the 2010s

Abstract

Electric vehicles (EVs) are being introduced by different manufacturers as an eco-friendly alternative to vehicles with internal combustion engines, provided with several benefits. In the upcoming years, the count of EVs is expected to expand. However, the uncoordinated charging of these vehicles can put severe stress on the power grid. The problem of charge scheduling of EVs is an important issue and has seen significant research activity in the past few years. Thus, this survey paper intents to perform a review of 65 research works about this scenario that operate with different approaches under a diverse period of time. Particularly, this paper describes about the power flow model, scheduling control mechanism and type of charging followed in EVs. The performance measures recorded in each of the works are described here. Finally, a compact description on research gaps and challenges relying on this aspect is made that aids the researchers in doing future works.
