A Survey of Algorithms for Distributed Charging Control of Electric Vehicles in Smart Grid
Electric vehicles (EVs) are an eco-friendly alternative to vehicles with
internal combustion engines. Despite their environmental benefits, the massive
electricity demand imposed by the anticipated proliferation of EVs could
jeopardize the secure and economic operation of the power grid. Hence, proper
strategies for charging coordination will be indispensable to the future power
grid. Coordinated EV charging schemes can be implemented as centralized,
decentralized, and hierarchical systems, with the last two, referred to as
distributed charging control systems. This paper reviews the recent literature
of distributed charging control schemes, where the computations are distributed
across multiple EVs and/or aggregators. First, we categorize optimization
problems for EV charging in terms of operational aspects and cost aspects. Then
under each category, we provide a comprehensive discussion on algorithms for
distributed EV charge scheduling, considering the perspectives of the grid
operator, the aggregator, and the EV user. We also discuss how certain
algorithms proposed in the literature cope with various uncertainties inherent
to distributed EV charging control problems. Finally, we outline several
research directions that require further attention.Comment: This article has been accepted for inclusion in a future issue of the
