Decentralized control techniques for plug-in electric vehicles in MV/LV distribution networks

Abstract

Decentralized control techniques are acquiring more and more importance to efficiently manage a large number of distributed energy resources (DER). It is expected that, in the future, plug-in electric vehicles (PEVs) will act as DERs providing valued services to power grids. In addition, it has been proven that uncontrolled charging of PEVs will have a significant impact on the operation of MV/LV distribution networks. In this context, this paper presents a review on decentralized control approaches to adequately integrate PEVs in MV/LV distribution networks. Among these decentralized control techniques, optimal and droop based controls are the most common. Both have strengths and weaknesses, so, more research about mixing both methods is needed.
