Smart EV Charging: A Global Review of Promising Practices

Abstract

The electrification of transport in Europe is in the early stages of a market transformation that has the potential to significantly cut emissions in both the transportation and energy sectors, while generating wider benefits for society. The research underpinning this study finds that the greatest value from integrating electric vehicles (EVs) into the power grid can be generated by charging them when and where it is most beneficial for the power system, while ensuring consumers’ mobility needs are met at an affordable cost. An emerging body of research on electric vehicle grid integration focuses on modeling the cost of integration under various scenarios, but few studies look at the existing promising practices that are based on policy tools in use today. The authors of this study conducted a qualitative review of policies for EV grid integration in the EU and U.S. markets. We found that, in order to unlock the environmental and economic opportunities associated with market uptake, three policy strategies are most effective: costreflective pricing, intelligent technology, and integrated infrastructure planning. The study also explores the implications of these practices for policymakers and regulators in the EU.

Impact of Smart Charging for Consumers in a Real World Pilot

“…In recent years a number of studies have presented early results of pilots where smart charging was applied in practice [10,23,24]. Overall these studies confirm the opportunities of smart charging to significantly reduce grid impact and indicate that smart charging can be applied on a majority of sessions while still allowing them to reach a full state of charge.…”

“…In recent years smart charging has been an increased topic of research, initially more focused on modelling and simulating smart charging practices. Simulation models have been applied to analyze effects of smart charging on grid impacts [6][7][8], energy market prices [9,10] and matching of renewable energy profiles [11]. Typically studies indicate that grid impacts can be significantly reduced during peak moments, the extent to which largely depends on charging profiles and assumptions applied in the models [8,10,12].…”

How Smart Metering and Smart Charging may Help a Local Energy Community in Collective Self-Consumption in Presence of Electric Vehicles

“…Given the different impact of V1G and V2G on the battery charging infrastructure and economics, today's investments are mainly aimed at supporting the massive deployment of electric vehicles and to ensure the extensive presence of charging points with one-way chargers. Therefore, due to technical potentials [40] and promising practices [41] of smart charging, V1G seems today to be ahead in the competition with V2G and it is preparing to become the most popular technology for coordinating the charging of a multitude of electric vehicles. The lack of coordination can cause the overloading of distribution transformers at substations or the voltage deviation at buses of distribution network [42]; in this sense, V1G may reduce the demand of chargers in commercial and industrial hosts in real time [43], according to centralized and decentralized smart-charging schemes [44] or heuristic approaches [45].…”

A Survey of Hydrogen Energy and I-Energy Applications: Household Intelligent Electrical Power Systems

“…In this vein, some control structure entities (such as: Utility operator, aggregators and end-users) are defined. The entities aimed to explain the communication and the coordination process between neighbor's homes and node units [118]. The Smart neighborhoods (defined as Group of houses) are developed to ensure the best health, welfare as well enable each community to take charge.…”
