Abstract

Nowadays, the global decarbonization and electrification of the world’s energy demands have led to the quick adoption of Electric Vehicle (EV) technology. Therefore, there is an urgent need to provide a wide network of fast Vehicle-to-Grid (V2G) charging stations to support the forecast demand and to enable enough autonomy of such devices. Accordingly, V2G charging stations must be prepared to work properly with every manufacturer and to provide reliable designs and validation processes. In this way, the development of power electric vehicle emulators with V2G capability is critical to enable such development. The paper presents a complete design of a power electric vehicle emulator, as well as an experimental testbench to validate the behaviour of the proposal.

Highlights

  • The development of the Smart Grid is contributing to the integration of renewable energy into the electric grid, which guides the needed decarbonization of energy consumption to deal with climate change and the depletion of fossil fuels

  • This paper presents the details of the design and development for manufacturing the electric vehicle emulator for testing V2G chargers, with power factor grid correction functionality

  • A V2G charger has been used as a HUT and it has been connected to the Electric Vehicle Emulator (EVE) through a CHAdeMO connection

Summary

Introduction

The development of the Smart Grid is contributing to the integration of renewable energy into the electric grid, which guides the needed decarbonization of energy consumption to deal with climate change and the depletion of fossil fuels This development is increasing the complexity of the electric grid [1], adding new power system elements which must provide reliable operation in all kinds of different situations. Thanks to the Vehicle-to-Grid (V2G) functionality, the EVSE can work both as a load or as a generation source, using the energy of the EV battery available for secondary purposes, such as peak shaving, load frequency control, demand response or the management of renewable energy surplus [2,3]. This paper presents the details of the design and development for manufacturing the electric vehicle emulator for testing V2G chargers, with power factor grid correction functionality.
