Hardware in the loop Framework for analysis of Impact of Electrical Vehicle Charging Devices on Distribution network

Abstract

The spread of electric vehicles is strongly connected to the development of new charging technologies and their impact on the electricity distribution networks. This impact can be of different types: uncoordinated power absorption from the electricity grid, introduction of disturbances due to battery chargers, uncontrolled use of charging systems as a source of energy, interference with protection devices, creation of sub-nets powered by the battery even in the event of disconnection from the grid. It becomes important to have a test scenario where these strategies can be implemented. In this paper a framework based on Hardware in The loop (HIL) simulations is presented for the study of the impact of charging technologies on power grids, protections and as a test environment for coordination and supervision algorithms.
