Modelling and Cost/Benefit Analysis of Bidirectional Charging of EVs

Abstract

[EN] Renewable energy sources have been penetrating on a large scale during the last few years. They are increasing so quickly to reduce the power generation of conventional generation plants, reducing carbon emissions; moreover, electrification in the transport sector is increasing internationally, increasing the integration of EVs in the grid, elevating the energy consumption in the grid systems of all the countries. Fuel cars are being replaced by electrical vehicles increasing the demand for electricity and creating new challenges and opportunities for the operation of the grids. These opportunities must be valued exhaustively, considering different stakeholders' environmental impact and economic benefits. The EV'S can be a useful tool capable of providing an extensive range of flexibility in the operation of the grid in the ancillary services, moreover, contributing to reducing the importance of the conventional plants of generation and creating a new sustainable market that is more accessible and variability. In the current project, three different cases related to frequency control are studied, i.e., three different simulations to assess the feasibility of providing frequency control; therefore, different usage schedules and battery levels of the EV fleet will be used.

[ES] Los coches eléctricos representan una oportunidad para la red y los consumidores finales: medioambientalmente, economicamente y los beneficios del sistema eléctrico son posibles con tecnología de carga bidireccional. El almacenamiento de energía suministrado por los coches eléctricos puede ser usado para proveer flexibilidad a los consumidores finales. Muchos casos estan habilitados, como la provision de servicios a la red para transmisión y distribución de los operadores del sistema, así como para los clientes finales a través de la optimización del autoconsumo, con lo cual, el fundamento de este proyecto es habilitar un analisis de coste/beneficios de provision de flexibilidad porporcionado por los coches eléctricos en diferentes escenarios, concretamente en el control de frecuencia. Con la simulación nosotros vamos a ser capaces de definir varios escenarios y la posibilidad de definir beneficios de la flexibilidad que nosotros podemos usar de los coches eléctricos para los servicios auxiliares que deben asegurar los operadores del sistema
