Metodologia para modelagem de curva de carga de estações de recarga rápida em rodovias considerando estado de carga

Abstract

As the concern with greenhouse gases emission increases, less pollutent alternatives are explored amongst various productive sectors in society. According to studies, around 15% of the global greenhouse gases emission comes from the transport sector, causing an increase in the development of environmentally cleaner means of transport. As such, electric vehicles (EVs) are highlighted as possible alternatives, which are passing through an increased adherence in the world’s biggest markets. However, according to the International Agency of Energy, this adherence will be limited as long as there is no diffusion of safe and efficient charging structure. Additionally, in order to improve the efficiency of these charging structures, it is vital to understand their dynamics. Therefore, this present work aims to develop a methodology for load curve modelling of fast charging stations in highways, emphasising in the definition of the vehicle’s state of charge utilizing its length traversed. To this end, the programming software Matlab will be used. As such, it is seeking to present a methodology for load projection in fast charging stations in order to allow distribution system’s operators higher precision in its planning, therefore increasing the general efficiency. The following work presents its objectives, its boundaries and contributions, a referential framework, the methodology used and an analysis of the results obtained. Beyond this, a study case is done according to the highway BR-216, more specifically in its Pelotas-Torres stretch, and it the load curves obtained are analysed.
