Análise probabilística do impacto da recarga simultânea de veículos elétricos em uma rede de distribuição europeia de baixa tensão

Abstract

The exponential growth of electric vehicles (EVs) over the years leads to research to analyze and assess the impacts due to the simultaneous recharge of these vehicles in the electric power system (SEP). EVs are significant single-phase loads, which when added to the predominant residential load can symbolize a big problem, as the low voltage networks and their devices were not dimensioned aiming at such an increase in demand. In addition to overload and undervoltage, the sudden connection and disconnection of these devices can generate transient impacts. This work proposes a probabilistic methodology to evaluate the impacts caused by the simultaneous recharge of EVs in the SEP, aiming at future projections, while evaluating the use of distributed photovoltaic generation and grid-connected batteries as a solution. In the simulations, the uncertainties regarding the parameters (location, profiles, generation/storage capacity, among others) will be considered. Monte Carlo (MC) simulations are used in all scenarios, aiming to obtain a probabilistic assessment of the impacts on energy quality, and verifying the impacts and efficiency of the scenario proposed as a solution. The analyzes and tests will be carried out in OpenDSS software, using a European low voltage IEEE network. All results will be presented and discussed.
