Abstract

One of the main challenges of sustainable development is global climate change, resulting from the intense consumption of oil and coal derivatives. The transition towards a carbon-free world will be a challenge for this and future generations. The electric energy sector, due to its renewable sources of energy generation, such as photovoltaic (PV) and wind, becomes one of the main agents in the decarbonization of the global economy. In this context, electric vehicles (EV) gain great importance, as the transport sector is currently responsible for the emission of about a quarter of the total emissions of greenhouse gases, therefore, EVs can be seen as being a potential solution. This paper seeks to analyze, through a simulation in the OpenDSS software, plug-in electric vehicles connected in low voltage networks, aiming to identify how they can influence different aspects in the distribution networks, especially regarding voltage drop, active losses and overload in the transformer, through the different charging modes (slow, intermediate and fast), so that it can be seen that there was an influence on the worsening of the quality levels.
