• 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 electrical energy sector, due to its renewable sources of energy generation, such as photovoltaics (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 emitting around a quarter of total greenhouse gas emissions, therefore, EVs can be seen as being a potential solution. This article seeks to analyze, through a simulation in the OpenDSS software, plug-in electric vehicles connected to low voltage networks, aiming to identify how they can influence different aspects of distribution networks, mainly regarding the drop-in power. voltage, active losses and transformer overload, through the different charging modes (slow, intermediate and fast), so that it can be seen that there was an influence on the worsening of quality levels.
