Operation of EV charging station with a photovoltaic system to reduce the impact on the distribution grid

The development of technologies and solutions for electric mobility has been leading to the electrification of transportation. In countries such as Brazil, it has been observed that the number of electric vehicles (EV) has grown exponentially in recent years. The EV fleet electrical load can cause undesirable impacts to the low voltage distribution network, which is usually not planned to meet high power in the short term. In order to reduce the dependence on the supply from the electrical power grid and mitigate the impacts of connection to the distribution system, the use of photovoltaic solar generation systems (PV) as a primary energy source can be an environmental friendly and economically attractive solution. In this context, this work presents the simulation of the operation of EV Charging stations equipped with a photovoltaic solar generation system. The EV charging stations load power curves are compared with PV generation curves. The results are validated taking as reference the electrical data and climatic parameters associated with a microgrid equipped with a solar generation system, EV Chargers and a Battery Energy Storage System.
