Electric vehicles charging in a smart microgrid supplied with wind energy

This paper compares the performance of smart charging and dumb charging applied to Electric Vehicles (EVs) by implementing a simulation model. The model was developed based on the trend of current electric vehicle adoption in Norway. The electrical network system considered includes wind turbine to supply electric power to a group of 38 households. The assumed scenario is that the households own 31 EVs, which is equivalent to 60% of current EV adoption in Norway. The network is an almost stand-alone network as it mainly relies on wind power and if needed, power is purchased from the Nordic spot market. The obtained results indicate that the smart charging has several advantages if it is used with the support of energy storage: it prevents the event of peaks in electricity demand, it increases the use of wind power and it reduces the dependency from the spot market.
