Electrical Vehicle Impact on Distribution Network Power Quality

Published by Sampsa KUPARI, Metropolia, Helsinki University of Applied Sciences Abstract: The electrical vehicle form a huge load (and occasionally a generator as well) that is not resistive but possibly of nonlinear character. This may have an effect on distribution network power quality and possibly disturb seriously other consumers. If this is not taken careContinue reading “Electrical Vehicle Impact on Distribution Network Power Quality”
