An orderly charge and discharge control method of considering electric vehicle V2G and photovoltaic complementation in residential area

摘要

In order to resolve the problems of distribution network overload and increased peak-valley difference caused by large-scale electric vehicles’ disordered charging, taking the residential community as the research object, an orderly charging method of electric vehicles (EVs) based on power line carrier communication was proposed, and a model of ordered charge and discharge control and load peak regulation considering the complementary of EVs V2G and photovoltaic (PV) was established. It makes full use of the ability of EVs to cut peaks and valleys and restrain the fluctuation of PV output, alleviates the load pressure of the distribution network and reduces the cost of network transformation, which not only brings great benefits to the owners of EVs and power supply operators, but also promotes the consumption of new energy.
