Abstract

The access of the distributed generation with strong volatility and the disordered charging of electric vehicles would threaten the stability operation of distribution network. Under the background, the concept of smart contract for the "photovoltaic householdcharging station" transaction scenario and its technical route are analyzed firstly. Then, with the goals of maximizing the revenue of the photovoltaic user and minimizing the cost of the charging station, the interactive model is constructed on the basis of the smart contract. Finally, the simulation results show that when the photovoltaic user and the charging station trade electrical energy, their economic benefits are improved. Although the revenue of the power company has reduced, the reasonable charging strategies by the charging station will help increase the onsite consumption rate of photovoltaics, reduce the fluctuation of the power interaction with the grid and facilitate the safety of the grid.
