A novel research on green electric vehicle battery replacement station

New energy grid-connected power generation capacity is limited due to its volatility and uncontrollability. To solve this problem, a novel idea, "green electric vehicle battery replacement station", is proposed in this paper. This method combined both battery replacement station and new energy power station, and by applying appropriate control strategy, the batteries can be used to eliminate the output power volatility and uncontrollability generated by the new energy power station and reduces its adverse effects on power system. In other words, the application of new energy can also reduce the largest load demand of battery replacement station on power grid, and realize synchronous development between new energy grid-connected power generation capacity and battery replacement station. Simulation results prove that the proposed idea not only can achieve the above objectives, but also can reduce the line losses, improve power transmission efficiency as well as save electricity costs.
