Dynamic charging control strategy of EV considering accessing of renewable energy

Electric Vehicle (EV) is an important part of the worlds energy technology revolution and the countrys renewable energy strategy. Large-scale EV charging will bring impact and challenges for the operation of power system, interaction of charging and discharging of EVs, accessing of renewable energy, security and economic of power system operation, is an important problem in development of EV and renewable energy. Stabilizing power system fluctuations caused by accessing of renewable energy and EV charging, improving absorptive capacity of power system, are serious problems. The thesis analyze the effect of large-scale random charging on power system, than the modeling of EV charging considering accessing of renewable energy is established. The dynamic charging control strategy with multi-objective is proposed. The strategy sets the optimization of regional power peak-valley difference and Stabilizing power fluctuations as the control objectives.
