摘要
指出电动汽车接入配电网将会使电力网络变得复杂,也会带来对电网运行模式和电能质量等多方面的影响。对电动汽车的蓄电池特性做出分析,应用随机性理论对电动汽车的充放电过程进行负荷预测和建立模型,然后将电动汽车负荷接入到某地区电网中进行具体的算例仿真分析,最后仿真曲线和量化计算的结果较好地验证了之前的理论分析,并为未来电动汽车接入电网的充放电策略提供一定的理论基础。
Vehicle-to-grid(V2G) technology will make the power system more complex,and influence the grid operation mode and power quality.Based on Stochastic theory,this paper analyzes the characteristics of EV batteries,makes load forecast and establishes model for EV charging and discharging process.Then the simulation test is made by connecting EV load to the grid in a certain area.The simulation curve and calculation results verify the foregoing theoretical analysis,and provide the theoretical basis for the future V2G charging and discharging strategy.
