智能电网中电动汽车与微网联合运行的建模与仿真

利用多Agent建模方法构建微网负荷、电动汽车及发蓄电装置模型；利用离散事件建模方法构建换电站模型；利用系统动力学建模方法构建微网母线功率模型.仿真结果表明，电动汽车的接入提高了微网的日间高峰时段和夜间负荷，造成了电网峰值和峰均比的增加，需进一步增加微网蓄电装置以提高对可再生能源弃能的吸收和电动汽车充电能耗的补充；在充分的充电服务支持下，电动汽车对换电服务的需求较少；所提模型能够较好反映电动汽车与微网的联合运行过程，对实现微网安全性、可靠性和高效性运行具有重要作用.

Modeling and Simulating Joint Operation of PEV and Micro grid in Smart Grid

A model of the micro grid operations with plug in electric vehicles (PEVs) in the smart grid was proposed using the combined modeling method. The models of micro grid load， PEV， generation and storage devices were setup on the basis of the multi agent modeling method， the battery changing station model on the basis of the discrete event modeling method， and the micro grid bus power model on the basis of the system dynamics modeling method. The results demonstrated that the access of the PEVs increases the micro grid peak time load in the daytime as well as the load in the night， which causes the increase of the peak load and peak to average ratio (PAR)， so the electricity storage devices should be added to improve the ability to absorb the depleted electricity from the renewable energy sources and to supply the PEV charging service. Besides， with the sufficient charging service supporting， the PEVs have fewer demands on the battery changing service. The proposed models can well reflect the PEV and micro grid operation procedure， and shall be of great importance for the micro grid safety， reliability and efficiency.
