微电网中以新能源汽车为分布式储能的价格引导机制

The Price Guidance Mechanism of New Energy Vehicles as Distributed Energy Storage in Microgrids

随着我国能源方向的转变,对可再生能源的开发利用变得越来越重要,而微电网正是实现大规模利用新能源的重要途径之一,因而以风、光等新能源为基础的微电网正成为研究的热点方向。针对微电网进行的控制策略研究和调度优化是保障其稳定、可靠、经济运行的基础,对提升新能源利用率具有十分重要的意义。与此同时,在接入微电网的众多负载中,具备储能功能的电动汽车还可以通过V2G技术参与微电网系统的协调运行,作为分布式储能设备的补充,不但可以降低系统的峰谷差,提高系统运行的稳定性和经济性,还可以让车主在满足日常出行需求的情况下,也得到一定的经济收益,实现电动车车主与微电网系统的共赢。

With the change of energy direction in China, the development and utilization of renewable energy is becoming more and more important, and microgrid is one of the important ways to realize large-scale utilization of new energy, so microgrid based on new energy such as wind and light is becoming a hot direction of research. The control strategy research and dispatch optimization of microgrids are the basis for ensuring their stable, reliable and economic operation, and are of great significance for improving the utilization rate of new energy. At the same time, among the many loads connected to the microgrid, electric vehicles with energy storage functions can also participate in the coordinated operation of the microgrid system through V2G technology, as a supplement to distributed energy storage equipment, which can not only reduce the peak-valley difference of the system, improve the stability and economy of the system operation, but also allow the owner to get certain economic benefits under the condition of meeting the daily travel needs, and achieve a win-win situation between the electric vehicle owner and the microgrid system.
