中文摘要:

      伴随以整县光伏为代表的分布式新能源快速增长，以电动汽车为代表的新型电力负荷的不断接入进一步影响了源荷平衡特性，储能和柔性互联等灵活性调节资源是解决源荷平衡的重要手段。面向含风电、光伏、储能、电动汽车和柔性互联所组成的源-荷-储系统的典型拓扑和应用场景，结合电动汽车负荷的随机性和无序性，综合考虑能量平衡、运行平衡、供电可靠和功率波动等约束条件，通过充分利用电动汽车和柔性互联存量化灵活性调节资源，获得储能系统的优化配置方法，基于源-荷-储系统的优化控制策略，可以进一步降低储能配置，在满足区域电网内新能源最大消纳场景下实现储能系统的最优配置。

英文摘要:

      With the growth of wind power and photovoltaic generation, and the increasing of electric vehicle application, the balance characteristics have been furtherly affected between renewable energy and electric load, several resources are used as flexible regulation for the safety and stability of power system, such as energy storage system（ESS）and flexible interconnection（FI）. It is focus on the typical topology and application scenarios wind generation （WG）- photovoltaic（PV）-ESS- electric vehicle（EV）FI, combined with the randomness and disorder of electric vehicle load and the constraints such as energy balance, operation balance, reliable power supply, power fluctuations, the configuration method of the ESS is proposed, meanwhile, the proposed control optimization method leads to the configuration of the energy storage system can be greatly reduced by optimizing the control strategy. Under the same control and operational effect, the optimal configuration of the ESS is established.
