摘要
将V2G技术应用到微电网中,不仅可以提高微电网运行效率,还可以为电动汽车(EV)用户创造收益。提出了计及V2G技术的微电网最优运营规划策略。首先建立微电网设备的能量平衡模型及约束条件。再针对EV聚合商和微电网运营商分别独立和融为一体两种情况,设计不同的微电网运营优化目标函数,利用序列二次规划算法搜索微电网日常运营成本最小值。最后对住宅用户和商业用户两种对象进行仿真测试。结果表明,充分利用V2G技术,可以提高微电网能源的运营效率,降低微电网总成本。
The application of V2G technology to microgrid can not only improve the operation efficiency of the microgrid,but also create profits for electric vehicle(EV)users.For this reason,the paper proposes the optimal operation planning strategy for the microgrid with V2G technology.Firstly,the energy balance models and constraints of equipments in the microgrid are established.Then,considering EV aggregators and microgrid operators as independent entity and integration respectively,different objective functions for the microgrid operation optimization are established,and sequential quadratic programming algorithm is used to search the minimum daily operation cost of the microgrid.Finally,the simulation test is carried out for both residential and commercial users.The results show that making full use of V2G technology can improve the operation efficiency of the microgrid energy and reduce the total cost of the microgrid.
