基于MILP的PHEV入网效益评估模型求解及应用

Solution for Benefit Evaluation Model of PHEV Grid Connection Based on MILP and Its Application

插入式混合电动汽车(PHEV)已成为解决能源和环境问题的重要手段,为探讨未来大规模入网能否给电网与用户带来额外效益,以电力系统运行总成本最小化为目标,以区域电能供需平衡、电池电量平衡、机组爬坡率等条件为约束,建立了新的PHEV入网效益评估模型,并利用新的混合整数线性规划求解思路,使用分支和分割算法对建立的效益评估模型进行求解,通过算例对模型进行了模拟分析。结果表明,通过V2G技术,PHEV入网可为电网和PHEV用户带来显著效益。

Plug in hybrid electric vehicles（PHEV） has become an important means to solve the problems of energy and environment.In order to explore that if network access with a large scale in the future will benefit the grid and users,a new benefit evaluation model of PHEV connected grid is established.This model makes the minimum of the total cost of the power system operation as the objective,and sets the regional energy supply and demand balance,balance of battery power,the unit ramp rate as the constraints.The branches and cut plane algorithm based mixed integer linear programming（MILP）is used to solve the established model.The simulation analysis of the model is verified by an example.The results show that with the V2G technology,the PHEV connection grid can bring significant benefits for the grid and PHEV users.
