研究了电动汽车接入电网(V2G)提供备用服务与备用资源的优化配置问题。首先,建立了V2G备用服务的市场交易机制,并提出一种能够准确估计V2G备用服务实时可调度容量的等效变换方法。然后,以机会约束规划反映负荷波动、发电机停运、V2G出力偏差等随机性因素,构建了考虑备用经济性、可靠性及碳排放的多目标竞价模型。接着采用交互式决策方法处理该多目标优化问题,并结合随机模拟与改进粒子群算法进行求解。最后,进行了仿真分析,仿真结果证明了所提等效变换方法与备用服务多目标竞价模型的有效性。
This paper studies the optimal allocation of standby service and spare resources for electric vehicle access grid (V2G). First, the market transaction mechanism of V2G standby service is established, and an equivalent transformation method that can accurately estimate the real-time schedulable capacity of V2G backup service is proposed. Then, a multi-objective bidding model considering reserve economy, reliability and carbon emission is constructed based on the randomness factor such as load fluctuation, generator outage and V2G output deviation. Then, the multi-objective optimization problem is solved by using the interactive decision-making method, and combined with stochastic simulation and improved particle swarm optimization. Finally, the simulation analysis is carried out. The simulation results show the validity of the proposed multi-objective bidding model with equivalent transformation method and standby service.
