摘要
针对高渗透可再生能源与电动公交车接入系统带来的弃风弃光及总用电负荷波动问题,提出了一种考虑电动公交车“车到网”(vehicle to grid,V2G)响应的区域综合能源系统两阶段优化调度方法。首先,考虑电动公交车运营计划,将电动公交车集群V2G响应嵌入到区域综合能源系统优化调度之中,形成以整个系统总运行成本最小为目标的第一阶段调度策略;然后,第二阶段调度模型在第一阶段优化结果的基础上,以系统中所有用电设备产生的总电负荷波动率最小为目标,进一步优化各设备调度计划和能源交互策略;最后,对比分析4种场景下电动公交车集群与各能源设备协调调度的结果,仿真表明所提模型能够提高区域综合能源系统的风光消纳能力和运行经济性,同时减小系统的总用电负荷波动,验证了该调度方法的有效性。
Aiming at the problems of wind and photovoltaic power curtailment and total electrical load fluctuation caused by high permeability renewable energy and electric buses access to the system,a two-stage optimal scheduling method of regional integrated energy system considering the vehicle-to-grid(V2G)response of electric buses was proposed.Firstly,under the condition of satisfying the operation plan of electric buses,the V2G response of electric bus cluster is embedded into the optimal scheduling of regional integrated energy system,and the first-stage scheduling strategy is formed with the goal of minimizing the operation cost of the whole system.Then,based on the optimization results of the first stage,the second-stage scheduling model further optimizes the scheduling plan of each equipment and energy interaction strategies with the goal of minimizing the fluctuation rate of total electrical load generated by all electrical equipment in the system.Finally,the results of coordinated scheduling of electric bus cluster and energy equipment in four scenarios are compared and analyzed,the simulation shows that the proposed model can improve the capacity of wind and photovoltaic power accommodation and operation economy of the regional integrated energy system,and reduce the fluctuation of the total electrical load of the system,which verifies the effectiveness of the proposed scheduling method.
