【摘要】：基于电动汽车的可控负荷和移动储能特性,提出了面向综合能源楼宇的电动汽车辅助服务方案。首先,构建了含电动汽车接入的综合能源楼宇模型,并引入楼宇的能源运营商定价机制。其次,分析了电动汽车与综合能源楼宇的交互特性和互动机理,提出了综合能源楼宇层面的电动汽车常规辅助服务方案和紧急辅助服务方案。最后,以某冬季典型日场景为例,对所提2种辅助服务方案进行了仿真验证和结论分析。仿真结果表明,多能互补的综合能源楼宇促进了能源在终端用户层面的梯级高效转换和利用,提升了系统对电动汽车充电负荷的接纳能力;常规辅助服务方案能够增大综合能源系统热电协调运行的空间和灵活性,提高系统的光伏消纳率,能够显著降低用户侧热、电负荷用能成本和车主充电成本,在用电高峰时对系统亦有调峰作用;紧急辅助服务方案在楼宇供给侧的能源网络发生故障时能够提供系统备用,快速响应系统的状态变化,楼宇可在不增加储能和备用电源投资的情况下维持用户的热、电负荷供应。
[Abstract]:Based on the controllable load and mobile energy storage characteristics of electric vehicles, an auxiliary service scheme for integrated energy buildings is proposed.Firstly, the integrated energy building model with electric vehicle access is constructed, and the building energy operator pricing mechanism is introduced.Secondly, the interaction characteristics and interaction mechanism between electric vehicle and integrated energy building are analyzed, and the conventional auxiliary service scheme and emergency auxiliary service scheme of electric vehicle at the level of integrated energy building are put forward.Finally, taking a typical day scene in winter as an example, the simulation verification and conclusion analysis of the two kinds of auxiliary service schemes are carried out.The simulation results show that the multi-energy complementary comprehensive energy building promotes the cascade efficient conversion and utilization of energy at the end user level, and improves the system's acceptance of electric vehicle charging load.The conventional auxiliary service scheme can increase the space and flexibility of the coordinated operation of thermoelectricity in the integrated energy system, increase the photovoltaic absorption rate of the system, and significantly reduce the energy cost of the user side, the energy cost of the electric load and the charge cost of the owner.The emergency auxiliary service scheme can provide the system backup when the energy network on the supply side of the building fails, and can quickly respond to the change of the system state.Buildings can maintain heat and power load supply without increasing energy storage and reserve power investment.
