摘要
针对家用电动汽车快速充电引起的电网电压突变、电流谐波污染等问题,提出一种将电池储能与分布式能源泛在互联的应用技术。以电池储能与泛在电力物联网融合架构为依托,确立了以智慧家庭储能系统为研究目标,建立了各子系统模型。采用住宅潮流计算与SimSES工具箱联合对3种家用电动汽车充电模式进行仿真,对电池寿命、电池SOC概率分布与家庭能源费用支出进行对比分析。仿真结果表明,通过泛在电力物联网对智慧家庭中各种能源的智能调度与分配,能实现对电池友好与减少能源费用支出的目标,对智慧家庭的实际建设提供了有力的理论支撑。
For the problems of abrupt changes in grid voltage and current harmonic pollution caused by fast charging of household electric vehicles,an application technology for ubiquitous interconnection of battery energy storage and distributed energy is proposed.Based on the integrated architecture of battery energy storage and UPIoT,the research goal of smart home energy storage is established,and its subsystem models are built.The residential power flow calculation and SimSES toolbox are used to simulate three charging modes of household electric vehicles.The battery lifetime,battery SOC probability distribution and household energy cost are compared and analyzed.The simulation proves that the intelligent dispatching and distribution of various energy sources in smart home through the UPIoT can achieve the goal of battery friendliness and reduction of energy costs,and provide a powerful theoretical support for the actual construction of smart home.
