在本文中，我们提出了一种稳定的电网模型，其中具有光伏（PV）系统和车辆到电网（V2G）功能的电动汽车（EV）的家庭可以在并网和孤岛模式下运行。该模型用于研究负载瞬态、功率共享和故障分析。 The implemented control system overcomes challenging situations such as load changing and transient conditions by managing the power of the battery and PV and regulating the voltage and frequency in the islanded mode.最大功率点跟踪（MPPT）经过修改，包括在孤岛模式和充满电的电动汽车电池情况下限制功率的功能。此外，还采用下垂控制和虚拟惯量的统一控制方式。该模型在 MATLAB/Simulink 中实现，并使用 OPAL-RT 模拟器部署到实时仿真，以验证所提模型的可行性。实时仿真结果显示了控制器在负载变化和故障情况下的电压和频率调节能力。
In this paper, we propose a stable electrical grid model, in which a home with a Photo-Voltaic (PV) system and Vehicle to Grid (V2G) capable Electric Vehicle (EV) can operate in both grid-connected and islanded modes. The model is used for studying load transients, power-sharing, and fault analysis. The implemented control system overcomes challenging situations such as load changing and transient conditions by managing the power of the battery and PV and regulating the voltage and frequency in the islanded mode. The Maximum Power Point Tracking (MPPT) is modified to include a feature for limiting the power in case of islanded mode and fully charged EV battery. Furthermore, the droop control and virtual inertia is utilized in a unified control manner. The model is implemented in MATLAB/Simulink and deployed to a real-time simulation by using an OPAL-RT simulator to validate the feasibility of the proposed model. The results for the real-time simulations are presented, showing the capabilities for voltage and frequency regulation of the controller, in load variations and fault condition.
