论文摘要
本文开发了一个新的分析模型，以估计由动态网络重新配置（DNR）产生的网格频率和电压的实时变化。在提出的模型中，切换操作被认为是入学矩阵中的离散变化，从而导致节点注入电流的步骤变化。然后将具有离散接收变化的网络模型与同步发电机和电压依赖性载荷的动态模型集成在一起，从而对DNR启动的动态网格操作进行分析。进行案例研究以通过与常规模型和全面的MATLAB/SIMULINK模型进行比较来验证所提出的模型。
This paper develops a new analytical model to estimate real-time variations in grid frequency and voltages resulting from dynamic network reconfiguration (DNR). In the proposed model, switching operations are considered as discrete variations in an admittance matrix, leading to step variations in node injection currents. The network model with discrete admittance variations is then integrated with dynamic models of synchronous generators and voltage-dependent loads, enabling analysis of the dynamic grid operations initiated by the DNR. Case studies are performed to validate the proposed model via comparison with a conventional model and a comprehensive MATLAB/SIMULINK model.
