在本文中，我们扩展了一个基于电路的电流-电压潮流公式，包括频率偏差和隐式模型发电机的初级和次级控制动作作为其时间依赖性的函数。这包括扩展松弛总线发电机模型，以更好地表示其频率控制的真实行为。这些隐式模型避免了外部迭代循环的需要，并在考虑频率偏差时提高了仿真收敛的鲁棒性。该仿真框架具有高度可扩展性，并在81 k+总线系统上得到了验证。
In this paper, we extend a circuit-based, current-voltage power flow formulation to include frequency deviations and implicitly model generator primary and secondary control actions as a function of their temporal dependence. This includes extending the slack bus generator model(s) to better represent its true behavior with frequency controls. These implicit models obviate the need for outer iteration loops and improve the robustness of the simulation convergence when frequency deviations are considered. The simulation framework is highly scalable and is demonstrated on 81k+ bus systems.
