在本文中，我们提出了一个等效电路模型的电力系统网络，有利于强大的和有效的交流潮流模拟，使更广义的总线和线路模型的结合。的电路方程制定在直角坐标系中的电压和电流，使用图论算法，提供最佳的数值调节。一个电流源为基础的发电机模型的介绍，提供了更强大和更有效的收敛相比，我们原来的方法。我们表明，所提出的框架支持非线性模型与不敏感的初始猜测和收敛在几个迭代。我们说明了广义建模的能力，推导出一个模型，包括AC，DC和半导体组件的并网太阳能电池板系统。
In this paper we present an equivalent circuit model for power system networks that facilitates robust and efficient AC power flow simulation and enables the incorporation of more generalized bus and line models. The circuit equations are formulated in terms of voltages and currents in rectangular coordinates using a graph theoretic algorithm that provides for optimal numerical conditioning. A current-source based generator model is introduced that provides for more robust and efficient convergence as compared to our original approach. We show that the proposed framework supports nonlinear models with insensitivity to the initial guess and converges in few iterations. We illustrate the capabilities of generalized modeling by deriving a model for a grid-connected solar panel system that includes AC, DC and semiconductor components.
