S. Abhyankar, Q. Cui, and A. J. Flueck, "Fast Power Flow Analysis using a Hybrid Current-Power Balance Formulation in Rectangular Coordinates," Preprint ANL/MCS-P3082-1112, November 2012. [pdf]

Power flow is the backbone of steady-state analysis of power systems. Various steady-state applications such as contingency analysis, transfer limit calculations, and initialization of transient stability simulation, etc., hinge on the solution of power flow analysis. Hence, any performance improvement in power flow will improve various steady-state applications. In this paper we present a fast power flow analysis using a hybrid current-power balance formulation with the variables expressed in rectangular form. The computational efficiency and robustness of the proposed algorithm is presented for several test systems ranging from 100 to 3000 buses.
