A novel linearized power flow approach for transmission and distribution networks

Power flow computations are important for operation and planning of the electricity grid, but computationally expensive because nonlinearities size system equations. Linearized methods reduce computational time often have disadvantage that they not applicable to general grids. In this paper we propose a novel linearized power (LPF) technique is able handle PQ- PV-buses, works on both transmission distribution networks. This based previous work handling PQ-buses by connecting them artificial-additional ground buses. We extend idea PV-buses. Test-cases show LPF method leads similar accuracy as nonlinear (NPF) while significantly reducing computation time. Therefore, good alternative NPF methods.
