Abstract
A representation by a complex power-complex voltage (S-E) graph is introduced for power networks in place of the conventional complex current- complex voltage (I-E) graph. In the S-E graph transmission lines flows are separated into transmitted and loss power. This leads to the formulation of the load flow algorithm based on dividing the network into a tree and a cotree and alternating flow computations on the cotree with voltage update along the tree either as a Jacobi or a Gauss-Seidel algorithm. The algorithm proves to be effective with consistent convergence. It handles constrains smoothly and is fully attuned to computing load flows on the compound HV-AC-DC network. Parallel processing can be applied with essentially no idle time. Proof of convergence was attained.Keywords
