Synthetic dynamics power flow

This paper introduces an interesting and promising methodology for solving difficult power flow problems. The synthetic dynamics power flow (SDPF) approach is based on the simple principle that the dynamic response of a stable power system always decays to a stable equilibrium point. We therefore create and solve a stable artificial dynamic model whose quiescent state is the solution of the desired power flow problem. In theory, the method should converge any steady-state-stable power flow model, and it should never produce unstable solutions. Experience to date with a prototype is encouraging, and further research and development seem warranted. At present, the method is computationally rather slow. Its potential value is on problems where standard power flow methods fail or might converge to unstable points.
