Plugin power flow

Small and multiple producers of electric energy such as wind and solar have a right to inject power into a network in deregulated power systems. The flow pattern changes whenever a new generator is plugged in. The traditional power flow formulation is not suitable for computing these changes. Rigid specification of buses in power flow routines contribute to this shortcoming. We report a procedure that permits connection of any number of generators, loads or shunt reactors at any time, at any bus, and enables calculation of resulting power flows and voltage magnitudes. This `plugin power flow´ is expected to be suitable in deregulated systems with significant wind power, solar power etc. An added advantage of the method is that it does not need any iterative techniques for solution.
