Abstract

A fast and efficient power flow control method incorporating the automatic adjustment of phase shifting transformers (PSTs) for specified line flows is presented. The effects of a PST are represented by the power-injection model and the corresponding extension of the conventional load flow equations is made. Load flow control by means of a PST is modeled by appropriate additional equations. A special fast decoupled algorithm is developed for the solution of the power flow control problem. The high numerical efficiency and simplicity of the fast decoupled algorithm employed is demonstrated on cases of the present state of interconnections in Balkan Electric Power Systems (EPSs) which are operating as an island with respect to UCPTE.
