A New Pi-Equivalent Model of Wind Turbine Generating System for Load Flow Analysis

This paper proposes a method to incorporate a fixed-speed (or near fixed-speed) wind turbine generating system (WTGS) in the load flow analysis of interconnected electric power systems. The present paper also proposes a new steady-state model of the WTGS. The pi-equivalent circuit of the induction generator of the WTGS is employed in developing the new model. The model requires only one set of equations to describe the WTGS steady-state performances. It is, therefore, much simpler than the conventional pi-equivalent model.
