Transient Stability Analysis of Wind Integrated Power Systems with Central Area Controller

It is widely accepted that transient stability is an important aspect in designing and upgrading electric power system. This paper covers the modeling and the transient stability analysis of the wind integrated IEEE 14 test bus system using Matlab Power System Analysis Toolbox (PSAT) package. A three-phase fault is applied in the test system and stability is analyzed. Later, area controller is implemented to analyze the system stability. The evaluation is illustrated by conducting two case studies, modified IEEE-14 bus system and southern Kerala grid. It was observed that addition of area controller improves the system stability and thereby the power system performance.
