Small Disturbance Stability Assessment in Power Grids with Wind Generators
Objectives: The effect of intermittent wind energy penetration into the power grid has increased considerably over the past decade. This intermittent nature of wind penetration causes electro mechanical oscillations which get transferred to the power network. This paper investigates small perturbation stability issue of a multi generator power system with one of the synchronous generator substituted with cage type wind generator. Methods/Statistical Analysis: A9 bus power network with synchronous generators is taken into consideration for carrying out the small disturbance (perturbation) analysis. A wind generator is substituted in place of a synchronous generator to verify the small perturbation stability. The oscillatory modes of the multi-generator power network are introspected. To have quick settling of oscillatory modes a converter based Static Synchronous Compensator (STATCOM) and a passive Static Var Compensator (SVC) are used with necessary stabilizing controllers. The findings from the perturbation analysis would help us in locating the FACTS stabilizers at critical sites for damping the power swings caused due to wind generators.
