Abstract :
This paper introduces a stability control scheme based on a Lyapunov direct method, the potential energy boundary surface (PEBS) method, and analytical sensitivity of the transient energy margin. It classifies the stability control means into two categories, admittance-based control (ABC) and generator input-based control (GIBC), and uses a comprehensive method to analyze the contribution of each control. The scheme can get the optimal control from all the available control means by sensitivity analysis and then verify it in the transient stability program. Fast and accurate control goal is obtained from this stability control scheme.
