Application of evolutionary programming in the assessment of dynamic stability

This paper presents Evolutionary Programming (EP) based optimization technique for estimating synchronizing torque coefficients, K_s and damping torque coefficients, K_d of a synchronous machine. These coefficients are used to identify the angle stability of a system. Initially, a Simulink model was utilized to generate the time domain response of rotor angle under various loading conditions. EP was then implemented to optimize the values of K_s and K_d within the same loading conditions. Validation with respect to eigenvalues determination confirmed that the proposed technique is feasible to solve the angle stability problems.
