Coordinative Optimal Design for PSS and Auxiliary Damping Controller on SVC under Multi-Operating Conditions

Article Preview

Abstract:

Based on power system stabilizer (PSS) and the damping controller of flexible AC transmission system (FACTS),a problem of optimal design is researched by the example of static var compensator (SVC). Minimum damp ratio of system electromechanical oscillation modes eigenvalue in the weak damping operation condition is selected as the object function. Parameters of damping controllers are optimized by the algorithm which is combined by genetic algorithm (GA) and back propagation (BP) neural network based on adaboost (Ada-BP). Simulation shows the optimized damping controllers can restrain the low frequency oscillation in multi-operating conditions of system. The algorithm provides an effective solution for optimization calculations which calls the complicated calculations.
