Order Reduction and Stability Region for Multi-Time Scale Electric Power Systems
Owing to the complexity and multi-time scale natures of electric power systems, it is necessary to correct boundary of stability region of simplified system (approximate reduction order system). In this paper, one property of the semi-tensor product of matrix is proved, which play an important role in correcting the boundary of stability region. In this paper, secondorder correction formula of the boundary of stability region is presented for multi-time scale power systems, which decreases the errors caused by employing the approximate reduced model to instead of the exact reduced system. A simulation of one-machine infinite-bus electric power system is done to illustrate the validity of the second-order correction algorithm.
