This paper presents an adaptive wide-area damping controller (WADC) based on generalized predictive control (GPC) and model identification for damping the inter-area low frequency oscillations in large-scale inter-connected power system. A recursive least-squares algorithm (RLSA) with a varying forgetting factor is applied to identify online the reduced-order linearlized model which contains do...

Problem statement: The inter-area power systems have special characteristic of the stability behavior. The improvement of inter-area power system is one of the important aspects in power system. Approach: This study applies the Static Synchronous Series Compensator (SSSC) to improve stability of inter-area systems. The SSSC is modeled and then is applied to be incorporated into the power system...

In this paper, two different approaches are applied to the Kundur two-area four machines network in order to select the most effective signals to damped out the inter-area oscillations. The robustness analysis, simulations and different results show that in the case of wide-area signals selection, the geometric approach is more reliable and usefull the the residue approach.Also, the result conf...
