This paper investigates the critical parameters of power systems which affect the stability of the system. The analysis is conducted on both a single machine infinite bus (SMIB) system and a large multimachine system with dynamic loads. To further investigate the effects of dynamic loads on power system stability, the effectiveness of conventional as well as modern linear controllers is tested and...
This paper presents a robust excitation controller design for power systems to improve the dynamic stability following large disturbances. The controller is designed based on the partial feedback linearization where some parts of power systems need to be linearized. The robustness of the proposed control scheme is ensured by considering uncertainties within power systems model. In this paper, the...
This paper presents a novel large-disturbance controller for power systems with significant induction motor (IM) load. Unlike the standard linearisation technique, a linearisation is used where the Cauchy remainder is included in the design process as a bounded uncertainty. Details of the process to obtain a bound on Cauchy remainder are given in the paper; the bound is used to design the robust minimax...
In this paper, we analyse the effects of the integration of various types of wind generators into power systems based on available (dynamic) transfer capability (ATC). The amount of static (shunt capacitor) and dynamic compensations (STATCOM) to restore1 and enhance the transfer capability for fixed speed wind generators integration is determined. In addition, we compare the effects of both fixed...
