Original scientific paper This paper presents a heuristic algorithm PSO based simultaneous coordinated tuning of the SVC damping controller and power system stabilizer (PSS) in a two machine three bus power system. The coordinated tuning of PSS and SVC damping controller is converted to an optimization problem which is solved by particle swarm optimization (PSO) technique. The parameters like rotor angle deviation, settling time of disturbances post fault and transmission line active power are observed. The results obtained with PSO tuned SVC and PSS are compared with those of conventional PSS and Fuzzy controlled SVC and PSS. PSO tuned SVC and PSS gives better results. The effectiveness of each control method is verified using MATLAB. The results also show that the proposed coordinated controllers have increased power system oscillations damping capability.

Koordinirano podešavanje PSS i SVC regulatora prigušenja pretvara se u problem optimizacije koji se rješava tehnikom optimizacije roja čestica (PSO). Promatraju se parametri kao što su kut otklona rotora, vrijeme smirenja smetnji i aktivna snaga dalekovoda. Rezultati dobiveni od SVC i PSS podešenima na PSO uspoređeni su s onima dobivenim od SVC i PSS uz konvencionalni PSS i FLC. SVC i PSS podešeni na PSO daju bolje rezultate. Učinkovitost svake metode kontrole provjerena je primjenom MATLAB-a. Rezultati također pokazuju da su predloženi koordinirani regulatori povećali sposobnost prigušenja oscilacija energetskog sustava. Ključne riječi: optimizacija roja čestica (PSO); stabilizator energetskog sustava (PSS); statički var kompenzator (SVC); regulator neizrazite logike (FLC)

Abstract-The paper presents a new method for design of power system stabilizer (PSS) based on relay-free sliding mode control technique. The control objective is to enhance the stability and to improve the dynamic response of the single machine infinite bus (SMIB) system. We apply this relay-free sliding mode controller to design power system stabilizer for demonstrating the availability of the proposed approach.Index Terms-Relay-free sliding mode control, power system stabilizer, fast output sampling, robust control.

“…Thus, PSS gain has certain limitations in suppressing LFO. The setting gain of PSS is recommended to be chosen about 1/3 of its critical gain [23][24][25]. Therefore, PSS gain is required to be no more than 1/3 of its critical gain in the "Guide for setting test of power system stabilizer" [19].…”

Abstract:Power system stabilizers (PSSs) are widely used for suppressing low frequency oscillations in practical power systems. However, according to the requirement of the "guide for setting test of power system stabilizer" of China, PSS gain is limited to no more than 1/3 of its critical gain. As a result, PSSs may not provide enough damping to the inter-area mode oscillations. Through analyzing the Heffron-Phillips (H-P) model of the generator with PSS, it is found that exciter mode will become unstable when PSS exceeds its critical gain. This exciter mode is formed by the natural characteristic of the exciter-PSS loop. To address this problem, a novel PSS with a parallel component added to the conventional PSS is proposed to improve its critical gain. Therefore, large gain can be chosen for the proposed PSS to meet the critical gain requirements of the guide and provide enough damping to the inter-area modes simultaneously. Simulation results on the Ximeng coal power station of China verify the effectiveness of the proposed PSS.
