The hydro turbine dynamics have a considerable influence on the dynamic stability of power system. In the study of dynamic stability, the system is modeled by the linear differential equations (small  signal analysis). Small signal stability of power systems is needed in all conditions and only is dependent on the conditions of power system performance before commotion occurrence. This paper pr...

This paper presents a new strategy based on Multi-stage Fuzzy (MSF) PID controller based on Artificial Bee Colony (ABC) for damping Power System Stabilizer (PSS) in multi-machine environment. The recent studies in artificial intelligence demonstrated that the ABC optimization is strong intelligent method in complicated stability problems. Also, finding the parameters of PID controller in power ...

This study proposes a novel modified grey-wolf optimization algorithm (MGWOA) to enhance power system stability. The stabilizer and static synchronous series compensator (SSSC) are used as damping controllers. Additionally, fractional-order PID (FOPID) controller is handle the nonlinearities thus achieve better performance. control parameters tuned using proposed MGWOA method which has been ver...

This paper deals with a discrete-time stochastic control model design for random failure prone and maintenance in single machine infinite bus (SMIB) system. includes the practical values of failure/repair rate transmission lines transformers. The probability matrix is, therefore, calculated accordingly. considers two extreme modes operations: most reliable mode least contingency case. allows wh...

Power systems interconnected by weak tie lines can be subject to low-frequency oscillations because of disturbances which excites the modes system; furthermore, these stable or unstable. The latter, if not treated, cause severe that divide network into smaller groups oscillate against each other, leading out-of-step (OOS) condition in network. detection OOS is a challenge for power system opera...

in this paper, the unified power flow controller (upfc) is enhanced with a chaotic particle swarm optimization (cpso) damping controller in order to mitigate the low frequency oscillations (lfo) in a single machine infinite bus (smib) power system. the designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...
