Dynamic Stability Analysis of Generator with Power System Stabilizers Using Matlab Simulink

Abstract

<p> The dynamics in single machine been connected to an infinite power system bus is analyzed in this paper. This analysis requires certain amount of system modeling level. The main components of the system models are excitation system, synchronous machine and the Power System Stabilizer. The Simulink /Matlab are used as the programming tool for analyzing this system performance. Design optimization arobust PSS based on Genetic Algorithm (GA) approach has been improvement. A proper design is required for this Power System Stabilizer (PSS) performance using the Particle Swarm Optimization (PSO) to archieve this. Then the implemented of the model and response of the dynamic system is been analyzed. The designed without PSS showed an unacceptable system response since as shown in the simulation results, system response with PSS proven to have improvements and PSS succeeding in stabilizing an unstable system. Therefore this leads to stability of the performance of the generator.</p>

Coordination of SPS and CES to Mitigate Oscillatory Condition on Power Systems

“…The identity matrix and eigenvalue are indicated by I and 𝜆. Moreover, mathematical representation of complex eigenvalue can be described as (7) [26,30]. Furthermore, frequency oscillation and damping performance of the system can be calculated using equation ( 8) and (9).…”

“…Another way is by installing PSS in the exciter of the generator [2]. The application of PSS to mitigate oscillatory condition has been investigated extensively in the last few decades [4][5][6][7]. However, PSS alone is not effective enough to overcome oscillatory condition because of significant increasing of load demand.…”

Concentrating Power for MPPT Solar PV Module forming Channelization of Efficient Energy

“…These characteristics are obtained by measuring the array volt-ampere for a different luminous intensity or intensity of photons over arrays [1] [4] [8]. These characteristics obtained from the optimum output characteristic curve of voltage (V) or current (I), related to the focusing maximum power point tracking, can be calculated and calculation has been measured as per different intensity levels [3][4], [10]. It is clearly seen in Figure 2 that the current increases as the irradiance levels increase.…”

“…The MPPT tracking concentrate on rapid increases in accurate results with a sudden rise in positive slope proportional to the illumination [3][4]. The sequential parameters which tend to affect the irradiance and illumination levels on a surface of the panel at a fixed tilt on rotation of the earth on daily basis and revolution of earth depending upon the seasonal solar path, the formation of clouds (weather conditions), pollution and dust between the surface of panel and the sunlight, and the shade of the object positioned such that the illumination level is reduced, etc [4], [10].…”
