Hi every body, I work on power network control and stability and I'm looking for a model of a network contains of 2 synchronous generators with one load. Does any one have this model in MATLAB mfile ?
Thanks, power_PSS in MATALAB is very complex model! We're looking for a model that be simple (just hast two generators, transmission lines and one load).

1. Transient Stability Analysis of Multi-machine System
Published by Khalid Akhtar
Power-system stability is a term applied to alternating-current electric power systems, denoting a condition in which the various synchronous machines of the system remain in synchronism, or "in step," with each other. Conversely, instability denotes a condition involving loss of synchronism, or falling out of step Occurrence of a fault in a power system causes transients. To stabilize the system load flow analysis is done. Actually in practice the fault generally occurs in the load side. As we controlling load side which will lead to complex problem in order to avoid that we are controlling the generator side. A MATLAB simulation has been carried out to demonstrate the performance of the three-machine nine-bus

A Multimachine Power System Stabilizer Using Fuzzy Logic Controller
Dr.A.Taifour Ali,Dr. Eisa Bashier M Taye,Ms. Kawthar A.Adam
Abstract
In this paper a fuzzy logic controller as power system stabilizer for stability enhancement of a multi machine powersystem is presented. Power system stabilizers (PSSs) are added to excitation system or control loop of the generating unit to enhance the damping during low frequency oscillations. In order to accomplish the stability enhancement, speed deviation and acceleration of the rotor of synchronous generator were taken as the input to the fuzzy logic controller.These variables
produce significant effects on damping of the generator shaft mechanical oscillations. The simulations were tested under different operating condition and the responses
of stabilizing signal were computed. The performance when compared with the conventional PID controller the results of fuzzy controller are quite encouraging and satisfactory.
Keywords adaptive controller, fuzzy logic, PID stabilizer,synchronous generators.
