A Robust Controller For Power System Stabilizer By Using Artificial Bee Colony Algorithm

In this paper, the model of 4-ordered linear Philips-Heffron synchronous machine is presented; the aim is to stabilize the synchronous machine connected to an infinite bus by using PID controller. Optimal parameters of controller are obtained by minimizing of the objective function which removes the unstable eigen-value to the left side of imaginary axis. The parameters of this controller are obtained by using artificial bee colony algorithm and finally compared by particle swarm optimization. Here, controller is computed for all operating points. Results show that the using artificial bee colony algorithm is a better performance toward the particle swarm optimization.
