Power system stabilizers (PSSs) associated with generators are mandatory requirements for damping low-frequency oscillations of a multimachine power system. Nevertheless, PSSs work well at particular network configuration and steady-state conditions for which they were designed. Therefore, the aim of this paper is the design of a robust PSS able to ensure the stability of the system for a wide range...
In this work, we are interested in the experimentation of an autonomous wind energy conversion system (WECS) using a test bench emulating a variable speed wind turbine (VSWT). This wind generator is connected to isolated loads through a DC bus and an inverter. The regulation of the DC bus voltage is carried out by a DC load controlled by a chopper. The goal of our work is to show the load voltage...
In this paper genetic algorithm (GA) is applied in order to design a PSS/AVR controllers with the goal of improving both transient stability and voltage regulation of power system under a symmetrical three-phase short circuit fault. A comparison based on simulation is then performed between the proposed approach and the classical controllers (manual control, AVR with no PSS, AVR with PSS). The simulation...
