Application Of Artificial Immune System To Design Power Systems Stabilizer

Conventional power system stabilizers contain a phase lag/lead network for phase compensation and have played a very significant role to enhance the stability of power systems. Various new approaches have been proposed in the past 30 years to improve the performance of power system stabilizers such as modern control and artificial intelligence techniques. In this paper a new method of control will be implemented to a power systems stabilizer. This approach uses the artificial immune controller called the improved varela immune network controller or IVINC. The purposes of IVINC controller are to enhance the stability of power systems and to damp low frequency oscillations.
