Ramesh A.Jaya Laxmi Journal on Electrical Engineering 2230 – 7176 5 3 1 8 VSC-HVDC, Fuzzy Logic Control, Damping of Power Oscillations, Proportional Control, Stability In planning and operating today’s stressed power systems, the ability to maintain voltage stability has become a growing concern. Although the term voltage stability is being extensively used in the literature and in industry, general agreement on exactly what constitutes voltage stability does not yet exist. This is largely because distinctions between phenomena which represent different forms of instability are often subtle. Also, the physical aspects of voltage instability may not be well understood due to the complex nature of the phenomenon and the variety of ways in which it can manifest itself in power systems. Recently, due to advancement of power electronics technology, High Voltage Direct Current (HVDC) transmission technology has been utilized to enhance power system stability. The HVDC is very reliable, flexible and cost effective. Advances in artificial intelligence techniques such as Fuzzy, ANN etc. and Power Semiconductor devices have made tremendous impact in the improvement stability of HVDC system. A case is made to present overview of the artificial intelligence techniques possibility of including these techniques in modern power system and practices.
