Analysis of Energy Controllers for Enhancement of Energy Flow

The fast changing energy market has brought the new challenges in the field of transmission systems. Today’s energy transmissionnetworks are not designed for easy voltage flow in a deregulated market and steady state control problems as well as dynamic problem are theresult. A new technology in this field, the flexible ac transmission system is gaining popularity in the world due to its enormous advantages. This paper gives an overview of its development; briefly describes its device and explains its effects. Furthermore, because of the tremendousinfluence on the system by the introduction of flexible ac transmission system, there is a great demand to improve the energy system analysis. Also, this paper present some aspects and direction needed to be studied
