this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

The low frequency electromechanical oscillations have been observed in many power systems and have resulted in system separation on several occasions. The main objective of this paper is to damp out the power angle oscillations of a two-area power system using Power System Stabilizers (PSSs) and Static Synchronous Series Compensator (SSSC) controllers. In this paper, the damping performances of...

Satisfactory damping of power oscillations is an important issue to be addressed when dealing with the angle stability of power systems. This phenomenon is well-known and observable especially when a fault occurs. To improve the damping of oscillations in power systems, supplementary control laws can be applied to existing devices. These supplementary actions are referred to as power oscillatio...

This research paper proposes a methodology to apply identification methods find simplified model of three different governors in single area electric power system (SAEPS). A SAEPS with governors-turbine is presented: hydraulic turbine, steam turbine and reheat turbine. In this same investigation, an analytic reduction has been performed, fifth order was found analytically, thus transfer functio...

A simple and computationally efficient decentralised control design method is introduced for load-frequency control (LFC) in interconnected power systems. The method is based on the use of a reduced-order observer and a proportional-plus-integral controller in each area of the power system, and ensures zero static change in area-frequency and tie-line power. Some of the features of the decentra...

43 ABSTRACT An optimal fuzzy AGC regulator design based on GASA tuning technique for interconnected power system is proposed in this paper. The investigations with the GASA tuned optimal fuzzy regulator are carried out on a two area interconnected power system consisting of power plants with different characteristics. Power system area-1 is having plants with reheat thermal turbines whereas are...
