In this paper, a novel nonlinear robust damping controller is proposed to suppress power oscillation in interconnected power systems. The proposed power oscillation damping controller exhibits good nonlinearity and robustness. It can consider the strong nonlinearity of power oscillation and uncertainty of its model. First, through differential homeomorphic mapping, a mathematical model of the s...

This paper is concentrated mainly to the cause and to clear the Power Swings in synchronous generator due to rotor speed oscillations in wind farm which is a distributed generation to maintain the stability of rotor oscillations. The paper presents different conditions of disturbances and faults in specified time period. In Power System Damping Oscillation modes are excited due to disturbance i...

This letter proposes an analytical approach to formulate the power system oscillation frequency under a large disturbance. A fact is revealed that the oscillation frequency is only the function of the oscillation amplitude when the system’s model and operating condition are fixed. Case studies also show that this function is damping-insensitive and could be applied to an inter-area model of a m...

Series compensators have been used for many years, to increase the stability and load ability of transmission line. They compensate retarded or advanced volt drop of transmission lines by placing advanced or retarded voltage in series with them to compensate the effective reactance, which cause to increase load ability of transmission lines. In this paper, two method of fuzzy controller, based ...
