The oscillatory stability of the system is becoming a vital problem to be taken into consideration in modern interconnected power systems operation. The information about poorly damped modes and their source should be known to the operator in real time to apply any control actions. But the conventional methods are usually time consuming and offline. In this paper, an intelligent Wide Area Measurement...
Power system oscillation monitoring and control in real-time is an important issue to be taken into consideration in modern interconnected power systems operation. This paper proposes a method to find the system damping and identification of coherent groups in the system following a disturbance in real-time using Artificial Neural Network. The first four cycles of post disturbance data comprising...
This paper demonstrates synthesis of a robust wide-area controller for damping inter-area power system oscillation. A wide-area damping controller is more effective in damping inter-area modes in power system as it takes remote signal as feedback in which inter-area oscillations strongly observable. However, with the involvement of remote signal time-delay is introduced in the feedback loop causing...
Power system oscillations monitoring is a vital issue in operation of modern interconnected power systems. The existing methods for identifying the electromechanical modes are time-consuming and require modelling of the entire system that includes a large number of states and are performed offline. In this paper, an integrated Phasor Measurement Unit and Artificial Neural Network (PMU-ANN) based approach...
In a modern power system, damping of an inter-area mode is crucial as it limits the power transfer capability. With the progress in Wide-Area Measurement System (WAMS), now dynamic data from wide geographical areas are available readily. The accuracy of such data motivates to be used as feedback for controllers, which can have better performance. The placement of such controllers and the signals to...
