The common feature of many monitoring and control applications that will be accommodated in the future Wide Area Monitoring and Control system will be the quasi real time execution, exploiting the fast reporting rate of the Phasor Measurement Unit (PMU). A critical parameter for the timely execution and the good performance of such real time applications is the delay that the PMU measurements experience...
This paper explains the need of controller to detect the fast separation of phase angles among the critical areas automatically using synchrophasors and proceed to mitigate the instability by suitable switching action. Power systems are large interconnected nonlinear systems where system wide instabilities or collapses do occur over time. In that case, the system breaks up into many islands resulting...
In this work the implementation and real-time hardware-in-the-loop verification of a Hierarchical Agent-Based Voltage Instability Prevention (HABVIP) system are given. The basic control architecture attempts to restore a safe distance from the current power system operating point to the steady-state voltage stability limit. The control actions available to the HABVIP system are divided into three...
To prevent critical power system conditions dedicated out-of-step protection schemes are used in high-voltage networks, otherwise referred to as asynchronous operation protection automation. Structure of out-of-step automation is proposed in this paper addressing angular instability between multiple areas of the grid.
In this paper, we design a distributed dynamic feedback controller that implements real-time economic optimization in power networks with tree topology. We consider the coupling between the dynamics of the power network and the appropriately formulated optimization problem in the real-time market, i.e., when the time-scale separation between markets and network dynamics fades. The design methodology...
Oscillations have been observed in power systems from the moment networks comprising multiple generators were interconnected in order to provide more power capacity and reliability. They are typically poorly damped, however, not dangerous as long as they do not become unstable. An algorithm for fast real-time detection and stability assessment of dominant electromechanical oscillations utilising Kalman...
