An Adaptive Predictive Approach to Emergency Frequency Control in Electric Power Systems
Proceedings of the 44th IEEE Conference on Decision and Control, 2006Wide-area phasor measurements and modern communication techniques will provide access to system-wide frequency data with high accuracy and small time delay. This will make it possible also to monitor and control also relatively fast phenomena such as frequency instability using centralized approaches.

The Federal Reserve, the Emerging Markets, and Capital Controls: A High‐Frequency Empirical Investigation [PDF]
Journal of Money, Credit and Banking, 2012 In this paper, I use weekly data from seven emerging nations—four in Latin America and three in Asia—to investigate the extent to which changes in Fed policy interest rates have been transmitted into domestic short‐term interest rates during the 2000s.

The variable-speed doubly-fed wind turbines (DFIG) were able to participate in frequency regulation by adding an additional frequency control. The influences exerted by the additional frequency control of DFIG units and conventional units governors on system frequency emergency control measures were analyzed.

Low Frequency Oscillation Emergency Control Based on Wide-area Measurement
2018 International Conference on Power System Technology (POWERCON), 2018This paper presents a new method to suppress low frequency oscillation based on wide-area measurement. Since negative damping low frequency oscillation is usually caused by large disturbance that deteriorates system damping, relationships between oscillation modes and fault components are established through time-domain simulation.

Emergency Control Strategy of Ultra-low Frequency Oscillations Based on WAMS
2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2019In this paper, an emergency control strategy of ultra-low frequency oscillations (ULFO) is presented. The multi-signal Prony algorithm is used to identify frequency signals from WAMS. Then the criterion of ULFO is proposed based on the Prony analysis results.

Abstract The increasing penetration of renewable energy sources (RES) is transforming modern power systems by reducing system inertia and increasing vulnerability to frequency instability. In this context, microgrids (MGs), composed of distributed generators, energy storage systems, and controllable loads, have emerged as a promising ...

Abstract The effect of thermal plant response on system frequency control is investigated in the paper using the results of computer simulation studies. Particularly, when islanding conditions for loss of generation or loss of heavy import are involved, the frequency deviation is largely influenced by the prime mover energy supply system as well as ...
