TL;DR: In this paper, a small-signal model of interconnected system with DIF integration considering PLL and virtual inertial control is established, and attenuation time constants of DFIG state variables are calculated, and according to the attenuation speeds of different state variables and the coupling between them, the main factors that affect the coupling of DIF and synchronous generators are found out.

TL;DR: In this article, an adaptive current protection scheme is proposed for the protection of power systems with penetration of distributed generation (DG), where the steady state fault current of the related power transmission lines is derived from steady state network equivalent reduction.

TL;DR: A novel wide area backup protection algorithm to identify fault branch based on the fault steady state component is proposed and the simulation results for the 10-generator 39-bus system verify that this method is able to easily identify fault Branch with limited measurement points.

TL;DR: In this article, a method to resolve fault localization problems in power system was developed based on real-time measurement of phasor measurement units, which used mainly pattern classification technology and linear discrimination principle of pattern recognition theory to search for laws of electrical quantity marked changes.

TL;DR: In this paper, the application of phasor measurement unit (PMU) measurements and adaptive wide-area damping control based on federated Kalman filters is investigated, where the Kalman filter used for estimating the operating conditions are federated using chi-square variables and a confidence interval.
