TL;DR: In this article, a fast unblocking scheme for distance protection to identify symmetrical faults occurring during power swings has been proposed, where the change rate of three-phase active power and reactive power being the cosine function and the sine function with respect to the phase difference between the two power systems during power swing has been demonstrated.

TL;DR: Based on the improved optimization objective function of fault diagnosis, a genetic algorithm-Tabu search (GATS) method is introduced for fault diagnosis of power systems in this paper, where the results of case studies show that GATS is superior to conventional methods in terms of the sensitivity of original solution and the dependency of original parameters.

TL;DR: In this article, a load density method is introduced to determine the optimal capacity of the EV charging stations in the areas to be planned, and the difference between 1 and the weight coefficients obtained by the analytic hierarchy process (AHP) method is used to calculate the cost coefficients of the charging station.

TL;DR: A local measurement-based ultra-high-speed main protection is proposed, which has satisfactory performance against internal faults and is quite reliable in external fault and operating condition changes.

TL;DR: The worst condition for the correct action of this criterion is presumed and proven, leading to the invention of novel distance protection which can operate rapidly during power swings, and complete self-adaptive distance protection is put forward.
