“…Moreover, an arrester explosion has happened during the black start of a 250 MW generation unit in the Iranian national grid [43], and also, the detailed electromagnetic simulation results presented in [44] (in which the nonlinear behavior of transformer core is modeled using three different models described in References [45][46][47]) show that the effect of transformer switching transients may result in the explosion of the arrester. erefore, effective countermeasures (such as controlled switching [48]) should be applied in order to control the overvoltages and keep the arrester safe.…”

More than thirty-six partial or whole blackouts, from 2016 to 2021, prove that neither the probability of blackouts can be ignored nor the required plans and the readiness of the utilities for power system restoration can be forgotten. To properly deal with blackouts and minimize the social and economic costs, utilities should prepare a suitable restoration plan in advance to quickly restore the system to the normal state and minimize the restoration time and loss of energy. In this paper, after summarizing major blackouts occurred from 2016 to 2021, the progress in the research reports, industrial documents, and books in the context of power system restoration is reviewed to show and classify the different aspects of power system restoration plans and strategies presented during these years. This review indicates that although there are many published methods and techniques which have tried to give more autonomous solutions, there are still more complexities in power system restoration. However, this paper respects all efforts and attempts and tries to illustrate the achievements, up to now, in power system restoration, as well as research gaps.

“…Energizing transformers can induce a significant non-sinusoidal inrush current, especially with residual flux, leading to mechanical stress, relay tripping, and voltage sags affecting power quality [ 28 , 29 , 30 , 31 ]. Resonance risks, causing temporary overvoltages (TOVs) and potential transformer winding failures, are explored in [ 32 , 33 , 34 ]. Ref.…”

This paper introduces an FPGA-based implementation of a smart switch designed to avoid inrush currents occurring during the connection of single-phase transformers utilized in grid-connected photovoltaic (PV) systems. The magnitude of inrush currents is notably impacted by the residual flux within the transformer core and the precise moment of energization relative to the wave cycle. Alternative methods frequently hinge on intricate procedures to estimate residual flux. This challenge is adeptly circumvented by the innovative smart control system proposed herein, rendering it a cost-effective solution for grid-connected PV systems. The proposed solution for mitigating inrush current remains effective, even in the face of challenges with current and voltage sensors. This resilience arises from the system’s ability to learn and adapt by leveraging information acquired from the network.
