Power and Energy
Energy-storage-equipped static synchronous compensators (E-STATCOM) are crucial devices in a modern
power grid to regulate both the active and reactive power, thereby improving the efficiency and power
quality. Current controllers commonly used with E-STATCOM devices include proportional-integral (PI),
repetitive, and deadbeat controllers. However, each has application-dependent restrictions and therefore lack
the ability to achieve optimal operation. This paper presents a novel hybrid current controller that combines

This dataset includes corona discharge images under AC, + DC, and - DC voltages. To generate corona discharge, three types of electrodes were used. These are the conical rod - plane, the hemispherical rod - plane, and the hemispherical rod - hemispherical rod. One electrode was connected to the high voltage, and the other was connected to the ground potential. A digital single-lens reflex (DLSR) camera was used to capture corona discharge images from corona inception to the gap breakdown.

This paper presents the theory and key experimental findings for an investigation into the generation of bimodal resonance
(frequency splitting) phenomena in mutually over-coupled inductive sensors, and its exploitation to evaluate relative separation and
angular displacement between coils. This innovative measurement technique explores the bimodal resonant phenomena observed
between two coil designs - solenoid and planar coil geometries. The proposed sensors are evaluated against first-order analytical

The synthetic dataset was developed in the Power Electronics and Electrical Drive Laboratory (Laboratório de Eletrônica de Potência e Acionamento Elétrico – LEPAC, in portuguese) at the Federal University of Espírito Santo (UFES), Brazil. The dataset was generated from a computer simulation of a three-phase squirrel cage induction motor model with the insertion of faults in the rotor, specifically broken bars. The induction motor mathematical model with broken bar fault is based on reference [1].

An experimental study was conducted on a high-voltage glass-type disc (LD-160) to investigate the effect of string arrangements on pollution and icing flashover characteristics. Two Artificial Neural Network (ANN) applications were developed to simulate and calculate the flashover voltage based on the experimental results. The test results showed that the inverted T-type arrangement can improve the pollution flashover voltage and increase the icing flashover voltage of insulator strings compared to the traditional arrangement of the I-string.
