Power quality enhancement between two adjacent feeders using whale optimized IDVR [articol]

Abstract

This paper proposes a novel control strategy based interline dynamic voltage restorer to improve the power quality between the two adjacent feeders in a distribution system. The interline dynamic voltage restorer is an interconnected form of multi dynamic voltage restorer with a common share of DC link. The artificial intelligence based control strategy is proposed here to achieve the faster rectification of the power quality issues such as voltage sag, voltage swell and harmonics. The whale optimization algorithm is proposed as the control strategy to accelerate the performance of the compensating unit towards the issues rectification. The architecture, control strategy and the performance are discussed in the paper. The effectiveness of the proposed whale optimized interline dynamic voltage restorer system is verified through the comparative analysis with the conventional optimization algorithms such as Ant Lion Optimizer and particle Swarm Optimization. The Fast Fourier transformation analysis for the harmonics rectification was discussed in the resultant part of the paper. The unabridged working of the proposed technique had implemented in Matlab/Simulink and verified.
