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.
