A Review on Hybrid AI-Based Control Strategies for Harmonic Reduction in Voltage Source Inverters Using CSA–RLS and Neural Network Techniques

Abstract

A major concern within electric power systems is the deterioration in power quality that arises from non-linear loads, as well as renewable energy. Harmonic distortions on electrical networks play a significant role in this process. Voltage Source Inverters (VSIs), largely used in modern power systems, need control strategies that should easily stabilise their highly efficient power outputs. This review paper is aimed at providing an in-depth examination of advanced techniques for harmonic elimination. The focus is on hybrid AI-based control. Traditional approaches such as the use of proportional-integral (PI) controllers and instantaneous p-q theory are still quite good but very poor in tracking a design to perform adaptively under uncertain and extreme dynamic scenarios. This article depicts an evolutionary narrative in intelligent control design with prominence given to the concept of incorporating optimisation and adaptive learning algorithms. Few of these include the Crow Search Algorithm (CSA) and Recursive Least Squares (RLS). It allows real-time parameter tuning so that the converging process can be accelerated, and the extraction of harmonics is robustened to aptitude by given methodologies. The hybrid control researchers have embedded the involvement of neural networks (NN) in it, as they memorise the behaviour of the system that is learnt in that way and thus approximate the optimised demand-switching strategies with VSI. Simulations are carried out in MATLAB/Simulink to gauge the efficacy of the new techniques for some key performance measures, such as THD, response time, and stability, in the given specific simulation based logical context. The study is fairly conclusive in showing that hybrid approaches are far superior to conventional approaches since the hybrid CSA–RLS–NN models have had a dramatic reduction in THD and overall improvement in power quality. Present trends, challenges, and future research directions relevant to intelligent harmonic control for the development of smart power systems—three very conducive areas for the next-generation smart power systems that can be taken care of using hybrid AI-based solutions.
