Eliminating Selective Harmonics in Multi-level Inverters using Advanced Moth Flame Optimization Algorithm

Problem Definition

The current problem in the field of selectively eliminating specific harmonics lies in the limitations of the Sine Cosine Algorithm (SCA) when it comes to optimization precision and premature convergence. While SCA has garnered attention for its simplicity and ease of parameter tuning compared to other multi-agent-based optimization algorithms, it still struggles with getting trapped in local optima and is not well-suited for highly complex problems like the Selective Harmonic Elimination (SHE) problem. This presents a significant challenge for researchers and practitioners looking to enhance the quality of solutions in this domain. Given the constraints in the exploration and exploitation mechanism of traditional SCA, there is a pressing need for a novel approach that can effectively address the issues of premature convergence and low optimization precision. By overcoming these limitations, researchers can unlock new possibilities for improving the efficiency and effectiveness of selective harmonic elimination techniques.

Objective

The objective is to address the limitations of the Sine Cosine Algorithm (SCA) for selective harmonic elimination by implementing the advanced Moth Flame Optimization (MFO) algorithm. This new approach aims to overcome issues such as premature convergence and low optimization precision in order to improve the efficiency and effectiveness of selective harmonic elimination techniques in multilevel inverters. By leveraging the advantages of MFO, the project seeks to achieve optimal results in harmonic elimination, enhance the quality of solutions, and provide a more efficient method for addressing the challenges associated with achieving minimum harmonic distortion in these systems, ultimately leading to improved system performance and reliability.

Proposed Work

As mentioned in the problem definition, the existing methods for selective harmonic elimination in multilevel inverters have shortcomings such as low optimization precision and premature convergence. To address these issues, the proposed work aims to implement the advanced Moth Flame Optimization (MFO) algorithm. MFO leverages the behavior of moths converging towards light and has shown advantages over traditional algorithms in terms of exploration, local optima avoidance, exploitation, and convergence. By utilizing MFO, the goal is to update the optimal switching angle to minimize undesired harmonics effectively. By incorporating the advanced MFO algorithm into the project, it is expected to achieve optimal results in terms of harmonic elimination in multilevel inverters.

The superiority of MFO over other techniques lies in its strong search ability and ability to overcome the limitations of existing algorithms. This approach will not only enhance the quality of solutions but also provide a more efficient method for selective harmonic elimination. Through the utilization of MFO, the project aims to successfully resolve the challenges associated with achieving minimum harmonic distortion and effective harmonics elimination in multilevel inverters, ultimately leading to improved system performance and reliability.
