Abstract
Selective harmonics elimination (SHE) is a widely applied control strategy in multilvel inverters for harmonics reduction. SHE is designed for the elimination of low-order harmonics while keeping the fundamental component equal to any previously specified amplitude. This paper proposes a novel bio-inspired metaheuristic optimization algorithm called Black Widow Optimization Algorithm (BWOA) for solving the SHE set of equations. BWOA mimics the spiders’ different movement strategies for courtship-mating, guaranteeing the exploration and exploitation of the search space. The optimization results show the reliability of BWOA compared to the state-of-the-art metaheuristic algorithms and show competitive results as a microalgorithm, opening its future application for an on-line optimization calculation in low requirement hardware.
Highlights
Inverters are power electronics devices capable of providing an alternating output waveform from a direct current source at the required frequency and output voltage design specifications
The black widow optimization algorithm results are compared against the whale optimization (WOA) and modified grey wolf optimization (MGWOA) algorithms. e near-to optimal firing angles at 3 modulation index (0.6, 0.8, 1.0) are typically achieved by multilevel inverters, and their respective fitness and total harmonic distortion values are given in Tables 1–3, respectively
It can be seen that the values obtained from Black Widow Optimization Algorithm (BWOA) outperform the whale optimization algorithm (WOA) and MGWOA results regarding fitness and total harmonic distortion (THD) in all cases
Summary
Inverters are power electronics devices capable of providing an alternating output waveform from a direct current source at the required frequency and output voltage design specifications. Multilevel inverters (MLI) were first introduced midway during the seventies decade. Due to their versatility, they have been consistently applied as medium high voltage inverters, industrial drivers, and static VAR compensators, as well as for transmission and distributions systems, just to mention some [1, 2]. Even though there have been a few decades since they were initially developed, researchers are still designing new topologies and modulation strategies to improve the multilevel inverters’ performance, including, but not limited to, increasing their efficiency and to reduce harmonic content and electromagnetic interference (EMI) [3, 4]. Even though there have been a few decades since they were initially developed, researchers are still designing new topologies and modulation strategies to improve the multilevel inverters’ performance, including, but not limited to, increasing their efficiency and to reduce harmonic content and electromagnetic interference (EMI) [3, 4]. e best possible MLI performance arises from a combination of selecting a given topology and matching it with the right modulation strategy
