Cascaded H-bridge multilevel inverters optimization using adaptive grey wolf optimizer with local search
No full textWith the transformation of transmission and distribution grids into smart grids that are more dominated by renewable energy, power electronics-based inverters that can improve power quality are becoming more visible. In order to maximize the output voltage quality and reduce the total harmonic distortion (THD), efficient operation of inverters is required. Therefore, in this paper, the problem of harmonic elimination in multilevel inverters is solved by using an adaptive grey wolf optimizer with local search. We have performed a grid search-based landscape analysis of the seven-level inverter to understand the behaviour of the proposed algorithm. For verification, the numerical results of the proposed adaptive grey wolf optimizer are compared with those of the original grey wolf optimization algorithm, a modified version of the grey wolf optimization algorithm, the particle swarm optimization algorithm, multi-verse optimization algorithm, and salp swarm algorithm. In the simulations, we solved the optimization model for three different structures of multilevel inverters (7, 11, and 15 levels) by changing the modulation indexes. It is found that the adaptive grey wolf optimization provides lower total harmonic distortion for different modulation indexes

Sur les basses surfaces de l'Ile de Ceylan (Lowlands topography in Sri Lanka)
No full textAbstracts. - The Western and Eastern lowlands of Ceylon, although characterized by the same lithological topics, reveal geomorphic features without any analogy. The study of those features do reveal a close relationship between the topography and the climate pattern, the island being divided in a wet and a dry zone.
The only doubtful point in this sequence is the stability of the climate in the past. The author emphasizes the fact that the monsoon contrast in South Asia should have been active since miocene times.Résumé. - Les basses surfaces de l'Ouest et de l'Est de Ceylan, de composition lithologique semblable, présentent des modelés fort différents. Ce contraste ne semble pouvoir s'expliquer que par une opposition climatique. Celle-ci aurait persisté depuis le Miocène.Louchet André.

Reinforcement of the distribution grids to improve the hosting capacity of distributed generation: Multi-objective framework
No full text© 2023 The Author(s)Excessive penetration of renewable energy resources into the distribution grid without additional preventive measures has led to several operational problems. However, most strategies developed to accommodate more renewable energy units suffered from other operational problems. Therefore, further efforts are needed to address the other key vulnerabilities of the grid in addition to maximizing the hosting capacity. In this regard, this study is devoted to a new multi-objective formulation to maximize the hosting capacity and minimize the total energy losses while satisfying the operational constraints and maximizing the energy transferred to off-peak hours. The Multi-Objective Advanced Gray Wolf Optimization (MOAGWO) algorithm is used as a solution tool. The proposed formulation and solution algorithm are tested on IEEE-33-bus and 69-bus medium voltage test systems. The impacts of energy storage systems, voltage regulators, and static var compensators on the hosting capacity and the objective functions are identified using several scenarios. The results showed that the optimal device type and locations depend on the level of DG penetration. Finally, a comparison according to two popular multi-objective performance indices showed that the quality of the Pareto front distribution obtained by MOAGWO was better than the ones obtained with the two other popular heuristic methods
Optimization of Multilevel Inverters Using Novelty-driven Multi-verse Optimization Algorithm
No full textAll over the world, renewable energy technologies which need power electronics based inverters in their designs are becoming more and more popular, thus detailed analysis to test the operational efficiency is required. This paper utilizes a new adaptive Multi-verse Optimization (MVO) Algorithm combined with novelty search method to solve harmonic elimination problem in multilevel inverters. We compare the obtained numerical simulations to those obtained by using the grey wolf optimization and standard MVO algorithm. The numerical simulations are performed on 7, 11, and 15 level inverters with different modulation indexes. From the simulation results, we observe that adaptive novelty search Multi-verse Optimization (MVO) based approach was able to obtain less total harmonic distortion for different modulation indexes.No Full Tex
