The ever-increasing need for electricity in off-grid areas requires a safe and effective energy supply system. Considering the development of a sustainable energy system and the reduction of environmental pollution and energy cost per unit, this study focuses on the techno-economic study and optimal sizing of the solar, wind, biodiesel generator, and energy storage structure. The emerging metaheuristic optimization method is used to estimate the techno-economic benefits of the suggested structure to provide the required electricity for a residential household. The optimal design is done with the harmony search (HS) method to validate the results obtained with the suggested algorithm. Minimizing the total annual cost (TAC) is a main objective for the design optimization of the system while satisfying the reliability and techno-enviro-economic constraints. The impact of the investment cost of biodiesel, biofuel cost, and reliability is investigated on the system sizing. The results show that the proposed algorithm has low simulation time (by 4.1 %) and the operating cost of the proposed algorithm is 1.12 % less than the existing HS algorithm based on the best TAC value. The TAC is received as $24,259 with the suggested method, which is the best optimal result compared to the result given by the HS algorithm. The proposed off-grid renewable energy system based on a bio-diesel generator is a viable and scalable solution to provide the required electricity for a residential household in all periods. The sensitivity analysis show that if the biofuel cost is reduced by 50.8 %, TAC will decrease by about 36.6 %. On the other hand, if the bio-diesel generator cost is reduced by 17 %, TAC will be decreased by 2.7 %. Finally, if the limit value of reliability is reduced from 2 to 0 %, TAC will increase by 13.2 %.

As carriers of green energy, proton exchange membrane fuel cells (PEMFCs) and photovoltaic (PV) cells are complex and nonlinear multivariate systems. For simulation analysis, optimization control, efficacy prediction, and fault diagnosis, it is crucial to rapidly and accurately establish reliability modules and extract parameters from the system modules. This study employed three types of particle swarm optimization (PSO) algorithms to find the optimal parameters of two energy models by minimizing the sum squared errors (SSE) and roots mean squared errors (RMSE). The three algorithms are inertia weight PSO, constriction PSO, and momentum PSO. The obtained calculation results of these three algorithms were compared with those obtained using algorithms from other relevant studies. This study revealed that the use of momentum PSO enables rapid convergence (under 30 convergence times) and the most accurate modeling and yields the most stable parameter extraction (SSE of PEMFC is 2.0656, RMSE of PV cells is 8.839 center dot 10(-4)). In summary, momentum PSO is the algorithm that is most suitable for system parameter identification with multiple dimensions and complex modules.

DC-DC converters are an important area of power electronics. They have been used as the power converter interface for power point tracking in photovoltaic systems. The design of the optimized DC-DC converter thus is an important area for the research community. Design optimization of a DC-DC Buck, Boost, Synchronous Buck and Double Buck converters to reduce overall operational losses is the subject of investigation in this study. The ideal design requires selecting the most suitable values for circuit inductance, capacitance, and switching frequency to guarantee functioning in continuous conduction mode (CCM) and continuous voltage mode. The selected design constraints are the ripple content in voltage and current, and bandwidth for operation in CCM. A total of twenty eight (28) recently developed and popular existing metaheuristic optimization algorithms are utilized to select the optimized DC-DC converter's design. For identifying the best algorithm and to carry out a performance analysis established optimization algorithms like the Grey Wolf Optimizer (GWO), Moth Flame optimization algorithm , Particle Swarm optimization, Whale optimization algorithm (WOA) and Firefly algorithm are selected. The simulated results indicate that majority of algorithms are able to select the best design for the converter topologies within the selected constraint criterion's. The efficacy of an algorithm is determined based on statistical studies, convergence characteristics, computational time and robustness. It is noted that the algorithm that most effectively solves the current optimization problem is the WOA.

Grain stored for long periods is highly susceptible to localized condensation, mold growth, and insect infestations, leading to significant storage losses. These issues are particularly acute in large-capacity bungalow warehouses, where food security concerns are even more pronounced. The porosity of grain piles is a critical parameter that influences heat and moisture transfer within the grain mass, as well as the ventilation of grain storage. To investigate the distribution pattern of bulk grain pile porosity in bungalow warehouses, this study employs machine learning (ML) techniques to predict grain pile porosity based on compression experiments. Four metaheuristic optimization algorithms-particle swarm optimization (PSO), gray wolf optimizer (GWO), sine cosine algorithm (SCA), and tunicate swarm algorithm (TSA)-were introduced to enhance the random forest (RF) algorithm, and five ML-based models (RF, PSO-RF, GWO-RF, SCA-RF, and TSA-RF) for predicting grain porosity were developed. The predictive performance of the five models was analyzed using error analysis, Taylor diagrams, evaluation metrics, and multi-criteria assessments to identify the optimal ML prediction model. The results indicate that the predictive performance of the four RF-based hybrid models surpasses that of the single RF model. Among these hybrid models, the TSA-RF model demonstrated the best predictive performance, achieving R2 values of 0.9923 in the training set and 0.9723 in the test set. The TSA-RF model was employed to conduct a hierarchical prediction of bulk grain pile porosity in the bungalow warehouse. The results indicate that the porosity of the grain pile exhibits a pattern of being higher in the middle and smaller at the edges as the depth of the grain pile increases. The TSA-RF model developed in this study offers a novel and efficient method for predicting grain porosity, enabling rapid assessments of porosity in bulk grain piles within the bungalow warehouse.

An accurate analysis of wind speeds is vital to justify wind energy projects. Statistical distributions can be used to characterize wind speeds through considering uncertainty in wind resources. However, the selection of the most suitable probability density function (PDF) is still a challenging task. Therefore, this study aims at developing a framework to accurately evaluate the performance of different PDFs to fit wind speeds, as well as presenting a new metaheuristic optimization algorithm method, called Social Spider optimization (SSO), for wind characterization purposes. Seven sites in Saudi Arabia are used as case studies. Results indicate that combined PDFs outperform single PDFs in representing the observed wind speeds frequencies at all considered sites. Weibull distribution appears to be the most prevalent single distribution while no combined PDF dominates the others. In addition, the proposed SSO method is found to be the most efficient method for estimating PDFs parameters in Saudi Arabia. Overall, this proposed framework can be used to evaluate different wind PDFs in other countries. (C) 2019 Elsevier Ltd. All rights reserved.

Multilevel inverters (MLIs) are one of the most popular topics of power electronics. Selective harmonic elimination (SHE) method is used to eliminate low-order harmonics in the MLI output voltage by determining the optimum switching angles. It includes the solution of nonlinear sets of transcendental equations. The optimization becomes more difficult as the number of levels in MLIs increases. Therefore, various metaheuristic algorithms have emerged toward obtaining optimal solutions to find the switching angles in the SHE problem in the last decade. In this study, a number of recent metaheuristics, such as ant lion optimization (ALO), hummingbird algorithm (AHA), dragonfly algorithm (DA), harris hawk optimization, moth flame optimizer (MFO), sine cosine algorithm (SCA), flow direction algorithm (FDA), equilibrium optimizer (EO), atom search optimization, artificial electric field algorithm and arithmetic optimization algorithm (AOA), are employed as an attempt to find the best optimization framework to identify switching moments in 11-level MLI. Marine predator algorithm (MPA), whale optimization algorithm (WOA), grey wolf optimizer (GWO), particle swarm optimization (PSO), multiverse optimizer (MVO), teaching-learning-based optimization (TLBO), and genetic algorithm (GA), which are widely used in solving this problem, are selected for performance analysis. AHA, ALO, AOA, DA, EO, FDA, GA, GWO, MFO, MPA, MVO, PSO, SCA, SSA, TLBO and WOA methods meet maximum 8% THD requirement specified in IEEE 519 standard in the range of 0.4-0.9 modulation index. Simulation results show that MFO is superior other algorithms in terms of THD minimization, convergence rate, a single iteration time and robustness.

This work explores the deployment of renewable based energy systems considering solar panels, wind turbines and battery energy storage for the charging of Plug-in Electric Vehicles (PEVs) in the Noida region. The main concern of this article is to establish the optimal sizing of system components in order to reduce energy costs and the possibility of power outages. To accomplish these goals, this research employs a unique metaheuristic-based optimization strategy known as the Giza Pyramid Construction technique (GPCA). The superiority of the solution provided by the GPCA is proven by comparing the results obtained using Grey Wolf optimization (GWO), Flower Pollination algorithm (FPA), Salp Swarm algorithm (SSA) and Moth Flame optimization (MFO). The algorithms used in the study are simulated 50 times with various values of loss of power supply probability (LPSP) such as 0 %, 1 %, 3 %, and 5 %. The simulation results show that the GPCA achieves the desired objectives with high accuracy and resilience. The study also examined how varying grid tariffs influenced the levelized cost of energy. The findings revealed that, when compared to other options, the solar/wind/battery combination had a significantly lower levelized cost of energy and overall net present cost. The total net present cost estimated by GPCA is lower by 7.9 %, 14.1 %, 17.9 %, and 24.5 % compared to the costs calculated using GWO, MFO, SSA, and FPA, respectively. Similarly, the GPCA provides optimized value of LCOE (0.3697 $/kWh) which is 3.1 %, 7.3 %, 8.8 % and 11.5 % less than GWO, MFO, SSA and FPA respectively. The outcomes of this research will provide valuable insights for researchers aiming to determine the most effective strategy for powering PEV charging through a multi-energy system approach. This information can be beneficial for other cities seeking to establish a similar strategy. The proposed system holds the potential to reduce dependence on overloaded grids, especially in developing citie

The growing competitiveness of the chemical industry, along with sustainability demands and regulatory requirements, calls for optimized and well-controlled operations. Chemical engineering processes are often characterized by non-linearity, strong variable coupling, dead times, multiple inputs and outputs, and operational constraints, making control strategies challenging. Model predictive control is widely used for its advantages in optimal control, flexibility, robustness, and ability to handle multi-objective tasks. However, precise tuning and optimization are essential for implementing this strategy in real-time applications. metaheuristic optimization algorithms offer an alternative to traditional optimization methods, as they can quickly reach near-optimal solutions and avoid local minima, making them well-suited for use with model predictive control. This study aims to analyze the application of metaheuristic optimization algorithms in conjunction with model predictive control in chemical engineering processes through a systematic review. The review considers three eligibility criteria: applying model predictive control for process control, utilizing metaheuristic optimization algorithm, and chemical engineering-related processes. A total of 46 studies were analyzed, revealing three main application areas for metaheuristic optimization algorithms in model predictive control: improving dynamic models used in the receding horizon, tuning model predictive control parameters, and serving as optimizers in the model predictive control formulation. Over 20 different metaheuristic optimization algorithms and various process models were identified, with typical applications including continuous stirred tank reactors, tank-level control, and column distillation. Genetic algorithms and particle swarm optimization were the most frequently used algorithms. This review concludes that metaheuristic optimization algorithms have been successfully applied to enhance model pre

optimization algorithms have been employed for a variety of applications such as engineering design optimization, machine learning, control systems, computer science and software engineering. Among various optimization approaches, nature-inspired metaheuristic optimization algorithms excel in addressing complex optimization problems by considering various constraints and optimizing a wide array of variables and target functions. In finite-difference time-domain (FDTD) methods for complex dispersive media, it is crucial to derive accurate dispersion model parameters that satisfy the numerical stability conditions by applying an optimization algorithm. In this work, we apply five representative nature-inspired metaheuristic optimization algorithms to extract accurate and numerically stable dispersion modeling parameters: continuous genetic algorithm, particle swarm optimization (PSO), artificial bee colony, grey wolf optimization, and coyote optimization algorithm. To achieve a comprehensive analysis, this study examines the FDTD dispersion modeling for various materials across different frequency ranges. The numerical examples illustrate that PSO excels at extracting numerically stable and highly accurate parameters for the FDTD dispersion model.
