To solve the problem of falling into local optima and slow convergence speed in the standard kepler optimization algorithm, the improved kepler optimization algorithm is proposed. Firstly, the random number generator is replaced by the circle mapping and reverse learning strategy in the initial population stage. Secondly, the introduction of adaptive mutation rate and arctangent decay factor in the stage that planets update positions, which adjust the search space of the algorithm in the early and late stages, improves the convergence speed of the algorithm. Thirdly, Gauss mutation is performed on the position of the optimal solution to improve the algorithm's tendency to fall into local optima. Finally, improved kepler optimization algorithm, and four other optimization algorithms, are comprehensively tested on 8 benchmark functions. The experimental results show that the proposed algorithm has higher convergence speed and accuracy.

Liver diseases represent a significant healthcare challenge, impacting millions globally and posing complexities in diagnosis. To address this global health concern, this paper introduces a groundbreaking enhancement to the kepler optimization algorithm, termed I-KOA, designed specifically for feature selection in high -dimensional datasets. By harnessing the synergies of Opposition -Based Learning and a Local Escaping Operator grounded in the k -nearest Neighbor (kNN) classifier, I-KOA asserts itself as a potent tool for local exploitation, balanced exploration, and evasion of local optima. To our knowledge, this is the first work to exploit KOA as a feature selection method. Pioneering the utilization of KOA as a feature selection method, the paper rigorously tests I-KOA in two extensive experiments, tackling the complex CEC'22 benchmark suite functions and the intricate landscape of five liver disease datasets. Results underscore I-KOA's unparalleled performance, validated through the Friedman test, where it surpasses seven rival optimization algorithms. Achieving an outstanding overall classification accuracy of 93.46%, Feature selection size of 0.1042, sensitivity of 97.46%, precision of 94.37%, and F1 -score of 90.35% across the liver disease datasets, I-KOA's randomized algorithm ensures robust feature selection, striking a compelling balance between subset size and classification efficacy. Acknowledging computational demands and generalization nuances, I-KOA is a formidable tool ready to revolutionize medical diagnosis and decision support systems.

The primary objective of this study is to investigate the effects of the Fractional Order kepler optimization algorithm (FO-KOA) on photovoltaic (PV) module feature identification in solar systems. Leveraging the strengths of the original KOA, FO-KOA introduces fractional order elements and a Local Escaping Approach (LEA) to enhance search efficiency and prevent premature convergence. The FO element provides effective information and past expertise sharing amongst the participants to avoid premature converging. Additionally, LEA is incorporated to boost the search procedure by evading local optimization. The single-diode-model (SDM) and Doublediode-model (DDM) are two different equivalent circuits that are used for obtaining the unidentified parameters of the PV. Applied to KC-200, Ultra-Power-85, and SP-70 PV modules, FOKOA is compared to the original KOA technique and contemporary algorithms. Simulation results demonstrate FO-KOA's remarkable average improvement rates, showcasing its significant advantages and robustness over earlier reported methods. The proposed FO-KOA demonstrates exceptional performance, outperforming existing algorithms by 94.42 %-99.73 % in optimizing PV cell parameter extraction, particularly for the KC200GT module, showcasing consistent superiority and robustness. Also, the proposed FO-KOA is validated of on SDM and DDM for the well-known RTC France PV cell.

The flexibility and intermittency of wind speed is a crucial factor for its prediction. Research in this domain necessitates integrating diverse data to enhance model precision and reliability to meet the growing demand for wind energy in both the energy sector and the global economy. To this end, this work adopts the kepler optimization algorithm (KOA), which utilizes the position of each planet as a candidate solution. The optimization process then involves random updates to these candidate solutions, aiming to enhance wind speed prediction using the CNN-LSTM-Attention model. Specifically, it enhances the interpretability of the KOA for the global optimization problem. By using 1800 time moments of wind speed data with multidimensional features, the proposed hybrid model with KOA has been shown to outperform other optimization methods, demonstrating impressive performances in terms of mean absolute percentage error (MAPE), mean absolute error (MAE), runtime, root mean square error (RMSE), and R2. 2 . Hence, these results indicate its potential for improving wind speed prediction, which could open a novel direction in this field.

Internet enterprises, as the representative enterprises of technology-based enterprises, contribute more and more to the growth of the world economy. To ensure the sustainable development of enterprises, it is necessary to predict the risks in the operation of Internet enterprises. An accurate risk prediction model can not only safeguard the interests of enterprises but also provide certain references for investors. Therefore, this study designed a Convolutional Neural Network (CNN) model based on the kepler optimization algorithm (KOA) for risk prediction of Internet enterprises, aiming to maximize the accuracy of the prediction model, and to help Internet enterprises carry out risk management. Firstly, we select the indicators related to the financial risk of Internet enterprises, and predict the risk based on the traditional statistical analysis of Logistic regression model. On this basis, KOA was improved based on evolutionary strategies and fish foraging strategies, and the improved algorithm was applied to optimize CNN. Based on improved KOA and CNN algorithms, an IKOA-CNN risk prediction model is proposed. Finally, by comparing traditional statistical analysis-based models and other learning-based models, the results show that the IKOA-CNN algorithm proposed in this study has the highest prediction accuracy.

Growth in electricity grids, environmental awareness, and power reliability requirements necessitate the development of solutions for single- and multi-objective Optimal Power Flow (OPF) problems, emphasizing the need for effective optimization algorithms. In literature, both classical optimization techniques and metaheuristic algorithm-based methods have been proposed to solve the OPF problem. Studies are typically conducted on the test systems. Additionally, the applicability of these methods to real systems is also of great importance. In this study, the kepler optimization algorithm (KOA), was applied to solve the OPF problem not only on test systems but also, for the first time in the literature, on a real system operating in island mode to determine its optimal operating points. First, KOA's performance was evaluated for various objective functions on the IEEE 30, IEEE 57, and IEEE 118 bus test systems. Using the KOA, results were obtained for single- and multi-objective functions, including fuel cost, active power loss, emission, and voltage deviation, either individually or all together. The same objective functions were also solved using the Golf optimization algorithm (GOA) and Whale optimization algorithm (WOA) using the population and iteration parameters, and the results were compared with those obtained using KOA. KOA demonstrated superior performance compared to GOA and WOA in all objective functions across the three test systems. Additionally, the results were compared with other numerous methods proposed in the literature to assess KOA's performance. The findings indicated that KOA obtained better performance in most of the objective functions. Finally, the KOA was used on a real 22-bus system operating in island mode to evaluate its performance. For this real system, results of 6563.724 $/h fuel cost, 0.1283 MW active power loss, and 0.0498 p.u. voltage deviation were obtained, indicating that KOA could be effectively utilized in real systems. © 20

Identification of photovoltaic (PV) module characteristics in solar systems is a vital task, nowadays, for optimal PV power estimation. In this paper, this challenge task has been studied using a novel advanced kepler optimization algorithm (KOA). The standard version of KOA is adopted and assessed for getting the nine parameters of the PV triple diode model (3DM) considering three different practical PV modules. kepler's principles of planetary motion are used by KOA to forecast the location and velocity of planets at any particular moment. However, the success rate of the KOA is not compatible, and its efficiency needs to be enhanced. As a result, an Improved KOA (IKOA) is created by incorporating an advanced mechanism of Local Escaping Operator (LEO), resulting in improved process of searching with evading local optima. This mechanism means that the exploitation approach will activate with around half of the solutions for every iteration starting at the initial phase of the iteration journey. The suggested IKOA besides the standard KOA are developed for predicting PV parameters for three distinct PV modules which are Photowatt PWP201, R.T.C France and STM6-40/36. The results corresponding to the latest algorithms are also compared with the proposed IKOA about different published works. The simulation findings reveal that the suggested IKOA exhibits notable average improvement rates for the three modules of 62.27 %, 55.1 %, and 32.12 %, respectively. Furthermore, the suggested IKOA asserts significant superiority and robustness over previously reported results. © 2024

The incorporation of plug-in hybrid electric vehicles (PHEVs) offers a promising solution to tackle the energy crisis while reducing environmental challenges. With enhanced control and storage features, PHEVs contribute to greater flexibility in distribution networks. However, managing these vehicles alongside renewable energy sources (RES) presents significant challenges. This study proposes a novel Energy Management Strategy (EMS) for microgrids (MGs) integrating RES and PHEVs. The MG includes wind turbines (WT), photovoltaic panels (PV), micro turbines (MT), fuel cells (FC), storage batteries, PHEVs, and the grid. The primary objective is to minimize operational costs and environmental emissions, framed as an optimization problem. The EMS considers two RES operation scenarios and three electric vehicle (EV) charging mod- es-uncoordinated, coordinated, and smart-while addressing uncertainties in renewable energy generation and load demand considering the demand response program (DRP). It also in- corporates demand response mechanisms for greater resilience. The kepler optimization Algo- rithm (KOA), inspired by kepler's laws of planetary motion, is employed to tackle the nonlinear optimization problem. KOA models candidate solutions as planetary positions, continuously updating them relative to the optimal solution for comprehensive domain exploration. Simulation results reveal substantial improvements in cost and emission reductions. Without PHEVs, KOA achieves a mean operating cost of 109.623 ct, 1.46 % lower than benchmark methods, with minimal variability (standard deviation: 0.0002 ct). For maximum RES generation, costs are further reduced to 86.2143 ct with consistent performance (standard deviation: 0.0001 ct). When PHEVs are included, KOA demonstrates cost reductions of up to 17.9 % across various charging modes, showcasing its adaptability and efficiency in dynamic energy systems.

Due to the uncertainty of meteorological factors and the influence of human activities, the monthly runoff series often exhibit the characteristics of non-stationarity. The appropriate prediction model and the hyperparameters of the model are often difficult to determine, and this affects the model prediction performance. For obtaining the accurate runoff prediction results, a novel prediction model (KVMD-KTCN-LSTM-SA) is proposed. This hybrid model uses kepler optimization algorithm (KOA)-optimized Variable Mode Decomposition (KVMD), KOA-optimized temporal convolutional network-long short-term memory (TCN-LSTM), and the self-attention (SA) mechanism. KVMD effectively reduces the difficulty of predicting the monthly runoff series, KOA helps to find the optimal hyperparameters of the model, TCN is combined with LSTM, and the SA mechanism effectively increases the performance of the model. Monthly runoff from three hydrological stations in the Hetian River basin and one hydrological station in the Huaihe River basin are predicted with the proposed model, and six models are selected for comparison. The KVMD-KTCN-LSTM-SA model effectively reduces runoff fluctuation and combines the advantages of multiple models and achieves satisfactory runoff prediction results. During the testing period, the proposed model achieves NSE of 0.978 and R2 of 0.982 at Wuluwati station, NSE of 0.975 and R2 of 0.986 at Tongguziluoke station, and NSE of 0.978 and R2 of 0.982 at Jiangjiaji station. The proposed hybrid model provides a new approach for monthly runoff prediction, which is capable of better managing and predicting mid-long-term runoff.

This paper presents a novel breast tumor identification strategy utilizing microwave imaging technology with specially designed antennas. The aim is to address the complexities arising from heterogeneity of breast tissues, which pose challenges for conventional breast cancer detection methods. To overcome these challenges, an Antipodal Vivaldi antenna (AVA) is developed, featuring dimensions of 53.07 x 46.07 x 0.6 mm(3). The design parameters of AVA are optimized using mutation boosted kepler optimization algorithm (MBKOA). Specific Absorption Rate (SAR) analysis on phantom breast with tumors is carried out utilizing finite-difference time-domain (FDTD) approach. To enhance signal strength at desired imaging location, Microwave Imaging beamforming algorithm is applied. Fast Delay Multiply and Sum (DMS) based image reconstruction algorithm is employed on time-domain data, providing high spatial response and comprehensive representation of internal structure of the breast.
