In this paper, a stochastic framework for optimal sizing of a stand-alone hybrid energy system, including photovoltaic and wind turbine resources integrated with battery storage, is presented to meet an annual load while incorporating the uncertainties of resource production and load for 20 years of the project life. Monte Carlo simulation and K-means data clustering have been employed for uncertainty modeling and scenario reduction. The decision variables, such as system component sizes, are optimized using an improved arithmetic optimization algorithm (IAOA) to minimize the net present cost (NPC) and consider the reliability constraint as the probability of load supply inability (PLSI). The IAOA enhances the conventional arithmetic optimization algorithm (AOA) using Rosenbrock's direct rotational method to overcome premature convergence. Three configurations of the HES are evaluated: (Case I) a photovoltaic-battery system, (Case II) a wind turbine-battery system, and (Case III) a hybrid photovoltaic-wind turbine-battery system. Results show that Case III, with contributions from all renewable units and reserve energy management, provides the load with lower NPC and higher reliability than Case I and Case II. Additionally, the IAOA delivers the most effective solution, yielding the lowest NPC and PLSI compared to the conventional AOA. The stochastic sizing results indicate that incorporating uncertainty increases NPC and weakens reliability. Specifically, in stochastic sizing for Case III, the PLSI, cost of energy, and NPC were higher than the deterministic approach by 3.96 %, 5.17 %, and 9.15 %, respectively. The results demonstrate that the proposed stochastic sizing framework enhances the decision-making process for energy operators under uncertain conditions, providing insight into the system's costs and reliability.

Microgrids are usually referred to as small-scale producer that generates their power from renewable energy sources and distribute with maintaining high quality and fewer losses. Energy management is a critical aspect of microgrid operation, and different techniques can be applied to minimize operational costs and maximize the use of available sources. In this paper, we have developed an energy management system that includes a demand response and day ahead strategy to manage the load demand and power generation of renewable sources with the help of a deep learning method (T-LSTM) to reduce operational costs. In addition, a novel improved arithmetic optimization algorithm technique is applied to further optimize the system. In the demand response strategy, the microgrid operator involves consumers to reduce their electricity usage during periods of high demand or when electricity prices are high, either through direct communication or automated systems. The outcome of this study shows that the improved arithmetic optimization algorithm technique is effective in reducing operational costs by up to 13%. The findings of this research can assist in the development of efficient and cost-effective energy management systems for microgrids, which can help to improve the overall stability and sustainability of the energy infrastructure.

Unconfined compressive strength (UCS) is one of the rocks' most valuable mechanical properties in constructing an accurate geo-mechanical model. It has traditionally been determined through laboratory core sample testing or by analysis of well-log data. After a great deal of effort and growing investment in time, the proper adoption of machine learning methods, especially the radial basis function (RBF), opens a route to promising alternatives against empirical methods for better real-time prediction of UCS. The current study considers the RBF-based machine learning model, whose parameters have been optimized using two enhanced meta-heuristic frameworks: improved arithmetic optimization algorithm (IAOA) and Flying Foxes optimization (FFO). Based on an extensive dataset already used in previous studies and applying some soft computing techniques, vigorous performance metrics such as RMSE, R-2, MAE, U95, and MNB were used to test the developed frameworks. The outcomes indicate a significant outperformance of the hybrid RBFF technique over the solo RBF and RBF-IA frameworks. Specifically, the RBFF model resulted in an R-2 of 0.998, an RMSE of 1.313, and an MNB of -0.003, reflecting its better performance in UCS prediction. This study indicates the efficiency of integrating RBF with meta-heuristic optimization to enhance UCS predictions in geotechnical studies.

Integrating solar energy into the combined energy supply of surface water source heat pump systems is expected to reduce the electricity consumption and carbon emissions. In this paper, a solar-surface water source heat pump system model is established to maximize system performance and save economic cost. In order to find the optimal operation scheme, an improved arithmetic optimization algorithm (iAOA) is proposed. This algorithm integrates elite opposition-based and nonlinear acceleration functions to solve the model. The effectiveness of the proposed model and algorithm is verified by applying it to a SWSHP district energy system in the central area of Xiangtan city. Experimental results demonstrate that incorporating solar energy into the SWSHP district energy system can improve system performance and reduce operational costs. In comparison with several other optimization algorithms, this algorithm has a faster convergence speed and a higher convergence accuracy. Therefore, it is considered an effective method for solving solar-surface water source heat pump district energy systems.

The traditional FER techniques have provided higher recognition accuracy during FER, but the utilization of memory storage size of the model is high, which may degrade the performance of the FER. In order to address these challenges, an adaptive occlusion-aware FER technique is introduced. The occlusion is significantly detected by employing convolutional neural network (CNN). The face inpainting is accomplished via generative adversarial network (GAN). Lastly, the facial expressions are determined using the patch-based adaptive residual network with attention mechanism (PAResAM), where some hyperparameters are tuned optimally by using an improved arithmetic optimization algorithm (IAOA). The performance is evaluated and measured with diverse metrics. Thus, the outcome of the model ensures that it exploits a higher detection accuracy value.

Anomaly detection can improve the service level of the grid, effectively save human resources and reduce the operating cost of a power company. In this study, an improved arithmetic optimization-backpropagation (IAOA-BP) neural algorithm for an anomaly detection model was proposed for electricity inspection. The dynamic boundary strategy of the cosine control factor and the differential evolution operator are introduced into the arithmetic optimization algorithm (AOA) to obtain the improved arithmetic optimization algorithm (IAOA). The algorithm performance test proves that the IAOA has better solving ability and stability compared with the AOA, WOA, SCA, SOA and SSA. The IAOA was subsequently used to obtain the optimal weights and thresholds for BP. In the experimental phase, the proposed model is validated with electricity data provided by a power company. The results reveal that the overall determination accuracy using the IAOA-BP algorithm remains above 96%, and compared with other algorithms, the IAOA-BP has a higher accuracy and can meet the requirements grid supervision. The power load data anomaly detection model proposed in this study has some implications that might suggest how power companies can promote grid business model transformation, improve economic efficiency, enhance management and improve service quality.
