A hybrid method for energy management on grid-connected MG system is proposed under this manuscript. Grid-connected MG system takes photovoltaic (PV), wind turbine (WT), battery. The proposed system is an integration of seagull optimization algorithm (SOA) and the radial basic functional neural network (RBFNN), thus it is named SOA-RBFNN. Here, in the grid-connected microgrid configuration, the necessary load demand is always monitored with RBFNN methodology. SOA optimizes the perfect match of the MG taking into account the predictable load requirement. The fuel cost, together with the power variation per hour of the electric grid, the operation and maintenance cost of microgrid system linked with grid, is described. The proposed model runs on the MATLAB/Simulink workstation and efficiency is investigated using existing techniques as AGO-RNN and MBFA-ANN. Statistical analysis, elapsed time, modeling metrics, and determination of optimal sample size for adjustment and validation of proposed and existing technique are evaluated. The efficiency values on the 100, 200, 500, and 1000 trails are 99.7673%, 99.7609%, 99.9099%, and 99.9373%.

Micro particles have the potentials to be used for many medical purposes in-side the human body such as drug delivery and other operations. In the present paper, a novel hybrid algorithm based on Arithmetic optimizationalgorithm (AOA) and Artificial Gorilla troop's optimization (GTO), (HAOAGTO) is compared with different four algorithms Arithmetic optimizationalgorithm (AOA), Artificial Gorilla troop's optimization (GTO), seagull optimization algorithm (SOA), Parasitism-predation algorithm (PPA). These approaches were used to calculate the PID controller optimal indicators with the application of different functions, including Integral Absolute Error (IAE), Integral of Time Multiplied by Square Error (ITSE), Integral Square Time multiplied square Error (ISTES), Integral Square Error (ISE), Integral of Square Time multiplied by square Error (ISTSE), and Integral of Time multiplied by Absolute Error (ITAE). Every method of controlling was presented in a MATLAB Simulink numerical model. It is observed that the PPA technique achieves the highest values of best fitness value for simulation results among other control approaches, while the HAOAGTO approach reduces the best fitness function compared to other optimization techniques used. We verified that the obtained results by application of the proposed hybrid algorithm-based AOA and GTO (HAOAGTO) is better than those obtained by Arithmetic optimizationalgorithm (AOA), Artificial Gorilla troop's optimization (GTO), seagull optimization algorithm (SOA), Parasitism-predation algorithm (PPA). it is implemented to obtain the optimal parameters of the PID for reduction the ISTES.

Aiming at the issues of complex calculation and low accuracy of two-dimensional (2D) Otsu segmentation images, an image threshold segmentation means of 2D Otsu ground on a modified sparrow search algorithm is proposed. Firstly, in the initialization stage, the tent chaos mapping is added to enhance the multiformity of the population, and the population elite strategy is introduced to enhance the quality of the initial solution. Secondly, in the local search stage, the elite reverse learning strategy is applied to renewal the sparrow location to solve the issue of getting into local optimality. Eventually, the modified sparrow search algorithm is fused with 2D Otsu and the image threshold is segmented to enhance the accuracy of image segmentation. Compared with the traditional 2D Otsu algorithm, 2D Otsu genetic algorithm (GA-Otsu), 2D Otsu seagull optimization algorithm (SOA-Otsu), 2D Otsu particle swarm algorithm (PSO-Otsu) and 2D Otsu sparrow search algorithm (SSA-Otsu), the mean square error (MSE) value is reduced by 40.84%, 2.68%, 1.57%, 0.77% and 1.04%, respectively, and the peak signal-to-noise ratio (PSNR) value is increased by 24.48%, 1.24%, 0.83%, 0.40% and 0.45%, respectively. Moreover, the optimal threshold of the proposed algorithm is better than the other five algorithms. It is verified that the algorithm in this paper has faster convergence speed and higher accuracy, and effectively improves the quality of image segmentation.

Accurate prediction of bus arrival time is crucial for constructing smart cities and intelligent transportation systems. Objectivity and clarity must be maintained throughout to ensure efficient operation. Therefore, it is essential to achieve precise bus arrival time prediction. A recurrent neural network prediction model employing a dual-stage attention mechanism is proposed. The model was constructed based on bidirectional long and short-term memory networks, and arrival time predictions incorporate both dynamic and static factors of bus travel. The model utilized an advanced seagull optimization algorithm to optimize the model parameters, enhanced model iteration and population richness by incorporating the sine-cosine operator and adaptive parameters, and ultimately validated model performance through simulation experiments. The experimental results showed that the prediction error of the benchmark model is 324s and that of the normal peak is 87s. Considering the dynamic and static factors, the prediction error of the model was 6s similar to 8s. The minimum values of mean absolute percentage error, root mean square error and mean absolute error of the model were 0.07, 11.28 and 9.22, respectively. The experimental results demonstrated that the minimum error of the model exhibits the highest prediction accuracy, substantiating the model's potential for accurate prediction. Furthermore, the model's performance is effectively safeguarded from the impact of peak time. In addition, the model is feasible in practical application.

Positioning and anti-swing are the key issues of overhead crane control systems. An adaptive PID control strategy based on improved seagull optimization algorithm and neural network is proposed for overhead cranes under variable working conditions and disturbances. An adaptive PID controller based on a neural network is firstly designed to adjust parameters of the controller online. Then, an improved seagull optimization algorithm with an adaptive inertia coefficient is introduced to optimize the initial weight of the neural network. The optimization process of controller parameters and initial weights of neural network are given in the form of two algorithms. The results show that, compared with the adaptive PID control methods based on fuzzy rules and neural network technique with random initial weights, the proposed adaptive PID control strategy can make the crane system more adaptable to payload changes and more robust against disturbances. Additionally, compared with the particle swarm optimizationalgorithm, the improved seagull optimization algorithm makes the crane system more stable and has better positioning and anti-swing performance.

In recent years, as the Power Internet of Things continues to advance and improve, the routing requires efficient and reliable optimization methods to ensure stable operation. However, sensor nodes in Wireless Sensor Networks for Power Internet of Things have limited energy and lifespan, making the search for an efficient routing optimization method a critical issue. This paper innovatively proposes a novel high-reliable Wireless Sensor Networks routing optimization method for Power Internet of Things-the Multi-Objective Chaotic seagull optimization algorithm (MCSOA). MCSOA integrates chaotic optimization strategies with the seagull optimization algorithm, enable to escape local optima and improving its global search capability. Additionally, it incorporates multi-objective functions to address various key factors in PSWSN routing, including minimizing transmission loss, balancing load distribution, and enhancing system reliability. To evaluate the effectiveness of the optimization method, extensive new experiments were conducted, accurately reflecting real-world power grid operation scenarios. The experimental findings indicate that MCSOA significantly outperforms traditional algorithms like Genetic algorithm and Particle Swarm optimization in terms of efficiency. Specifically, MCSOA cuts down energy use by a minimum of 16.1% and prolongs the lifespan of the PSWSN by at least 15.6%.

Aiming at the problem that the traditional PID controller was not ideal, the parameters could not be adjusted to the best state, and the control system could not achieve good control effect, an improved seagull optimization algorithm (SOA) based on improved Sine chaotic mapping was proposed to optimize the parameters of PID controller. Sine mapping strategy was adopted to make the initial seagull population evenly distributed in the search space, to improve the shortcomings of the seagull optimization algorithm, such as low solution accuracy, slow convergence speed and easy to fall into premature convergence, and improve the convergence speed and convergence accuracy of the algorithm. Eight standard test functions were tested, and the improved gull optimizationalgorithm was compared with the unimproved gull algorithm, particle swarm optimizationalgorithm (PSO), beetle antennae search algorithm (BAS), particle swarm optimization -beetle antennae search algorithm (PSO-BAS) and the seeker optimizationalgorithm (TSOA), to verify that the improved gull optimizationalgorithm has better optimization effect. The improved algorithm is applied to a second-order system and double closed-loop DC motor speed regulation system to optimize the parameters of PID controller. The results show that the algorithm has high precision, simple principle, better convergence precision and faster convergence speed.

In this paper, fractional order PID (FOPID) optimized with seagull optimization algorithm (SOA) is designed as a secondary regulator for load frequency control (LFC) of the interconnected power system (IPS). However, the efficacy of FOPID is showcased with other integral order type classical controllers. IPS deliberated in this work is a widely used model of dual area hydro-thermal (DAHT) upon laying 10% perturbation of step load on area-1 (10%SLP) for investigation. Further, plug-in-electric vehicles (PEVs) are integrated into area-1 of DAHT for analysis purposes. DAHT responses are enhanced with the integration of PEVs. Later, the control areas of DAHT are incorporated with superconducting magnetic energy storage (SMES) devices to get further enhancement in system stability. Finally, simulation results reveal the superiority of implementing PEVs and SMES coordinated strategies for improvement in frequency regulation.
