In order to improve the accuracy of the thermal error model of the electric spindle, a thermal error modeling method based on the optimized Elman neural network using the cuckoo algorithm is proposed. To analyze the thermal behavior of the electric spindle, an ANSYS analysis approach is utilized to create a temperature map. Based on the simulation analysis outcomes, an experimental platform is established to gather temperature data and thermal displacement data. The electric spindle temperature is optimized through the utilization of fuzzy cluster analysis and the Spearman rank correlation coefficient method in combination. The comparison between the established model and the Elman model and the GA-Elman model proves that the CS-Elman model has good prediction accuracy and stability.

To promote the development of green industries in the industrial park, a microgrid system consisting of wind power, photovoltaic, and hybrid energy storage (WT-PV-HES) was constructed. It effectively promotes the local consumption of wind and solar energy while reducing the burden on the grid infrastructure. In this study, the analytic hierarchy process (AHP) was used to decompose the multi-objective function into a single-objective function. The economic and environmental benefits of the system were taken as the objective function. Furthermore, the cuckoo search algorithm (CS) was used to solve the specific capacity of each distributed power source. Different scenarios were applied to study the specific capacity of microgrid systems. The results show that the equivalent annual cost of the WT-PV-HES microgrid system is reduced by 7.3 percent and 62.23 percent, respectively. The carbon disposal cost is reduced by 1.71 and 2.38 times, respectively. The carbon treatment cost is more sensitive to load changes. The solution iteration of the cuckoo algorithm is 18 times. Meanwhile, the system requires four updates of capacity allocation results for 20 years of operation. This result validates the effectiveness of the proposed model and methodology. It also provides a reference for the research and construction of capacity allocation of microgrid systems at the park level.

Fault detection technology based on parameter identification is advancing rapidly. For power electronic circuits, parameter identification is essential for accurately evaluating performance. The commonly used identification algorithms in engineering include least squares method and particle swarm optimization algorithm, etc. The least squares method has the disadvantage of large identification error and low identification accuracy, while the convergence instability and susceptibility to local optima of particle swarm optimization algorithm also need to be improved. To address the shortcomings of the least squares method and leverage the advantages of the cuckoo algorithm, such as strong global search capability and fast convergence, this paper focuses on the synchronous buck circuit. A local linear model of the synchronous buck circuit is established to mitigate the influence of nonlinear signals, and the signals collected include the terminal voltage VS2, inductor current iL and output voltage V0. The cuckoo algorithm is employed to identify the parameters. To overcome the local optimum problem associated with the cuckoo algorithm, an improved cuckoo algorithm is proposed that integrates simulated annealing to identify the parameters L, C, RL and RC in the circuit. To demonstrate the robustness and convergence of the proposed algorithm, we use the MATLAB/Simulink platform for comparative analysis against the conventional least squares method. The results show that the improved cuckoo algorithm achieves faster convergence and greater robustness. Finally, validation on a physical experimental platform indicates that the data extracted from the actual circuit maintains high identification accuracy and convergence speed, with identification errors below 5%, further verifying the effectiveness of the algorithm.

Adjustable mass dampers are widely used to reduce the seismic vibrations of engineering structures. The efficiency of these systems requires a proper setting of its parameters. In this study, an efficient and effective method for designing optimal multi-tuned mass dampers (MTMD) is proposed to reduce the vibration response of structures, which is based on the definition of a multi-objective optimization problem. Therefore, the multi-objective optimization algorithm of the cuckoo has been used to solve the issue. MTMD setting parameters are considered as design variables. Since the setting of MTMD parameters is basically a multi-objective optimization problem, three objective functions including minimizing the maximum displacement of the roof, the maximum acceleration of the roof and the maximum displacement of TMDs have been considered in the optimization problem. The results of numerical simulations for a ten-story shear frame exposed to an earthquake show that the cuckoo multi-objective optimization algorithm is able to find appropriate solutions in the form of Parreto curves to set the optimal parameters of MTMDs according to the design objectives. Provided that they are caused by creating a suitable compromise between the objective functions in conflict with each other. Therefore, MTMDs reduce the seismic responses of the structure in a favorable way. Based on the results, it was found that MTMD performance depends on incoming earthquake, TMD mass ratio and number of TMDs. By increasing the number of TMDs, up to a certain limit (10), the seismic response of the seismic system is reduced in a favorable way, but many changes in reducing the seismic response of the structure are not observed. Also, the seismic response of the system is reduced to a certain value (6%), by increasing the mass ratio of TMDs, but the process of reducing the seismic response of structures does not undergo many changes with its further increase.

In view of control issues associated with renewable energy hydrogen production systems, this study focuses on the hybrid hydrogen production system consisting of a photovoltaic-ALK+PEM electrolyzers and proposes a power control strategy based on the improved cuckoo algorithm. By implementing this control method in the DC-DC converters of electrolyzers, the system achieves stable operation and rapid convergence of DC bus voltage. Compared to PI control, the control scheme based on the improved cuckoo algorithm comprehensively enhances the system's performance, ensuring swift stability of DC bus voltage and precise control outcomes. This proposed method not only realizes coordinated control of multiple types of electrolyzers, but also considers the system's rapid response capability and anti-interference ability during the entire process.

With the development of microelectronics technology, the feature size of integrated circuit continues to shrink, and circuit performance has been improved. At the same time, however, factors such as process disturbance, power noise, and particle radiation are having an increasingly serious influence on the Failure Probability of Circuits (FPC). Searching the input vectors that are sensitive to FPC can assist circuit designers in selectively reinforcing the circuit to reduce the fault-tolerant overhead and improve the fault-tolerant efficiency. In this paper, an Improved Adaptive cuckoo Search (IACS) algorithm is proposed to search sensitive circuit vectors. The vector segmentation strategy is used to change the dimension of the input vector, the hill climbing algorithm is used to improve the quality of the initial population, and the adaptive strategy is used to control parameters such as power-law index, discovery probability and scaling factor. At the same time, a Correlation Separation Approach (COSEA) is proposed to calculate the FPC under specific vector excitation. Experimental results show that the proposed algorithm has higher accuracy and better efficiency compared with existing algorithms.

This study proposes the Sensor Device Scheduling-based cuckoo algorithm (SeDeSCA) for enhancing the lifespan of cluster-based WSNs. SeDeSCA consists of two phases: clustering and scheduling. The WSN is clustered into clusters using the DBSCAN algorithm in the first phase. The scheduling phase is periodic and consists of three steps: cluster head polling, scheduling decision-based optimisation, and covering. The sensors in each cluster choose their cluster head, which executes the cuckoo algorithm (CA) to select a suitable schedule of sensors that will achieve sensing during the current period. The aim of scheduling is to minimise energy consumption and ensure sufficient coverage for the monitored area while maximising network lifespan. The third step is to cover the area of interest with the sensors that are scheduled to be active during this period. The simulation results show that SeDeSCA improves the network lifespan and coverage ratio, as well as the lifespan of WSNs.

Energy storage technology can provide a variety of services for grid operation, such as peak regulation, frequency regulation, standby, startup, demand response, etc. However, considering that energy storage plants operate under multiple operating conditions, the peak regulation and valley filling of the power grid are unstable, and it is impossible to take into account the charging and discharging depth of energy storage plants and the decay of energy storage battery life and its capacity, so the original single charging and discharging control method can hardly meet the demand. The paper proposes an improved strategy of cuckoo algorithm for multiple operating conditions, and proves through experimental results that after considering the multi-operating conditions control strategy, the optimal configuration can be made by integrating all the operating conditions of the energy storage plant and the characteristics of the grid tide, which is superior to the actual operation of the original energy storage plant. © 2023 IEEE.
