Real-time transmission line switching control is a cost-effective and efficient measure to alleviate line overload. However, due to the nonlinear characteristics of the transmission network structure optimization problem, conventional optimization methods often struggle to find solutions quickly. In recent years, data-driven methods have been widely applied in fields such as power system dispatch optimization. This paper proposes a method based on deep neural networks. By using historical and simulation data of the power system, the neural network is trained to perform exploratory learning and find optimal topology control strategies when line overload occurs. This method is trained and tested on the IEEE 14-bus open-source dataset, and the test results verify its effectiveness.

Distributed systems are critical infrastructures for many enterprises and organizations, yet they also present challenges in fault diagnosis. To improve the efficiency and accuracy of fault diagnosis in distributed systems, this paper proposes a fault diagnosis model based on the RF-LGBM algorithm. The model first utilizes LGBM for initial diagnosis and then employs RF to reclassify the two fault types with lower accuracy. The results indicate that the RF-LGBM model achieves an AUC greater than 0.96, effectively diagnosing faults in distributed systems.

Morphing vehicles achieve optimal flight performance by changing shape under different flight conditions and missions to meet different mission requirements. In this paper, the variable span vehicle is studied, and the status-deformation cooperative control of the morphing vehicle is developed. The structural deformation of the vehicle is treated as the control input, and the status-deformation cooperative control model is established. Then, a virtual adaptive sliding mode control law is designed and assigned to the actual control inputs by solving the optimization problem. Simulations show that the control algorithm achieves status-deformation cooperative control, Compared to conventional vehicles, morphing vehicle can achieve desired cost function optimization by actively changing the wingspan at different flight phases, reducing fuel or rudder deflection requirements.

This paper proposes a control parameter setting method for AVC systems that considers the mutual interference of device actions. This method first divides the setting periods of each set of VQC control parameters based on the results of reactive power optimization, and determines the adjustment amount of equipment during each action setting period. Then, combined with the fifteen zone diagram control strategy, considering the possible monitored states and certain margin values of the system caused by different action sequences of other devices before equipment action, the AVC system control parameters considering mutual interference of equipment actions and load curve errors are set to ensure that the control equipment can act according to the strategy obtained from dynamic reactive power optimization. This method has been applied in the 35kV Qieji substation, which has effectively improved voltage quality and reduced the number of transformer tap actions. It has good practical value and application effects.

According to the advantages and disadvantages of the existing maximum power point tracking methods, this paper proposes a new maximum power point tracking method by applying the fuzzy control to the gravitational search algorithm, firstly, improve the optimization speed by taking advantage of the fast convergence speed of the gravitational search algorithm, and secondly, set the index of population maturity, and then set the dynamic adjustment strategy for the flight speed of the particles in the solution space by introducing the fuzzy rule after the population reaches a certain maturity level. After the population reaches a certain maturity, by introducing fuzzy rules, the dynamic adjustment strategy of particle flight speed in the solution space is set up. Finally, a simulation model is established by MATLAB/simulink, and simulation analysis is carried out under different lighting environments, and compared with the traditional gravitational search algorithm, which proves the advantages of the improved algorithm in terms of the searching accuracy and speed, as well as a better effect in solving the problem of local optimization.

The construction of a large power grid planning and operation platform requires the integration and organization of multi-source heterogeneous data. However, the various types of power grid business have differing levels of importance and high demands for timely response, which current data organization methods struggle to meet. This paper proposes an ontology-based optimization method for multi-source heterogeneous data organization in large power grid planning and operation platforms. A mathematical optimization model is constructed, taking into account both business retrieval efficiency and data redundancy. Additionally, the genetic algorithm is improved based on the specific characteristics of this optimization problem. The method proposed in this paper is then applied to integrate data from multiple power software applications. Experimental results show that this method effectively balances data retrieval efficiency and storage space utilization, achieving automated organization optimization of multi-source heterogeneous data for power grid planning and operation.
