Focused on tackling the issue because the electricity theft detection model has low applicability and the recognition rate is greatly affected by subjective factors like manual extraction features, a power-stealing user recognition model based on feature engineering and integrated classifier is proposed. The model uses Tsfresh and Whale Optimization Algorithm (WOA) as the main feature extraction and selection tool. Then we use an integrated classifier to identify the abnormal users. Firstly, we collected the electricity consumption data of 600 different users for 583 consecutive days. Secondly, the rough feature extraction is performed by Tsfresh and the variance-based method. Thirdly, the Whale Optimization Algorithm is used to finely select the features, getting the most suitable feature parameters. Finally, the integrated classifier is used to classify abnormal users. After evaluating the performance of different classifiers ensemble, an integrated classifier is composed of a Decision Tree (DT), Support Vector Machine (SVM), and Random Forest (RF). Meanwhile, in terms of feature extraction, we compared the results of three single classifiers which consist of the integrated classifier, also compared with other feature selection and classification methods. The experimental results show that the average accuracy of this method is 96.11%, which is higher than other methods. © 2024 IEEE.

This paper analyzes the device voltage overshoot in the symmetrical hybrid five-level converter. Owing to the presence of stray inductance, the voltage that the power devices need to withstand during switching operations may exceed their rated values. To address this issue, a device voltage overshoot suppression method suitable for the topology is proposed in this paper. This method suppresses SiC MOSFET voltage overshoot through adjustment of switching speed and the utilization of snubber capacitance, and it employs the design of RC and dual-RCD snubber circuits to suppress Si IGBT voltage overshoot. Simulation and experimental results certificate the effectiveness of the proposed method in suppressing device voltage overshoot. © 2024 IEEE.

Fully DC wind turbine generator system is a promising substitute for conventional AC one. In the system, the LLC step-up converter plays a key role. Mode analysis and time-domain expressions can provide more accurate estimation of the resonant performance than the conventional First Harmonic Analysis method. The circuit works at different modes as the load rate varies. This paper categorizes these resonant behaviors into four modes, with time-domain expressions of each mode obtained. The variation regular of these modes is given and is applied in the program to realize recognizing the working mode automatically. The simulation and experiment have verified the effectiveness of the proposed method. © 2023 IEEE.

With the proposal of carbon peaking and carbon neutrality goals, the proportion of renewable energy generation continues to increase and the number of new photovoltaic power stations is growing rapidly. Accurate photovoltaic power prediction is of great significance for the safe, stable and operation of power system. In order to solve the problem of insufficient historical data of newly constructed PV power plants, this paper proposes a short-term PV power prediction model based on Long Short Term Memory and transfer learning. The model uses meteorological data, numerical weather forecast data and PV power as features. According to the transfer learning theory, the Long Short Term Memory model is pre-trained using the historical data of other previously-built PV power plants, and then a small amount of local operation data is used to fine-adjust the model. Case study based on Hebei open source photovoltaic and meteorological data set proves that the proposed transfer learning model can effectively improve the short-term PV power prediction accuracy, and the MAPE can be improved by up to 15%. © 2023 IEEE.

Conventional nanosecond clock synchronization protocols are generally target-type or content-type, the synchronization rate is low, which leads to the increasing of the mean value difference of synchronization, so we propose to study the design of nanosecond clock synchronization method for real-time transient simulation. Combined with the actual clock synchronization requirements, we first calculate the link congestion coefficient, adopt a multilevel approach to strengthen the synchronization rate, set up a multilevel clock synchronization protocol, based on which we determine the clock source quality coefficients and construct a nanosecond clock synchronization model for real-time transient simulation, and use redundancy processing to achieve clock synchronization. The test results show that compared with the high-efficiency phase-color clock synchronization method and the cross-clock synchronization method, the mean synchronization difference of the designed transient simulation nanosecond clock synchronization method is controlled to be less than 0.5, which indicates that the designed clock synchronization method is more efficient, stable, and targeted, and the synchronization effect is significantly improved. © 2024 IEEE.

In the context of the digital transformation of power systems, various new sensors are capable of acquiring massive real-time data from the power grid, providing an opportunity for the development of digital twins in power systems. This paper proposes a transient stability assessment digital twin framework based on knowledge distillation. Addressing the challenges of high computational resource consumption and model deployment difficulties associated with existing high-precision complex models in transient stability assessment, the knowledge distillation method is introduced for model lightweighting. Simultaneously, the proposed continuous learning online updating strategy enables adaptive online updates for complex operating conditions and structures, enhancing the learning capability for online additions of diverse samples. Using Transformer as the transient stability assessment model, the effectiveness of the proposed approach was validated on the IEEE 39-bus system. © 2024 IEEE.

LCC converter has the characteristics of both series resonance and parallel resonance, which is often used as the front stage of high voltage DC power supply. A three-stage boosting circuit using LCC converter, high-frequency transformer and voltage multiplier circuit is applied to a high-voltage source. In order to realize the design of core resonant cavity parameters, firstly, the working process of LCC converter in continuous current mode (CCM) is solved by using the operation mode analysis method. On this basis, considering the integrated design of stray parameters such as stray capacitance and leakage inductance of high-frequency transformer, the resonant cavity design flow of LCC converter is given. Finally, an experimental platform is built to test the LCC converter and the whole boosting circuit, and the voltage transmission ratio of 20V/10kV is verified. © 2023 IEEE.

power transformer failures often result from elevated hot spot temperatures, which disrupt the regular operation of power systems. To precisely determine the hot spot temperature of transformer windings, this paper employs a 110kV oil-immersed power transformer as a case to develop a three-dimensional electromagnetic-temperature-fluid multi-physics coupling simulation model for the transformer. The core and winding loss density distribution is obtained through magnetic field calculations. On this basis, the loss density serves as the heat source, and temperature and flow field simulations for the transformer are conducted using thermal-fluid coupling. In addressing the issue of temperature discontinuity at the interface of fluid and solid coupled heat transfer, an adaptive grid refinement method is adopted to enhance grid resolution at the interface while employing a coarser grid in flatter regions, thus enhancing the precision of numerical simulations. Finally, the simulation results are compared with hot spot temperature calculations obtained through empirical formulas, confirming the method's feasibility. © 2023 IEEE.

The growing adoption of natural gas in power systems has led to a heightened focus on the resilience of coupled electric-gas system when confronted with large-scale faults during extreme disturbances. In this study, we examine the sequential recovery procedure of a coupled electric-gas system after experiencing severe faults. We propose an optimization method to enhance the resilience of the coupled electric-gas system. This approach integrates remote switching and isolated island to attain swift fault isolation and restoration. The primary goal is to enhance the system's resilience to extreme incidents and expedite its recovery. Firstly, a model for a coupled electric-gas system is developed to represent the power system, natural gas system, and energy conversion center. Subsequently, detailed models are created for the load shedding phase, fault isolation phase, and service recovery phase that occur in the coupled electric-gas system following extreme faults. These models encompass the topological constraints, power constraints. To illustrate the strategy for improving the resilience of the coupled electric-gas system, we employ practical examples involving the IEEE 33-node power system and a 7-node natural gas system. The simulation results indicate that this strategy effectively improves system resilience. © 2023 IEEE.
