The removal of the DC line may lead to power flow transfer, which leads to the wrong operation of the AC line distance III protection. To solve this problem, a modified distance backup protection that integrates DC control information is proposed. First, analyze the characteristics of DC side control information and propose a power flow transfer identification scheme that integrates DC control information. Subsequently, the modified distance backup protection is constructed using the identification results of the power flow transfer. Finally, an AC/DC hybrid model was established to verify the feasibility and fault resistance capability of the proposed scheme. © 2022 IEEE.

Very-short-term wind power prediction is of great significance for the safe and stable operation of power system. As a well-known time series model, vector autoregressive (VAR) model is very suitable for very-short-term forecasting, and it can consider the temporal and spatial correlation among multiple wind farms to improve the forecasting accuracy. However, when there are a large number of wind farms, VAR model is prone to over-fitting. Slow calculation speed is also the problem of VAR model. This paper adds regularization terms in estimating coefficients to obtain a sparse coefficient matrix, which helps to avoid over-fitting. Online VAR model is used to improve the calculation speed, and a specific improved online VAR method is proposed for forecasting wind power output from new-built wind farms. This method is tested in a specific case, and the prediction accuracy and calculation speed are better than the traditional VAR model. In addition, the improved online VAR method can accurately predict wind power output of new-built wind farms with little historical data. © 2023, Beijing Paike Culture Commu. Co., Ltd.

Due to its different characteristics from traditional synchronous generator, grid-forming converter (GFM-converter) affects the transient characteristics of the system when it is linked to the power grid. The mathematical model of the GFM-converter is built to describe its dynamic characteristics. Then, the transient process of the GFM-converter is analyzed qualitatively with the power-angle curve. The phase diagram method is used to study quantitatively and verify the validity of the above qualitative analysis. Finally, the influence of virtual inertia JGFM on the transient response is analyzed. In the case that equilibrium point exists after fault, decreasing virtual inertia improves the transient stability of the GFM-converter by increasing the damping ratio. When the equilibrium point does not exist after fault, the increase of JGFM reduces the virtual power angle at the time of fault clearing, and the power imbalance degree of the GFM-converter is reduced, thus its transient stability performance is improved. © 2022 IEEE.

Flexible interconnection of low-voltage distribution station area with power electronic device can realize dynamic capacity increase and coordination. When three-phase four-leg converter is used as a flexible interconnection device, there is no need to the isolation transformer, which can reduce the volume and cost of the system, but it will generate circulating current on the ground line. According to the main circuit topology of the system, the average circuit model of ground circulating current is established, and the influencing factors of ground circulating current are deduced. The low-frequency circulating current suppression strategy based on the average duty cycle control of the fourth leg and the high-frequency circulating current suppression method based on the DC side common mode inductor are proposed respectively for the low frequency and high frequency components of the ground circulating current. Finally, the simulation results show the effectiveness of the proposed average circuit model and the suppression method.

Safety is an important factor restricting the cascade utilization of lithium-ion batteries (LIBs). In this paper, the safety characteristics of fresh and retired lithium iron phosphate batteries are investigated by means of a heating-triggered thermal runaway (TR). The results show that under the heating condition of 200 W, the internal short circuit (ISC) can directly cause the TR of a new battery and lead to an explosion with an overpressure of 98.9 kPa. However, there is still a buffer time of 13.1-22.3 min between the ISC and TR for the retired battery with states of health (SOHs) of 80% - 60%, and the retired battery cannot explode. The large-scale ISC onset time, TR onset time, and TR onset temperature of the 70% SOH battery are 27.4 min, 40.5 min, and 179.9 °C, respectively, which are the smallest among retired batteries, indicating that the 70% SOH battery may be more likely to trigger TR. The findings can provide guidance for the safe application of retired batteries. © Published under licence by IOP Publishing Ltd.

Rapid and accurate static voltage stability assessment is crucial for the safe operation of large-scale interconnected power grids. Existing methods have failed to effectively filter key input variables in massive measurement data, limiting assessment accuracy. This study proposes an assessment method based on causal decomposition and reverse feature-enhanced temporal convolution networks. Initially, using bottom-layer measurement data as input, key variables are selected through causal decomposition, reducing the original feature set and enhancing computational efficiency. Subsequently, a reverse feature-enhanced temporal convolution model is constructed to fully mine data characteristics and achieve high precision assessment. Validation in an improved four-machine two-area simulation system demonstrates that this method significantly enhances estimation accuracy and algorithm performance while reducing the dimensionality of original variables.

The dynamic equivalent of large power grid needs to calculate the dynamic aggregation of equivalent generator parameters for a given synchronous units group. In this paper, the weighted aggregation method commonly used in engineering is reviewed, and the deficiency of capacity weighting method is pointed out, then a direct parameters calculation method for dynamic equivalent generator based on EEAC and the unit-grid phasor diagram is proposed. Its key techniques are to using the complementary-cluster center-of-inertia relative motion transformation (CCCOI-RM) provided by the EEAC method, the initial value of the power angle for corresponding equivalent generator of the coherent generators group at the fault moment is calculated, and the impedance parameters of the equivalent generator are solved step by step by different forms of unit-grid phasor equations according to the feature that the power angle cannot be changed abruptly before and after the fault moment. Compared with the weighted aggregation calculation method, the proposed method is simpler and has a clearer physical concept. Simulation results based on the real power grids verify the effectiveness of the proposed method.

Stability control system (SCS) plays a very important role in the operation of power systems, so it is correspondingly essential to ensure the reliability of the SCS during its experimental and verification process. However, there are numerous problems in the management of the paper form based experiment mode of SCS today, such as long circulation cycle caused by low work efficiency, insecure and diseconomy on storage. More importantly, it is difficult to query and review historical records quickly, and it may even lead to the loss of records for various reasons. In this paper, taking advantage of blockchain technology, all the information of each experimental stage of SCS, including the approval information, experimental environment information, experimental equipment information of each manufacturer, experimental test reports and conclusions, are packaged and distributed managed. And then, a blockchain based experimental management system framework with the unified data form and module interface is proposed, in which the whole process of process record can be traced and cannot be tampered with. The experimental management system can be applied in the whole process of the SCS, including the experiment scheme making, experiment environment constructing, experiment processing, result evaluating, and results storage, etc. The blockchain based mechanism and system framework is expect to take many advantage to experiment management of SCS. © 2021, Springer Nature Singapore Pte Ltd.

Magnetic flux leakage, as a basic physical parameter in power transformer, can be utilized to characterize the status of the winding. And the DC biasing, as a common abnormal operation condition, is caused by solar storms, DC power transmission and some railway power transmission. It can induce the current bias and the core saturation, further changing the distribution of the magnetic flux leakage. Therefore, it is significant and valuable to analyze the effect of DC biasing on spatial magnetic leakage flux. In the paper, we design a transformer finite element model with its physical fieldcircuit simulation module. The model with some detailed winding structure can obtain the accurate magnetic field signal. Then the effect of different degrees DC biasing on the magnetic leakage flux is analyzed in the inner key positions. And the 10kV shrunken experimental transformer imitating the 110 k V transformer is selected as the research object. Depending on the experimental platform, we obtain the actual magnetic field signals and explore the incidence relation between the magnetic leakage flux and the DC biasing. © 2022 IEEE.

With a growing share of renewable energy being incorporated into microgrids through power electronic converters, isolated microgrids are at higher risk of losing transient stability when exposed to significant disturbances, primarily due to the reduced inertia and increased nonlinearity inherent in power converters. This paper introduces a novel control strategy aimed at enhancing transient stability for the grid-forming converter within the islanded AC microgrid, utilizing model prediction techniques. By adjusting the output voltage of the grid-forming converter with the additional term produced by model prediction, the balance between the system's equivalent input and output torques can be accelerated. The proposed strategy's effectiveness and superiority are validated through simulation using MATLAB/Simulink. © 2024 IEEE.
