As the global energy structure undergoes transformation and the reform of the power market deepens, in the face of the continuous expansion of the power grid scale and the increasingly complex structure, the construction of the technical supervision and management system for the power grid becomes particularly crucial for ensuring the safety of the power grid. This paper first analyzes the current...Show More
Electronic transformers are often used in conju nction with gas-insulated switchgear in power systems in har sh conditions. The current flowing through the high-voltage conductors of electronic transformers causes the device to he at up, which affects the reliable operation of the device. In this paper, the multi-physical field coupling simulation model of the electronic transformer is established...Show More
The huge amount of measurement data provides the basis for the data-driven transient stability assessment (TSA) method. However, the unstable samples are usually much less than the stable samples in the TSA, this inherent attribute affects the performance of such methods. Therefore, this paper proposes a TSA method based on SVM-SMOTE and 1D-CNN. The support vector machine-synthetic minority oversa...Show More
In recent years, the world has been increasingly concerned about energy scarcity and environmental pollution. This has led to a greater emphasis on developing renewable energy sources. To address the challenges of renewable energy variability, an effective solution is to use energy storage systems. To establish a seamless connection between the energy storage system and the grid, the incorporation...Show More
As the renewable energy generation develops, its fluctuation and intermittency have to be considered. Configuration of energy storage system is a solution, which can balance the power produced and the power consumed. As the interface between energy storage system and the grid, bidirectional DC-DC converter is required. However, the conversion ratio of commonly-used nonisolated bidirectional conver...Show More
Due to the increasing use of power electronic converters in the grid, the grid requires higher quality of grid-connected currents from grid-connected inverters. The use of power filters on the grid side is the main method to improve power quality, however this increases the complexity of the system architecture. In addition, increasing the switching frequency can also reduce the size of the filter...Show More
A decision-making method for power system transient stability control was proposed considering the uncertainties of wind generation and load. Firstly, the transient stability margin is defined taking the salient pole synchronous generator model into consideration. The Gaussian mixture model (GMM) was used to describe the uncertainties of wind power and load. The probabilistic transient stability o...Show More
This article proposes a micro magnetic field sensor based on the coupling of magnetostriction-piezoelectric effect. The principle is that under the action of a magnetic field, the magnetostrictive material undergoes deformation, causing stress on the piezoelectric cantilever beam and resulting in its deformation. Due to the piezoelectric effect, the cantilever beam generates an electrical potentia...Show More
