The key transmission section is a reflection of power system weaknesses and is the focus of monitoring by grid operators. To quickly and efficiently obtain the key transmission section of the grid, this paper proposes a quick-searching method for the identification of the key transmission section. First, the existing geographic partition of the grid is optimized by the end node shrinkage and regio...Show More
The growing integration of power electronic devices in power systems has brought attention to frequency stability issues due to low inertia as well as inadequate frequency regulation. In this regard, the paper defines frequency stability and introduces the frequency response process. It then outlines the current research progress in frequency response analysis methods from three perspectives: math...Show More
This study provides an overview of the field of power grid safety analysis and simulation technology, focusing on the load model and parameters of the Central China Power Grid. With the help of big data analysis, the study analyzes the patterns of load changes with seasons, regions, and other factors, and conducts precise load modeling and parameter optimization analysis. This study introduces the...Show More
Reasonable configuration of reactive power compensation devices can achieve a better effect of suppressing phase-change failure at the same time of relative economy, which is conducive to guaranteeing the safe and stable operation of the multi-dc-fed receiving end power grid. A reactive power compensation optimisation method is proposed to suppress the phase change failure of the LCC-HVDC DC trans...Show More
This paper proposes a new load model for inverter-interfaced distributed generator with grid-forming control. The model is described by piecewise functions and easily integrates with synthesis load model. Various disturbances and grid impedances are considered to establish the generic range of model parameters. The model's accuracy was validated in various scenarios.Show More
Accurate electricity forecasting is very significant to power system. Modern smart grid has huge data and complex structure, and the nonlinear relationship between influencing factors and electricity demand is complex, random and changeable. Only by making full use of large amounts of data, accurate, stable and reliable medium and long-term electricity prediction can be made. Based on the traditio...Show More
