The hybrid LLM-assisted trust and risk assessment module fuses multi-source evidence (physical residuals, communication anomalies, and market irregularities) to infer trust scores and risk levels
Small-disturbance stability analysis and control-parameter optimization of grid-connected virtual synchronous generator
Using experimental data, the proposed methodology for disturbance analysis was tested on the model of the PrInCE experimental microgrid at the Polytechnic University of Bari.
This paper presents detection and classification of islanding and non-islanding disturbances in a PV based microgrid scenario. To design effective pat
Resilience is increasingly important in microgrid design as extreme weather and grid disturbances become more frequent, yet there is no widely accepted, operationally interpretable
These disturbances arise primarily from the integration of Renewable Energy Sources and the variability of loads, leading to active power fluctuations at the interconnection point between the
To enhance the safety of microgrid switching and the identification of misoperations, we propose Time-Synchronized Misoperation Recognition (TS-MR), a method tailored to switching
Section 2 starts with a brief review of islanded microgrid with multiple distributed power sources, and then the proposed method is described. Frequency stability control strategy of island
Microgrids (MGs) are installed with renewable energy sources (RES) to meet the dynamic load demands. The frequency control of MG operating in an islanded mode is more difficult
However, the random and intermittent nature of renewable energy sources has triggered a series of PQD problems, resulting in transformer overheating, decreased product quality, reduced
Abstract In this paper, the voltage and frequency regulation of microgrid with unknown disturbances and non-linear dynamics was studied. The disturbance observer was designed and the
