AI Technical Summary
Existing technologies lack a systematic methodology for static security analysis of isolated microgrids, making it difficult to meet real-time and computational efficiency requirements. Furthermore, data-driven methods are limited in application within power systems and cannot effectively utilize historical data to enhance analytical intelligence.
We employ a Physical Information Neural Network (PINN) approach, combining traditional power flow calculation models and data-driven methods. By constructing a deep learning model and embedding a physical constraint loss function, we achieve efficient and adaptive safety assessment.
It achieves efficient, adaptive and strongly constrained safety assessment of isolated microgrids, can dynamically modify the admittance matrix for N-1 verification, and combines computational efficiency with physical interpretability, making it suitable for high volatility scenarios.
