Defense Algorithm Based on Reinforcement Learning and Digital Twin for Distribution Protection Devices Adversarial Samples

Engineering Reports, Volume 8, Issue 6, June 2026.
Power system protection devices are vulnerable to adversarial samples. We propose a digital twin and reinforcement learning framework. It trains a virtual model within safe operational boundaries, reducing the false operation rate to below 3.5%. The model's inference delay is under 10 ms, meeting real‐time protection requirements.

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

High Voltage, Volume 10, Issue 6, Page 1464-1473, December 2025.
ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐

Development of an Electromagnetic‐Thermal Circuit Model for Single‐Phase Three‐Limb Transformers

High Voltage, Volume 10, Issue 6, Page 1545-1557, December 2025.
ABSTRACT Analysing the heat states of transformers under DC bias requires careful consideration of their own structural and material characteristics. Although the 3D finite element method (FEM) is a reliable way of simulating all the details of transformers, it may be time‐consuming or have encountered convergence difficulties due to the complex ...
