Smart protection system for identification and localisation of faults in multi-terminal DC microgrid
IET Smart Grid, 2020 DC microgrid provides the horizontal infrastructures to integrate distributed generation (DG) and loads. Unlike traditional AC systems, DC systems cannot survive or sustain high magnitude fault currents. It makes locating faults very difficult.

PhysicsâInformed Neural Networks for Battery Degradation Prediction Under Random Walk Operations
Quality and Reliability Engineering International, Volume 42, Issue 5, Page 1923-1940, July 2026.ABSTRACT This study addresses the challenge of predicting the state of health (SoH) and capacity degradation in Battery Energy Storage Systems (BESS) under highly variable conditions induced by frequent control adjustments. In environments where random walk behavior prevails due to stochastic control commands, conventional estimation methods often ...

Resilient Cooperative Control of DC Microgrids
IEEE Transactions on Smart Grid, 2019 Existing cooperative control of DC microgrids rely on a communication network that makes them vulnerable to cyber attacks. A trust-based cooperative controller is proposed that can mitigate adverse effects of attacks on communication links and controller hijacking. It only requires local and neighbor information to detect and mitigate an attack.

Decentralized DC Power Exchange System for DC Microgrids
EnergiesA decentralized DC power exchange method is proposed to enable direct bidirectional power transfer among geographically distributed DC microgrids. Each microgrid is connected to a shared power exchange grid via a bidirectional DC/DC converter, al-lowing flexible participation regardless of location.
