Our paper on load restoration for islanded microgrids was just accepted by @IEEETCNS! Some key aspects:
Model #microgrid physics using DistFlow
Convex relaxations
Tailored constrained policy optimization

Real-time power system event detection is critical for system stability and resilience. We propose a novel stream learning classifier: the Hoeffding adaptive tree with instance selection for real-time event detection.

Check out our recent publication. We propose a unifying deep learning framework for short-term load forecasting. Our novel approach includes time-varying feature weighting, hierarchical temporal attention, and feature-reinforced error correction.

Thank you CCST @CCSTorg for having me in this important briefing (https://t.co/RE1FCvu0oG). It's a pleasure & honor to discuss the challenges and opportunities of microgrids. Thank you Chancellor Larive and Dean Wolf @BaskinEng_Dean for the great support! @ucsc @BaskinEng

[CCST @CCSTorg]

Communities across California are designing and installing #microgrids to improve their resilience during disasters and to meet their climate change and environmental justice goals.

But what are they, exactly?

🗓️ Join us Wed. 3/30 for a #CCSTbriefing:
