Featured Work

solar panel energy station

Microgrid Implementation Modeling

GIS researchers created a model to simulate a microgrid’s performance in terms of distributed generation, storage, and load. The simulation uncovered ways to promote mutually beneficial collaboration between microgrid owners and utility companies.
