A cloud-based system developed by Washington State University allows for local energy trading and sharing within neighborhoods, resulting in potential cost savings of up to 12% over a five-day test period. The system, tested in collaboration with a local utility network, highlights the importance of coordinated operation at the distribution level in the changing electricity industry landscape. Published in the journal IEEE Transactions on Industry Applications, the research paper presents a community-based transactive coordination mechanism for enabling grid-edge systems, with the ability to reduce energy costs by up to 12% in communities with solar and battery energy storage systems.
