Sustainability of building energy via digital intervention in distributed systems


Digital technologies are unlocking new data streams for renewable distributed energy resources (DERs) creating the potential to provide not only capacity or wholesale products, but also new flexibility and demand side response services. Due to the small scale of individual buildings, aggregation is needed whereby a digital system can mediate the availability, and rewards, for acting together in the energy market. Such opportunities are especially important in constrained areas of the distribution network. This work examines the considerations of such an integrated solution and presents results from a simulated network based on real DER data.
