The energy transition is driving major changes in distribution grids: integration of distributed energy resources, electrification of transport and heating, and winter peak management. Building energy flexibility emerges as a promising solution, but exploiting it requires new management mechanisms able to coordinate a very large number of actors without compromising grid reliability or economic efficiency.
Led by LIREI in collaboration with Hydro-Québec's LTE/IREQ and Polytechnique Montréal, this program develops the transactive approach along three axes: 1) local energy service platforms that unlock customer flexibility and motivate participation (service portfolios, customer behaviour models, decision-support tools, electrothermal models of Quebec buildings); 2) hierarchical organization of the distribution grid for management purposes (topologies, aggregation, distributed computing); 3) co-optimization of energy and ancillary service markets and improved resilience, including coordinated post-outage recovery.
