Abstract: The electric power system is undergoing a rapid and deep decarbonization with the increasing penetration of renewable energy sources. The heightened penetration level of renewables in the form of distributed energy resources (DERs) underscore their growing significance as providers of grid services. Being small-scale and distributed in nature, these devices will need to be effectively aggregated before integrating in the wholesale electric market and providing grid services. Navigating the inherent stochasticity is one of the major challenges in designing effective aggregation strategies for DERs. In this talk, several major challenges of effective DER aggregation/integration will be discussed, along with some proposed methods to address them. In particular, we will present some decision-making models and algorithms for the characterization and improvement of the aggregate flexibility regions of aggregate DERs, as well as the development of their market participation strategies under uncertainty.
