The U.S. Department of Energy’s Energy Efficiency and Renewable Energy (EERE) office support research for a range of distributed energy resource (DER) technologies, including distributed photovoltaics, smart buildings, wind, water, behind-the-meter-storage, electric vehicles, and more. This paper explores the impact of integrating multiple DER technologies simultaneously in order to comprehensively address DER integration challenges across the portfolio of EERE technologies. This project built on existing work to understand technical challenges, mapped out the key research questions, assessed relevant capabilities across the national laboratory network, identified key gaps, and produced a research roadmap to inform future research.
