Decarbonizing our electricity and transportation sectors will require large deployments of wind, solar, and storage. Ranjit Deshmukh develops models for planning and operations of low carbon electricity grids and analyzes tradeoffs between economic, environmental, and social objectives for regions in the U.S., India, and Africa. These models optimize wind, solar, and other generation, demand, and storage resources for region-specific conditions including spatial and temporal variability of renewable resources.
