Energy storage is receiving increasing attention as a potential solution to integrate large amounts of renewable energy into the electrical power grid. However, a large-scale expansion of energy storage technologies in the power grid depends on several technical and economic factors. This talk starts with a brief overview of the status of grid-level energy storage and renewable energy in the United States. Then, we present findings from ongoing research at MIT and ANL on the potential role of batteries in future electricity markets, focusing on: 1) improved representation of batteries in power system optimization models, 2) computationally efficient algorithms for energy storage dispatch, 3) optimality conditions and cost recovery in electricity markets with energy storage and variable renewable energy, and 4) the potential role of energy storage in decarbonizing the electric power system.
