| The benefits of utilizing and integrating large-scale hydropower into grid operation are multi-faceted. Run-of-river (RoR) hydropower by itself has limited dispatchability, but RoR and energy storage hybrid resources have much more flexibility and controllability in their operations. At the system level, these hybrid resources will impact electricity market operations, and the full benefit will depend on how these resources are configured, controlled and represented in market models. The project team will develop a RoR and energy storage hybrid resource representation model to represent the new combination of resources in the day-ahead market. This model will be used for security-constrained unit commitment and for siting and sizing of energy storage paired with RoR in an independent system operator size system. The objective of this project is to assess the benefits of co-located and/or co-optimized hybrid RoR hydroelectric generators and energy storage resources from a system operator perspective. |
