Modeling and Optimizing Pumped Storage in a Multi-stage Large Scale Electricity Market under Portfolio Evolution [HydroWIRES]

PSH plants have been traditionally designed and used for large scale, daily energy arbitrage, but technological developments and changes to grid needs are making flexible operation more prevalent. Market participation models for PSH have not kept up with these changes, which means that the range of energy and ancillary services that PSH plants can provide are not being optimally allocated. The proposed work aims to develop a prototype enhanced PSH model for incorporation into MISO’s multi-stage market clearing process with proper consideration of the unique characteristics of PSH.
