Does LDEs dispatch increase the standard capacity credit of energy storage capacity?

However, regardless of the test system and energy mix, the ideal LDES dispatch approach increases the standard capacity credit of total energy storage capacity (combined short-duration and LDES) (e.g., an increase between 8.8 % and 15.7 % on the standard capacity credit of the total energy storage capacity).

Can long-duration energy storage dispatch approaches reduce production costs?

Long-duration energy storage dispatch approaches are reviewed. Performance of energy storage dispatch approaches is assessed. A novel metric for energy storage capacity credit estimation is proposed. A better storage dispatch approach could reduce production costs by 4 %–14 %.

Does exogenous dispatch model represent optimal operation of energy storage technologies?

The exogenous dispatch model may not accurately represent the optimal operation of energy storage technologies due to necessary simplifications in dispatch model.
