Dispatch rules for energy storage

Towards robust and scalable dispatch modeling of long-duration energy

The operational synergies between solar PV and diurnal storage, with <6 h duration [15], are clear given the predictable daily on-off cycle of solar PV; storage charges during the day when the sun is shining and generates during the evening or morning load ramps when solar PV is not available [25].However, questions remain regarding optimal dispatch strategies for LDES.
