Beschreibung
Zusammenfassung:	The invention provides a power grid energy storage double-layer optimization method and system considering flexibility and new energy consumption, which can fully mobilize the flexibility of the system to supply resources, adapt to the uncertainty demand of the system, and obtain an energy storage scheme which meets the requirements of operation and optimal configuration at the same time. The power grid energy storage double-layer optimization method considering flexibility and new energy consumption comprises the following steps: step 1, based on a flexibility theory, establishing a flexibility adjustment model of a thermal power generating unit, an energy storage device and an interruptible load, analyzing new energy consumption, and establishing a consumption model; step 2, according to the flexibility adjustment model and the new energy consumption model, establishing an index system considering flexibility and new energy consumption; step 3, objectively weighting each index in the index system in the ste
