Beschreibung
Zusammenfassung:	The invention discloses a multi-time scale power distribution method for a regional power grid containing an energy storage power station, which comprises that: Construct a regional power grid model consisting of renewable energy, variable load, slow response energy storage units and fast response energy storage units, wherein the model includes the constraints of state-of-charge, electric quantity, charge and discharge, energy balance and the like of the energy storage units in fast and slow stages; Based on the regional power grid-related constraints constructed establish the cost target of energy management in the regional power grid and obtain the regional power grid optimization control model; And based on the regional power grid optimization control model, use the Lyapunov optimization method and random approximation technology to process and simplify the regional power grid optimization control model.
