Title:
ISLAND POWER GRID ENERGY STORAGE SYSTEM HIERARCHICAL CONTROL METHOD FOR AMELIORATING NEW ENERGY POWER GENERATION FLUCTUATION
Document Type and Number:
WIPO Patent Application WO/2021/114849
Kind Code:
A1
Abstract:
An island power grid energy storage system hierarchical control method for ameliorating new energy power generation fluctuation. The method comprises: implementing a rolling scheduling method on the basis of a model predictive control thought (11); comprehensively considering the response capability of an energy storage system to whole-network economic scheduling instructions and lifetime loss of an energy storage lithium battery, so as to construct an energy storage system intra-day control model target function with the optimal economy (12); and constructing an energy storage system real-time control model on the basis that the intra-day control model target function is satisfied and solving the model, and determining charging and discharging plans for a lithium battery energy storage system and a super-capacitor energy storage system (13). A hierarchical dynamic control method, based on model predictive control, for an energy storage system is provided. The method comprises an energy storage system intra-day scheduling method in response to whole-network economic scheduling and an energy storage system real-time control method for stabilizing new energy fluctuation, so as to obtain an accurate energy storage control scheme.
