Title:
COMPREHENSIVE IDENTIFICATION INDEX-BASED ENERGY STORAGE MULTI-SCENARIO APPLICATION SWITCHING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/108384
Kind Code:
A1
Abstract:
Disclosed is a comprehensive identification index-based energy storage multi-scenario application switching control method, comprising: analyzing power grid demand scenarios according to actual power grid data; dividing the demand scenarios into predictable planning demand scenarios and unpredictable planning demand scenarios; determining, by means of historical data and previous-day-data analysis, the time-period arrangement and planning on the day of the predictable planning demand scenarios; determining a calculation method for the actual active power output and reactive power output of energy storage in a time period of each predictable planning demand scenario; establishing an identification index to complete the identification of an unpredictable planning demand scenario; and establishing a switching index to determine whether to complete the switching of the unpredictable planning demand scenario. On the basis of a control policy of a plurality of application scenarios of a current energy storage access power grid and by combining actual power grid demand analysis, the present invention provides a multi-scenario application switching control method, and aims to achieve the goal of fully satisfying the demands of different power grids by means of energy storage access and by performing adaptive transformation that suits different power grids on same.
