Title:
POWER GRID MIXING AND ROLLING SCHEDULING METHOD THAT CONSIDERS CLOGGING AND ENERGY-STORING TIME-OF-USE PRICE
Document Type and Number:
WIPO Patent Application WO/2020/143104
Kind Code:
A1
Abstract:
Disclosed by the present invention is a power grid mixing and rolling scheduling method that considers clogging and energy-storing time-of-use price, wherein 24 h in a day are divided into three periods, i.e., a 24-h period, a 1-h period, and a 10-min period, and the method specifically comprises the following steps: S1. obtaining a computing model, real-time data, and a prediction result for contact line power within a predetermined time; S2. monitoring whether a power grid scheduling period reaches 24 h; S3. performing day-ahead scheduling; S4. monitoring whether the power grid scheduling period reaches the 1-h period; S5. performing hour-ahead scheduling; S6. monitoring whether the power grid scheduling period reaches within 10 min; S7. performing real-time scheduling; and S8. entering the next moment. After S8, the method shifts to step S2 and starts again. The present invention performs day-ahead, hour-ahead, and real-time scheduling, respectively, and prediction accuracy is continuously improved following the continuously shortened time scale; during real-time scheduling, sampling is continuously performed for feedback and correction so as to ensure that a contact line is within a section safe state to ensure safe operation of the power grid.
