Abstract
Description
Technical Field
[0001] This invention relates to the field of energy storage system control technology, and specifically to a dynamic scheduling method for industrial and commercial energy storage based on machine learning prediction. Background Technology
[0002] With the upgrading of energy consumption in the industrial and commercial sectors and the advancement of dual-carbon goals, energy storage systems, as core equipment for optimizing energy allocation and improving energy efficiency, have attracted much attention for their dynamic control technology.
[0003] Currently, commercial and industrial energy storage systems face three major technical bottlenecks in dynamic control, severely restricting their economic efficiency and energy utilization efficiency: First, rigid and ineffective control strategies: Traditional EMS systems use preset peak-valley charging and discharging periods, failing to respond to dynamic load changes. For example, actual data from a manufacturing plant in Jiangsu shows that under a fixed-period charging and discharging strategy, the maximum demand exceedance rate of the energy storage system reaches 27%, with demand electricity costs only reduced by 9%–12% (far below the theoretical optimization space of 20%–25%), and the control cycle is over 2 minutes, unable to respond promptly to rapid load changes. Second, insufficient load forecasting accuracy: Existing forecasting models rely solely on macroscopic load curves and meteorological data, neglecting to consider equipment start-up and shutdown events, resulting in forecast errors as high as 15%–22%. Furthermore, they generally ignore the correlation between real-time solar intensity and photovoltaic output and load, leading to photovoltaic absorption prediction deviations >25%. Third, traditional LSTM models, with a time step of 15 minutes, cannot capture the 30ms-level instantaneous power changes during equipment start-up and shutdown, resulting in delayed prediction of load abrupt changes. Conflict between anti-backflow and capacity utilization: Traditional anti-backflow solutions mainly rely on direct curtailment of solar power or restriction of photovoltaic output, which cannot fully utilize photovoltaic capacity and result in significant revenue loss.
