考虑温控型负荷特性影响的集群用户超短期负荷预测方法
Ultra-Short-Term Load Forecasting Method for Aggregated Users Considering the Impact of Temperature-Controlled Load Characteristics
摘要
Abstract
The load of aggregated users with a high proportion of temperature-controlled loads is prone to abrupt in characteristics due to factors such as temperature variations,leading to temporal distribution shifts in load characteristics across different historical periods.This results in poor performance of existing load forecasting modeling methods for aggregated users due to insufficient generalization capability.Drawing on the concept of transfer learning for extracting domain-invariant features in the spatial dimension,an ultra-short-term load forecasting method for aggregated users based on time-domain invariant feature modeling is proposed.Since the cycles of temporal distribution shifts in load data and the boundaries of these cycles are typically unknown,firstly,the temporal distribution shift is quantified,and the load is segmented into sequences with significant distribution differences to support the subsequent extraction of time-domain common features among samples.Then,a Transformer-based time-domain invariant feature extraction algorithm is proposed,which minimizes the temporal distribution differences among data samples with varying distributions to extract time-domain invariant features,thereby optimizing load forecasting modeling and improving prediction accuracy under scenarios of abrupt load characteristic changes.Finally,the superiority of the proposed method is validated using real residential load data.关键词
