针对海岛微电网负荷的强非线性、非平稳性及多源耦合特性,提出一种基于评价因子重构的鲁棒经验模态分解(REMD)结合细节增强卷积网络(DECN)与双向门控循环单元(BiGRU)的负荷预测方法。通过REMD与评价因子重构,实现多尺度特征解耦;构建DECN-BiGRU混合架构,融合局部差异与全局依赖特征;引入多任务学习优化分量耦合关系。试验表明,模型较传统方法的平均绝对百分比误差降低 68.78%,较深度学习模型的平均绝对误差降低 68.97%,验证了多模态特征融合与双向建模的有效性。研究结果为海岛微电网的电力调度与储能配置提供了参考。
Aiming at the strong nonlinearity, non-stationarity, and multi-source coupling characteristics of island microgrid loads, a load prediction method was proposed, integrating robust empirical mode decomposition (REMD) based on evaluation factor reconstruction with detail-enhanced convolutional network (DECN) and bidirectional gated recurrent unit (BiGRU). Multi-scale feature decoupling was achieved through REMD and evaluation factor reconstruction. A DECN-BiGRU hybrid architecture was constructed to fuse local differences and global dependency features, and multi-task learning was introduced to optimize the coupling relationships among components. Experiments showed that the model reduced the mean absolute percentage error by 68.78% compared with traditional methods and reduced the mean absolute error by 68.97% compared with deep learning models, thereby verifying the effectiveness of multi-modal feature fusion and bidirectional modeling. The research findings provide reference for power scheduling and energy storage configuration in island microgrids.
