摘要

为提高光伏功率预测的准确性和稳定性

提出一种基于双层分解和改进多目标浣熊优化算法（AMOCOA）的BiLSTM超短期光伏功率预测模型。其中

双层分解将改进自适应白噪声的完全集合经验模态分解（ICCEMDAN）与变分模态分解（VMD）结合

可充分挖掘高频信号中的信息。改进多目标浣熊优化算法（AMOCOA）通过引入自适应区域搜索策略与多项式变异算子提升了算法收敛性与多样性。首先

利用ICEEMDAN将历史光伏功率序列分解为多个分量

其次将高频分量利用变分模态进一步分解

得到周期性分量。然后通过AMOCOA对BiLSTM参数进行优化并建立各子序列最优AMOCOA-BiLSTM模型。最后对子序列进行重构得到最终预测结果。通过实际数据对模型进行验证

结果表明

阴天天气下相比BiLSTM

所提模型的均方根误差下降了51.56%

平均绝对误差下降了68.75%

稳定指标下降了50.74%

表现出更好的预测准确性与稳定性。

Abstract

To improve the accuracy and stability of ultra-short-term photovoltaic （PV） power prediction

the BiLSTM model based on dual-layer decomposition and an improved multi-objective coati optimization algorithm （AMOCOA） is proposed. The dual-layer decomposition combines improved complete ensemble empirical mode decomposition with adaptive noise （ICEEMDAN） and variational mode decomposition （VMD） to fully extract information from high-frequency signals. AMOCOA enhances algorithm convergence and diversity by introducing an adaptive region search strategy and polynomial mutation operator. First

ICEEMDAN is used to decompose the historical PV power series into multiple components

and the high-frequency components are further decomposed using VMD to extract periodic components. Then

AMOCOA is applied to optimize the BiLSTM parameters

building the optimal AMOCOA-BiLSTM model for each subseries. Finally

the subseries are reconstructed to obtain the final prediction results. The experimental results show that

under cloudy weather scenarios

compared to the BiLSTM

the root-mean-square error of the proposed model decreased by 51.56%

the average absolute error decreased by 68.75%

and the stability index decreased by 50.74%

showing better prediction accuracy and stability.
