摘要

为解决因风电随机性带来的“弃风”问题,实现宽功率波动下的高效制氢,提出基于最小二乘支持向量机（LSSVM）的超短期组合预测模型,提高风电功率预测鲁棒性。通过变分模态分解（VMD）预处理将风电功率分解为不同带宽的子模态,以降低随机噪声及模态混叠的影响;引入蜻蜓算法（DA）优化LSSVM,建立超短期组合预测模型,以满足电解槽控制的时间分辨率及精度要求。以河北省某风电制氢示范项目为例,验证该算法对于高波动性数据具备更高的预测精度,为风电制氢系统的优化控制提供依据。

Abstract

A combined ultra-short-term wind power prediction strategy with high robustness based on least squares support vector machine (LSSVM) has been proposed, in order to solve the wind abandonment caused by wind power randomness and realize efficient hydrogen production under wide power fluctuation. Firstly, the original wind power data is decomposed into sub-modes with different bandwidth by variational modal decomposition (VMD), which reduces the influence of random noise and mode mixing significianly. Then dragonfly algorithm (DA) is introduced to optimize LSSVM kernel function and the combined ultra-short-term wind power prediction strategy which meets the time resolution and accuracy requirements of electrolytic cell control has been established finally. This model is validated by a wind power hydrogen production demonstration project output in Hebei Province. The superior prediction accuracy for high volatility wind power data is verified and the algorithm provides theoretical basis to improve the control of wind power hydrogen production system.
