通过正交试验对果胶酶水解壳聚糖的工艺进行优化,并对降解过程中粘度、还原糖生成量、平均分子量等指标的动态变化进行研究。结果表明,果胶酶在50℃、pH值4.5、酶用量与壳聚糖质量之比为3、壳聚糖脱乙酰度为80%时对壳聚糖降解效果最佳,其中底物脱乙酰度对酶解效果影响极显著。在最适条件下,果胶酶对壳聚糖水解约1h,可控制产物平均分子量在2500左右。果胶酶降解壳聚糖的起始速度非常快,反应30min后粘度下降基本平稳;水解反应进行135min后,产物还原糖生成量逐渐趋于平稳。

针对传统短期预测模型在特殊天气下准确率低以及未考虑光伏运行环境后续变化的问题,提出一种基于多模式增量更新的短期光伏功率预测方法。在分析气象特征的基础上,根据历史情况预测广义天气类型,在日前根据预测天气类型制定相应的训练函数与数据增强方法,最后基于参数冻结技术对模型进行增量更新,提升了模型对特殊天气的刻画能力以及对后续环境的适应能力。在真实的光伏数据集上进行实验,结果证明该更新方法能有效提高预测准确性。
