该文基于模型预测控制理论, 提出一种考虑多时空尺度协调的风电集群有功分层预测控制方法。 该方法将风电集群在空间尺度上分为三层控制层,将超短期风电功率预测值在时间尺度上逐层细化,并对各层滚动优化环节进行了优化建模。 仿真分析中通过与常用有功分配方法对比, 结果表明文中所提方法在保证系统安全运行和满足集群计划的同时,能够提高风电消纳能力,合理利用风能资源和分配集群内风电功率。(Based on the model predictive control theory, this paper proposes a wind power cluster active layered predictive control method that considers multi-temporal scale coordination. The method divides the wind power cluster into three layers on the spatial scale, and predicts the ultra-short-term wind power prediction value on a time scale, and optimizes the rolling optimization of each layer. Compared with the commonly used active power allocation method in the simulation analysis, the results show that the proposed method can improve the wind power consumption capacity, rationally utilize the wind energy resources and allocate the wind power in the cluster while ensuring the safe operation of the system and meeting the cluster plan.)
针对使用传统分类器预测配变重过载会因为重过载样本率较低而带来的总正确率很高,重过载预测正确率却很低这一问题,将重抽样与随机森林理论引入分类模型中,构建重抽样-随机森林分类器对配变重过载进行预测。结果表明,新方法在预测配变日重过载类型、重过载开始与结束时间、重过载严重程度方面有较高的准确率。(For the problem of using the traditional classifier to predict the distribution of heavy overload, the total correct rate is high because of the low overload sample rate, and the accuracy of the heavy overload prediction is very low. The resampling and random forest theory are introduced into the classification model. In the construction, the re-sampling-random forest classifier is used to predict the heavy-duty overload. The results show that the new method has higher accuracy in predicting the type of daily variable overload, the start and end time of heavy overload, and the severity of heavy overload.)
