中文摘要:

      针对目前园区综合能源系统管理中分布式本地可再生能源利用率低、用户侧购电成本高、源-储-荷协调不充分等现实问题，提出了数据驱动的实时调度决策方法和模型。该混合模型首先基于大量用能数据，应用K-means 算法对其特性指标与时间序列特征进行聚类分析，得出具有代表性的用能模式。然后引入参数化模糊推理系统与启发式优化算法，依据代表样本对模糊逻辑推理规则进行自趋优设计，从而得出实现园区综合能源系统经济化调度的实时控制模型。再通过实际数据集仿真计算验证了所提出方法和模型的有效性。

英文摘要:

      Aiming at the practical problems of low self -sufficient renewable energy utilization, high power purchase cost and in-adequate source -storage -charge coordination in the current energy management of active integrated energy systems, a data-driven real-time dispatching decision model is proposed. The hybrid model is firstly based on a large amount of energy consumption data for its characteristic indicators and time series characteristics, and the K -means algorithm is used for cluster analysis to obtain a representative typical energy consumption pattern. Then the parametric fuzzy inference system combined with the heuristic optimization algorithm is introduced, and the fuzzy logic inference rules are self-optimized based on the representative samples to obtain a real-time control model for the economical scheduling of energy - using systems.In the simulation calculation through the actual data set, the validity and feasibility of the model are verified.
