摘要(Abstract)：

多能源电力系统将成为主要的能源供给方式。为解决各种异质能源发电模型差异性大、相容度不高的问题,明确多种能源耦合机理和基本规律,通过风电、光伏和水电的多源数据驱动,基于因子分析法建立了多种异质能源同质化表征模型,将异质能源输出功率统一表征为"功率水平分量+波动分量+差异性随机分量+预测误差分量"之和;以此为基础,采用近邻传播(affinity propagation,AP)算法对低维特征因子聚类分析,进而建立一种计及风–光–水耦合特性的多场景发电模型,并提出了用于评价多种异质能源耦合特性的耦合度指标。算例以西北地区电网实测数据为研究对象,结果表明所构建的同质化表征模型具有有效性及可行性;基于同质化模型生成的不同场景耦合差异性特征明显,可为多能源电力系统的规划运行提供基础。
