摘要： 针对新型电力系统实时运行期间,各个新能源机组的一次调频能力难以定量评估问题,源于数据驱动理论,提出一种基于卷积神经网络(convolutional neural networks, CNN)和层次分析法的新能源机组调频能力综合评估方法。以新能源机组有功出力、调频持续时间以及机组容量为指标,建立评估指标体系;采用卷积神经网络技术合理预测不同指标的数值,并通过层次分析法确定各指标间的相对权重。在PSCAD/EMTDC仿真软件中搭建包含风电场和光伏电站的IEEE 3机9节点模型进行仿真验证,算例结果表明所提出指标可以在数值上定量反映出各个新能源机组的调频能力,也验证了文中所提评估方法的有效性。
