摘　　要：为了使出力的波动程度能直接反映水电平抑风电的效果,从量变和形变的角度提出了基于量维和形维的波动量化评估方法.以随机和实测过程为测验对象,并加以滑动平均、叠加平均、缩放等处理,与现行常用的波动量化评估方法——RBF方法进行了对比分析,多方位验证了所提方法的有效性和优越性.将其用于风电水电联合运行实例后,在多种的资源和装机条件下的计算结果均符合客观实际,结果表明了该方法在风电水电联合运行中量化评估出力波动程度的可行性.To directly reflect the effect of coordinate control of wind power and hydropower,by the fluctuation of output,a method based on quantitive dimension and contoured dimension（QC）was proposed.Compared with current common method,RBF（Richards-Baker Flashiness Index）,the validity and superiority of the proposed method was testified with random and actual measured processes and several disposals such as moving average,superposed average and zoom,etc.With application QC in case study of coordinate control of wind power and hydropower,the results accorded well with the objective rules.Results show the feasibility of apply QC to quantify the fluctuation of output of combined wind and hydropower.
