摘　　要：针对不同受限情况下风电场出力的概率性序列具有极大相似性的特点,文中对序列运算理论进行了进一步扩展。首先提出了一种新的序列运算——分离运算,分析了其相应的性质;提出了概率变化序列的概念及其与分离运算的关系,分析了概率变化序列的性质及物理意义;以概率变化序列在风电出力分析中的应用为例,详细讨论了概率变化序列的使用方法。仿真结果表明,使用概率变化序列进行计算,可以充分利用相似性序列的特点,以已有计算结果为基础,大幅降低计算量,提高计算速度。文中所得结果具有普适性,可应用于其他含相似性序列的寻优问题中。Given the great similarity of the probabilistic sequence for different limited wind power outputs, some advanced applications of sequence operation theory are proposed. A new sequence operation named separation operation is established and its operation rules are presented. Furthermore, the concept of probability change sequence is derived from the separation operation and its physical meaning is analyzed. The method of using probability change sequence is shown in detail, with the application of wind power output analysis as an example. The simulation results show that the probability change sequence can make full use of the characteristics of similar sequence, and improve the calculating speed greatly. The method is generic and can be used in other optimization problems with similar sequence.
