sparfilt
优点:1.对于信噪比高的信号滤波效果好;
% 2.对于边沿的保护强过阈值滤波,不会产生阈值滤波情况下的过于平滑与Gibbs现象。
%缺点:1.由于对边沿信号没做任何处理,所以边沿可能会有脉冲噪声保留下来;
% 2.计算相关系数中,如果计算出来的小波系数点位置偏差大,则相关系数计算受影响;
% 3.需要迭代运算,迭代的噪声能量阈值选取很重要,这里以开始段无信号处估计噪声;
% 4.需要迭代运算,所以运算量比阈值法大;
% 5.受分解层次影响,在大尺度上小波系数点位置偏差更大,相关系数计算不准确。
%需要具体调整的地方:1.分解的尺度;()

概率潮流计算
说明: 为考查各种不确定性因素对系统运行的影响,需要大量地重复性潮流计算。结合概率理论形成的概率潮流计算能够充分考虑这些不确定性因素。由概率潮流计算可以得到节点电压、电流、支路潮流的均值、方差、概率密度函数等统计特性,从而更全面地反映系统运行状况。(In order to examine the impact of various uncertainties on system operation, a large number of repetitive power flow calculations are needed. The probabilistic power flow calculation based on probability theory can fully consider these uncertainties. Statistical characteristics of node voltage, current and branch power flow, such as mean, variance and probability density function, can be obtained from the calculation of probabilistic power flow, thus reflecting the operation status of the system more comprehensively.)
