Extract this node simultaneously and constitute X in the result of calculation checking power flow algorithm_B=< x_B1,x_B2,...,x_Bn> and it is corresponding Marginal point set.Can be to sequence X according to index calculated below_ACarry out the assessment of dynamic mode distance:

$d(P_A,P_B)=\frac{2|l_1-l_2|}{l_1+l_2}+\frac{2|k_1-k_2|}{k_1+k_2}+\frac{1}{2}(\sqrt{{(x_{A1}-x_{B1})}^2+{(t_{A1}-t_{B1})}^2}+\sqrt{{(x_{A2}-x_{B2})}^2+{(t_{A2}-t_{B2})}^2})$

It is assumed that P_A1(x_A1,t_A1) and P_A2(x_A2,t_A2) it is respectively sequence X_AMarginal point, l₁For a P_A1And P_A2Length along path Degree, in like manner l₂For sequence X_BMidpoint P_B1And P_B2Line segment length.Embodying with l of line segment length₁As a example by,k₁And k₂It is then the slope of corresponding line segment, slope

Further, the calculating process of above-mentioned trend error extreme difference index is as follows: use maximum likelihood method estimation difference Average value mu and standard deviation sigma, thus realize the detection of abnormal voltage outlier, it is achieved voltage is calculated the bigger node of deviation Follow the trail of, wherein,

$\mathrm{\&mu;}=\stackrel{\&OverBar;}{x}=\frac{1}{n}\underset{i=1}{\overset{n}{\&Sigma;}}{x}_i$

$\mathrm{\&sigma;}=\sqrt{\frac{1}{n}\underset{i=1}{\overset{n}{\&Sigma;}}{(x_i-\stackrel{\&OverBar;}{x})}^2}$

In above-mentioned two formula, x_iFor voltage magnitude or the error amount of phase angle, n is the number of node.Meet in error In the case of normal distribution, μ ± 3, region σ comprises the data of 99.7%.Error amount is more than μ+3 σ, and the value less than μ-3 σ is screened For outlier, and add up the maximum i.e. trend error extreme difference index of outlier number and error.

It addition, the expression formula of above-mentioned average calculation times is:

$I_t=\frac{1}{N_m}\underset{i=1}{\overset{N_m}{\&Sigma;}}{t}_i$

In formula, N_mRepresent the total degree of moon Load flow calculation, t_iIn representing one month during calculating corresponding to i & lt Load flow calculation Between.
