可以计算电力系统概率潮流

function pxi=calGCum(cgi, ngi, pgi)

% calculate cumulants of each generator
%cgi - perunit
%ngi- No. of generator
%pgi-availability

pxi=zeros(1,6);
pxi(1,1)=ngi*cgi*pgi;
pxi(1,2)=ngi*(cgi^2.0)*pgi*(1-pgi);
pxi(1,3)=ngi*(cgi^3.0)*pgi*(1-pgi)*(1-2*pgi);
pxi(1,4)=ngi*(cgi^4.0)*(pgi*(1-pgi)-6*(pgi^2)*(1-pgi)^2.0);
pxi(1,5)=ngi*(cgi^5.0)*(pgi-15*pgi^2+50*pgi^3-60*pgi^4+24*pgi^5);
pxi(1,6)=ngi*(cgi^6.0)*(pgi-31*pgi^2+180*pgi^3-390*pgi^4+360*pgi^5-120*pgi^6);
