hello
I'm student of electrical engeenearing.Ihave some questions about opf at
matpower.at"poewer system analysis" by Johnj.grainger
and WilliamD.Stevenson- i understood for computation lambda we have gencost
function (Quadratic function like C= aP^2 +bP+c)
and lambda=dc/dp , and for optimal power flow all the lambdas must be
equal.but at matpower when we run the opf ,for each bus
we earn one lambda.i want to know what function we use and how it compute.(for
example for PQ buses.)
another question , at help IDX_BUS it said :" bus(:, VMIN) = 0.95; % set the
min voltage magnitude to 0.95 at all buses"
but when you type it at matlab prompt it never influence our computation.please
help me about this .(have can i set the min voltage magnitude to 0.95 at all
buses)
Best regards
