Beg your pardon the missing snippet from the previous mail is as follows:
%% initial state
%V0= ones(size(bus, 1), 1);%% flat start
V0 = bus(:, VM) .* exp(sqrt(-1) * pi/180 * bus(:, VA))
vcb = ones(size(V0)); %% create mask of voltage-controlled
buses
Hello,
I am Sayandev Ghosh, presently teaching power system in an undergraduate
engineering college. I have done my M.Tech on Energy Science from Jadavpur
University. I have been using MATPOWER for load flow analysis of till 118
bus by Newton Raphson method. While doing that I am not able to
Dear all
I am facing problem in DCOPF. I need help. In my power grid model i
have fixed the capacity of transmission line in RATE A column by 110% of
initial power flow. Then increase the load by a factor (1.01) and run the
dcopf. But matpower showing infeasible model due to which
Hi Sayandev,
As you know, iterative methods need an initial guess. But this is the
user's *choice*: you can use a flat start as you mention, or any other
information you may have (for instance, from previously solved cases that
are similar to the one at hand---as it happens when solving N-1

Hi,
I have found a small bug in the CPF function. Suppose the base case power
flow converges but the very first corrector step fails. Then the following
happens
1. cpf loop sets *cont_steps = 0 *and terminates with break
2. callback function is called with *k=0 *and thus executes initialization
