RE: How to verify the feasibility of your solution without running Power flow?

I don't know what your algorithm does but I think you can do the same, determine optimal generation and load, using MATPOWER's optimal power flow (runopf). runopf supports all the constraints that you've listed. Shri From:

I am using an algorithm that changes the amount of demand and generation at each bus (Pd,Pg) to mitigate over load of lines and enhance the security. The output of my algorithm (Pd,Pg) must be checked to insure that they are feasible. So, it is obvious that by assigning this new calculated

Dear lavanya, you can set options like pf.nr.max_it=n maximum number of iterations for Newton’s method, pf.fd.max_it=n maximum number of iterations for fast-decoupled method pf.gs.max_it=n maximum number of iterations for Gauss-Seidel method Here, n is number of iterations. for your case n=1. The

Dear Shri Thanks for your answer. But I don't want to use runopf(). I want to write these constraint manually with Ybus and equations I've written. Is that possible? How should I start? Thank you. On Fri, Apr 10, 2015 at 1:24 AM, Abhyankar, Shrirang G. abhy...@mcs.anl.gov wrote: I don't know

Dear all, I want to run power flow for single iteration, but in MATPOWER software if i give command like runpf(casedata) for each iteration update the values of V,delta and P and finally gives me single result. If i want to run power flow for single iteration what can i do. Does anyone

Hello Lavanya, I guess you could achieve this by setting pf.nr.max_it to 1 (or pf.fd.max it or pf.gs.max it, depending on the powerflow method you use). See Table 4.2 in the Manual. -- Jose L. Marin Gridquant España SL Grupo AIA On Thu, Apr 9, 2015 at 9:28 AM, lavanya arubolu
