RE: Question about LMP

Dear Carlos and Sarmad, Thank you very much for this explanation. I really agree with the derivation of the Lagrangian function. My doubt was for the printing information (LPM) after a DCOPF is carried out. When there’s congestion, the LMP are correct, but we need to include the shadow price

Re: voltage drop calculation in radial system

Thank you very much for your explainations and advices. So to understand how matpower operate i looked at "MATPOWER: Steady-State Operations, Planning, and Analysis Tools for Power Systems Research and Education" and the calcultion done in matlab but i'm stuck with something. In dSbus_dV.m

Re: Different results with MATPOWER and PSAT

I'll add my 2 cents. I don't know PSAT, but I can attest to the difficulty in reproducing exactly the same powerflow solution in two different software tools, in general. First you have to find out how many features are implemented and enabled/disabled in each tool; but more importantly, you have

You may also want to check out the MATPOWER Tech Note on "AC Power Flows, Generalized OPF Costs and their Derivatives using Complex Matrix Notation ” listed on the MATPOWER web page. Ray > On Nov 20, 2015, at 11:16 AM, ALI
