SCUC in matpower

2018-11-14 Thread Aamir Nawaz
Dear Dr. Ray, I want to do SCUC using matpower. I already know that MOST have deterministic and stochastic UC feature. So my question is that can it do security constrained UC? if yes, then how can i get line flows data as MOST output does not give such information. I want to use line flows inform

Hello Doctor: I have a question whilst using MOST, I hope you can help me out clarify this. I am running a dcopf study using MOST. My system is the IEEE RTS 24 bus. I am including reserves for each generator, as well as costs; these input data is in the ex_xgd_res function. I am adding one continge

To clarify a little further on Ray's advice: An SVC can be approximated by a generator under voltage control that can sink QMIN or source QMAX MVArs, but this would be accurate for an SVC with a slope of infinity (i.e., constant voltage).  If you want

Hi, The AC power flow (runpf) is converging for your system, while the AC optimal power flow (runopf) does not. The reason being the line ratings (rateA, B, C) are less than the load they are supplying to. For instance, the load on bus 2 is 2.8 MW, but there is a single line 1-2 supplying pow

For HVDC lines, see section 7.6.3 in the User’s Manual . And an SVC can be modeled as a generator with PMIN and PMAX equal to 0. Ray > On Nov 14, 2018, at 5:43 AM, in...@gotalk.net.au wrote: > > Dear Ray > > Does MATPO
