GAMS World Forum

can anyone help me with this issue? I know the problme is within this equation: WINDY (time)$(ord(time) GT 5) .. wind(time) =e= pdata(time,"R")$(pdata(time,"R") le twodandc(time)) + twodandc(time)$(pdata(time,"R") gt twodandc(time)); I am HAVE to use MIP and I believe t...

Hello my friends, I have an UC problem to solve using GAMS, however I got stuck on how I can write the equations constraints for the min run/down time, I will post here my code: sets time periods of time for generation /1*10/ gen generators /1*5/ table gendata(gen,*) generator parameters * fixed var...

Hello guys, here is my code for a uc problem: sets time periods of time for generation /1*16/ gen generators /1*5/ Alias (time,al_time); table gendata(gen,*) generator parameters * fixed variable start up * cost cost cost pmin pmax A B C D E F 1 50 110 40 9 220 25 7 5 2 80 240 55 5 500 20 6 4 3 70 1...

thanks!!
You were right, the code was the same. and both were wrong, I got the correct answer yesterday!
But thanks for the reply

I have this question here to analyse with gams: Several wind farms of total capacity 350 MW are now installed in the system. An additional operational constraint is introduced whereby the maximum contribution from wind generation at any given time is 30% of total demand. Wind generation has priority...
