Restrictions for equations

Hey! I have been modelling Load Shifting (LS) in a simple way which works so far: LS_level(t,c).. StorageLevel_LS(t,c)=e=StorageLevel_LS(t-1,c)+LS_in(t,c)-LS_out(t,c); (The storage level is equal to the storage level the time period before plus what is stored from the system minus what is given back...

Re: Simple Load Shifting Equation

Actually it seems like I made a mistake analyzing the results so the problem above is resolved but I figured out another problem with this equation which I have not been able to resolve... The equation LS_in(t,c)=e=LS_out(t+1,c)+LS_out(t+2,c) leads to the problem that the values LS_out can be counte...

Simple Load Shifting Equation

Hi, I have a GAMS model of an energy network and am trying to setup a simple equation to add load shifting. I want a maximum of 1000MW to be shifted and the shifting time is limited to two time steps (which in my model is the difference to energy storages). LS = Load Shifting, SL_LS = storage level ...

Modelling Load shedding

Hi there! I am quite new to Gams and am still frequently running into problems, so I was hoping that maybe one of you guys could give me some input on how to solve my problem. I have a model of an energy market with the different powerplants, the renewable energy feed in and the demand for energy fo...
