How to set a GLOBAL negative emission constraint - q-z17 - 28-09-2020
I try to use the UC_RHST to set the emission path of CO2. And I want to simulate negative emssion scenario. But GAMS reported error:"Row 'EQE_UCT('CO2AGG'.2050)' infeasible, all entries at implied bounds." I set "UC__RHST CO2AGG - - - - UP 0 9951541.927 9980232.24 9800000 7250000 6110000 2650000 -1000" According to a thread by wangh11, I set VAR_COMPRD for CO2 in every region,like region "CHON": "CHON COM_BNDPRD - CO2 - - ANNUAL NB 0 -1 -1 -1 -1 -1 -1 -1" "CHON COM_BNDPRD - CO2 - - ANNUAL LO 0 0.00 -5,000.00 -10,000.00 -15,000.00 -20,000.00 -25,000.00 -30,000.00" And LO bound for CO2AGG: "UC__RHST CO2AGG - - - - LO 0 -10000000 -10000000 -10000000 -10000000 -10000000 -10000000 -10000000" If I change the value in 2050 from "-1000" to "0", GAMS can give a solution but the emission in each region is "0", I can't gknow which region need to have negative emission. By the way, the parameter about COMAGG ： "UC_COMPRD CO2AGG LHS - CO2 ANNUAL - 0 1 1 1 1 1 1 1 1 1" "C CO2AGG CO2AGG uconstraint UC_N,UCT,UCRULE"
