Hi Jaromił Najman Najman,When I am trying to replace '<=' sign in the below constraint to '<', it shows me this error, why gurobi don't accept '<' sign? res = res_cat2idx['SP'][0]Spinningusage = {}...

Hi Jaromił Najman,Thank you for the response.I ran the optimisation model and when I saw the Battery power, I can see that it is continous variable rather than a discrete variable. Why so ?BatteryP...

Hi Jaromił Najman,Yes correct, I want to access BatteryPower[t].It can take any discrete value from [-3,-2,-1,0,1,2,3].How do I write it as variable?

Hi Jaromił Najman,This is how I define BatteryPower:What do you mean by 'is it only one variable?' # introduce variable BatteryPower for every timestep t BatteryPower = steel.addVars(time1, lb= -3,...

Hi Jaromił Najman,Also I am not sure why I am getting this error: initial_SoC = 0.5 Regards,Margi

Hi Jaromił Najman,Alright, That means I will need to define batterypower like below: # introduce variable BatteryPower for every timestep tBatteryPower = steel.addVars(time1, lb= -3, ub = 3, name="...

Hi Jaromił Najman,Does that mean If I define SoC as a variable, I don't require to define BatteryPower as a variable?

Hi Jaromił Najman, Thats correct. I understand but then how it is possible to calculate BatteryPower necessary for the objective function?   Regards,Margi

Hi Jaromił Najman,Actually the variable is the BatteryPower and SoC is calculated from it.  SoC calculation: if t == 1: SoC = initial_SoC(at t=0) + (BatteryPower * ch_eff) / e_b_cap else:    ...

Hi Jaromił Najman,I am trying to reformulate the optimisation problem. Objective function: for res in res_list4:    for t in time1:         # add constr aux = EnergyResouce - E       steel.addCons...
