Hi everyone, i am making optimization for energy management system of EV charging station. I established the mathematical model objective function (minimization of electricity cost) and constraints then i made a Python simulation. In the simulation results, i got the charging station load profile (power profile and energy profile) the energy charged in the car is discharged later on in the charging station and i got in the end 0 cars charged. Anyone can help with ideas on how i limit the energy discharged to be equal only to the initial amount of the car and not every EV charged it discharge later. Thank you.
What kind of storage energy system are you using in your project? Battery,capacitor...etc.
Ashraf Mohamed li-ion battery and i am using this equation to model it:
Energy(t) = Energy(t-1)+ Powercharge(t)*delta t - Powerdischarge(t)*delta t
Energy is equal to a half of capacity time square of its voltage
