Going on from previous tutorial , into following rows I'll define the modelling of ESS component I used:

*(A working model of EMS Online Simulator is available every day from 16.00 to 18.00 UTC)*

ESS Model:

- CAPABILITY and Signs:
- circular 1MVA (no overload)
- P+ = Discharge battery
- P- = charge battery
- Q+ = reactive power injection into the grid
- Q- = reactive power absorption from the grid

- BATTERY:
- Lithium base battery, nominal Energy=1,2 [MWh], CP rate=1;
- Vcell = 2.8 to 4.2 [Vdc]
- Thermal de-rating: not simulated
- Power limit de-rating in case of SOC>95% or SOC<5% (linear)
- Efficiency: load indipendent (defined into source code)
- SOH (State Of Health) : not simulated
- SOC (State Of Charge) calculation: interpolation (Catmull-Rom spline) based on following SOC-V diagram

- PCS:
- 2-state converter
- V (MV side) = 15 [kV] AC
- V (LV side) = 550 [V] AC
- V (DC side) = battery dipendent
- Estimated self-consumption: 2kW
- Regulating point : MV side
- Efficiency: load indipendent (defined into source code)
