Reference System

The reference system is built up by specifying the included voltage levels. The following table describes typical network levels and the corresponding parameterization.

Default reference system

Voltage level (id)	Nominal voltage (vNom)	Apparent power (sNom)
LV	0.4 kV	100 kVA
MV	10 kV	40 MVA
MV	20 kV	60 MVA
MV	30 kV	150 MVA
HV	110 kV	600 MVA
EHV	220 kV	800 MVA
EHV	380 kV	1000 MVA

Configuration of the reference system

To configure the reference system, the voltage levels listed in the table above must be selected and integrated into the reference system with the nominal apparent power (sNom), the nominal voltage (vNom), and the individual voltage level configuration (voltLvls) according to the example below. Each voltage level is composed of the identifier and the nominal voltage.

simona.gridConfig.refSystems = [
    {sNom = "100 kVA", vNom = "0.4 kV", voltLvls = [{id = "LV", vNom = "0.4 kV"}]},
    {sNom = "60 MVA", vNom = "20 kV", voltLvls = [{id = "MV", vNom = "20 kV"}]},
    {sNom = "600 MVA", vNom = "110 kV", voltLvls = [{id = "HV", vNom = "110 kV"}]},
    {sNom = "1000 MVA", vNom = "380 kV", voltLvls = [{id = "EHV", vNom = "380 kV"}]}
]
