EnergySource
Class Description​
A generic equivalent for an energy supplier on a transmission or distribution voltage level.
Attributes​
| Name | Type | Description |
|---|---|---|
| activePower | ActivePower | High voltage source active injection. Load sign convention is used, i.e. positive sign means flow out from a node. Starting value for steady state solutions. |
| isExternalGrid | Boolean | True if this energy source represents the higher-level power grid connection to an external grid that normally is modelled as the slack bus for power flow calculations. |
| pMax | ActivePower | This is the maximum active power that can be produced by the source. Load sign convention is used, i.e. positive sign means flow out from a TopologicalNode (bus) into the conducting equipment. |
| pMin | ActivePower | This is the minimum active power that can be produced by the source. Load sign convention is used, i.e. positive sign means flow out from a TopologicalNode (bus) into the conducting equipment. |
| r | Resistance | Positive sequence Thevenin resistance. |
| r0 | Resistance | Zero sequence Thevenin resistance. |
| r0_max | Resistance | Maximum zero sequence Thevenin resistance. |
| r0_min | Resistance | Minimum zero sequence Thevenin resistance. |
| r_max | Resistance | Maximum positive sequence Thevenin resistance. |
| r_min | Resistance | Minimum positive sequence Thevenin resistance. |
| reactivePower | ReactivePower | High voltage source reactive injection. Load sign convention is used, i.e. positive sign means flow out from a node. Starting value for steady state solutions. |
| rn | Resistance | Negative sequence Thevenin resistance. |
| rn_max | Resistance | Maximum negative sequence Thevenin resistance. |
| rn_min | Resistance | Minimum negative sequence Thevenin resistance |
| voltageAngle | AngleRadians | Phase angle of a-phase open circuit used when voltage characteristics need to be imposed at the node associated with the terminal of the energy source, such as when voltages and angles from the transmission level are used as input to the distribution network. The attribute shall be a positive value or zero. |
| voltageMagnitude | Voltage | Phase-to-phase open circuit voltage magnitude used when voltage characteristics need to be imposed at the node associated with the terminal of the energy source, such as when voltages and angles from the transmission level are used as input to the distribution network. The attribute shall be a positive value or zero. |
| x | Reactance | Positive sequence Thevenin reactance. |
| x0 | Reactance | Zero sequence Thevenin reactance. |
| x0_max | Reactance | Maximum zero sequence Thevenin reactance. |
| x0_min | Reactance | Minimum zero sequence Thevenin reactance. |
| x_max | Reactance | Maximum positive sequence Thevenin reactance. |
| x_min | Reactance | Minimum positive sequence Thevenin reactance. |
| xn | Reactance | Negative sequence Thevenin reactance. |
| xn_max | Reactance | Maximum negative sequence Thevenin reactance. |
| xn_min | Reactance | Minimum negative sequence Thevenin reactance. |
