Remedial actions are actions that are applied when limit violations occur. Supported actions are:

- Open or close a switch
- Open or close a terminal
- Change the tap of a tap changer (phase or ratio)
- Change the active and/or reactive power of a load (by setting the values, or defining changes in value or percentage)
- Change the section of a shunt compensator
- Change the regulation status of a tap changer
- Change `targetP`, `targetQ`, regulation status and `targetV` of a generator
- Change the regulation mode of a static var compensator and its associated set point.
- Enabled or disabled AC emulation for HVDC line (with the possibility to change `P0` and `droop` for AC emulation and
- `LoadAction` Change the relative of absolute `P0` and/or `Q0` of a load
- `DanglingLineAction` Change the relative of absolute `P0` and/or `Q0` of a dangling line
- `SwitchAction` Open or close a switch
- `TerminalsConnectionAction` Open or close a terminal
- Change the tap of a tap changer (phase `PhaseTapChangerTapPositionAction` or ratio `RatioTapChangerTapPositionAction`)
- `PercentChangeLoadAction` Change the active and/or reactive power of a load (by setting the values, or defining changes in value or percentage)
- `ShuntCompensatorPositionAction` Change the section of a shunt compensator
- Change the regulation status of a tap changer (phase `PhaseTapChangerRegulationAction` or ratio `RatioTapChangerRegulationAction`)
- `GeneratorAction` Change `targetP`, `targetQ`, regulation status and `targetV` of a generator
- `StaticVarCompensatorAction` Change the regulation mode of a static var compensator and its associated set point.
- `HvdcAction` Enabled or disabled AC emulation for HVDC line (with the possibility to change `P0` and `droop` for AC emulation and
active power set point and converter mode for set point operating mode)
- Change the interchange target of an area by specifying a new interchange target in MW.
- `AreaInterchangeTargetAction` Change the interchange target of an area by specifying a new interchange target in MW.

- curative: these actions are implemented after a violation occurs, for example, if the flow of the monitored line is
greater than `100%`.

Note: you can find the current list of remedial actions implemented in the PowSyBl Open Load Flow security analysis provider in the [PowSyBl Open Load Flow documentation](inv:powsyblopenloadflow:*:*#security/inputs).

### Conditions

Actions are applied if a condition is met. The conditions can be diversified and extended in the future:
