| For now the only VariationType handled by OpenRAO is "ABSOLUTE" : the min/max admissible set-points of the HVDC. | ||
| **An HVDC Range Action is modelled by an Injection range Action** (the HVDC line is disconnected and replaced by two injections, one on each side of the line, with opposite keys of 1 and -1). |

This is not even a part of the code that you modified, but I noticed that it is not precise enough: the HVDC line is not disconnected, the reality is that an HVDC line cannot be modeled in UCTE format, so an equivalent model is used: the HVDC is represented through two injections (and other elements, cf GridCapa doc), this is whoy the HVDC range action is modelled by an Injection Range actions.

| An HVDC Range Action moves the active setpoint field of the HVDC line. When a line is in AC Emulation mode, applying an **HVDC Range Action** has no effect because the line cannot be directly controlled via its active power setpoint. |

I would rephrase this, to clarify if you are talking about an "HVDC Range Action" in OpenRAO (which is an action that doesn't work on a line in AC emulation), or a general "HVDC Range Action" (which is a theoretical element, that could also contain implicitly the switch from AC emulation to fixed setpoint mode).
My concern here is that in the beginning of the page, the reader might feel that it is impossible to use a remedial action that optimises the setpoint on an HVDC line in AC emulation - which is not true, as explained later on the page.

I tried adding something to clarify this point. What do you think ?
