Description

There is ambiguity in the usage and definition of the following attributes
GeneratingUnit.maxOperatingP
GeneratingUnit.minOperatingP
EquivalentInjection.minP
EquivalentInjection.maxP
ExternalNetworkInjection.minP
ExternalNetworkInjection.maxP
EquivalentInjection.minQ
EquivalentInjection.maxQ
ExternalNetworkInjection.minQ
ExternalNetworkInjection.maxQ

GeneratingUnit and the injections can operate both in generator and in motor mode. It is not clear what is the sign convention for the limits. Is it positive when generating and negative when consuming? If yes a GeneratingUnit of type motor needs to have its minOperatingP and maxOperatingP negative. However do we require that abs(minOperatingP) is < abs(maxOperatingP)? If not doing this one can do maxOperatingP=-5 > minOperatingP=-100 which will need to be most probably imported in an application as Pmax=100 and Pmin=5, meaning we do not have 1:1 mapping in the sense of meaning maxOperatingP and minOperatingP.

Whatever the solution is this needs to be compatible with the understanding of ReactiveCapabilityCurve and xvalue there in case of motor operation

Similar clarification is necessary for EquivalentInjection and ExternalNetworkInjection where we do not have the operating mode in EQ, but we do have limits there.
