Integrate state estimation fictitious injections

[rcourtier]

Describe the current behavior

IIDM supports modeling of fictitious injections at node/breaker ans bus/branch topology levels:

• From VoltageLevel.NodeBreakerView interface:
  • getFictitiousP0(int node)
  • setFictitiousP0(int node, double p0)
  • getFictitiousQ0(int node)
  • setFictitiousQ0(int node, double q0)
• From Bus interface:
  • getFictitiousP0()
  • setFictitiousP0(double p0)
  • getFictitiousQ0()
  • setFictitiousQ0(double q0)

Important

These fictitious injections represent the complement of the telemeasures typically after a state estimation. It does not represent "corrections" to a loadflow computation so that the sum of injections on a bus is null.

Currently, these ficitious injections are not fully handled: modeling and serialization is supported, but simulation, visualization and import/export aren't.

Describe the expected behavior

The fictitious injections should be taken into account in the load flow computation:
powsybl-open-loadflow #1114

The fictitious injections should be suitably represented in the single line diagrams:
powsybl-diagram #741

The fictitious injections should be exported to CGMES non conform loads:
powsybl-core #3608

Describe the motivation

The full support of SE fictitious injections would allow to make a proper distinction between real energy consumers and fictitious ones as seen by the state estimator.
