Why Steady State Hypothesis?

Initially Topology and State Variables used both forOutput Input

Didn’t work, Power Flow solutions driftedNeed to remember the starting conditions

Steady State Hypothesis solved this

State Variables AC Profile Sign Conventions

SvPowerFlow Load sign convention is used, i.e. positive sign means

flow out from a TopologicalNode (bus) into the conducting equipment.

SvInjectionThe power injected into the bus in addition to injections

from equipment terminals. Positive sign means injection into the TopologicalNode (bus).

• The active power slack is specified by using the multiple generator slack participationfactor in CIM. In case GeneratingUnit.normalPF is set to one and all other generating units have a zero participation factor the GeneratingUnit which has normalPF equal to one will be the active power slack for the ControlArea to which it belongs. In case multiple generators all these GeneratingUnit(s) have non-zero normalPF, but there must be one GeneratingUnit per control area that have maximum participation factor (GeneratingUnit.normalPF).

• In case of exchange of steady state hypothesis (non-solved model) or solved model normalPF can be non-zero only for generators which are in operation (participate in the load flow).

• In case of exchange of steady state hypothesis (non-solved model, i.e. SV profile is not exchanged) the tools should assign the slack node.

EquivalentInjection.regulationStatus and EquivalentInjection.regulationTarget are required attributes if the EquivalentInjection is connected to a non-Boundary node.
