Classification: CPC H  G | IPC G  H

Claim 0:
1. A method for controlling a power plant including a plurality of generator units that are connected to an electrical grid at a single shared connection point, the method comprising:
setting a reference frame for the plurality of generator units having a first axis and a second axis;
measuring a demand of the electrical grid at the shared connection point, wherein the demand of the electrical grid comprises:
an active power demand,
a reactive power demand, and
a voltage magnitude to supply to the electrical grid per a grid code;

determining an active current required at the shared connection point based on the active power demand and the voltage magnitude;
determining a reactive current required at the shared connection point based on the reactive power demand and the voltage magnitude;
transforming the active current required and the reactive current required at the shared connection point to the reference frame where the first axis defines a first current set point and the second axis defines a second current set point; and
dispatching at least one of the first current set point or the second current set point to generator controllers associated with each generator unit of the plurality of generators units.
