  "textContent": "A method of controlling an islanded power grid using multiple power generating units operates one of the power generating units in an isochronous mode to perform frequency control on the power grid and operates the other power generating units in droop mode to provide the overall instantaneous power needed on the grid. The method provides better overall efficiency of the power generating system while still enabling robust frequency control by determining the power generating unit to operate in the isochronous mode based on a predicted load demand or load demand change over a near-term time horizon. The method implements an optimization routine that determines the distribution of the power generating load across the power generating units in an efficient or optimal manner, and then selects the isochronous power generating unit as the power generating unit that has the highest capacity with the needed upward and downward reserve for making frequency control movements during the near-term time horizon.",
