US 12,700,815 B2 · Systems and methods for grid forming control

Abstract

Systems, methods, and media for grid forming control having balancing feedback across the phases are provided. The grid forming control can include phasor determination configured to, for each of the plurality of phases, receive a frequency reference and determine an active and reactive power for the phase based on an electrical measurement for the phase and the frequency reference, GFM control configured to, for each of the plurality of phases, determine the frequency reference based on the active power for the phase and balancing feedback across the plurality of phases and determine a voltage magnitude reference for the phase based on the reactive power for the phase and balancing feedback across the plurality of phases, and a control loop configured to, for each of the plurality of phases, determine a control signal for a power converter based on the determined voltage magnitude reference for the phase.
