  • Method and system for power grid voltage regulation by distributed energy resources
    Patent number: 10910841
    Abstract: A system and method for regulating a voltage at a point of common coupling (35) (PCC) of a distributed energy resource farm (1) connected to an electrical power grid (37). The distributed energy resource farm includes a plurality of connected distributed energy resources (2, 3) each supplying a terminal voltage. The system includes a component (50) for measuring a PCC voltage at the PCC, and another component (39, 41) for determining a first value based on a relationship between a scheduled voltage at the PCC and the measured PCC voltage relative to a dead band voltage region (66). A further component (39, 41) regulates the voltage at the point of common coupling by controlling the terminal voltage of each one of the plurality of distributed energy resources in response to the relationship between the scheduled voltage and the measured voltage at the PCC.
