Abstract:
An intelligent coactive converter comprising:an input line configured to receive electric power produced by a renewable facility, said electric power being inadequate to be applied directly to a standard frequency AC power grid due to at least one of insufficient voltage stiffness, and excessive power variability; an output line configured to deliver enhanced electric power to said standard frequency AC power grid at, at least, one point-of-connection in a grid area-of-connection, said enhanced electric power being enhanced with regard to at least one of voltage stiffness and power variability with respect to a delivery to said standard frequency AC power grid of said electric power from said renewable facility; a constant-frequency output, rotating AC machine, yM, electrically coupled to said output line a controller configured to control an operational state of said yM, and corresponding predetermined amounts of active and reactive power provided by, or consumed by, said yM to the standard frequency AC power grid so as to prime the electric power from the renewable facility and enable a delivery of the enhanced electric power to said at least one point-of-connection.
