1. A system comprising:

  • a plurality of power generators configured to be connected to transmission lines of an existing power grid;

    a plurality of synchronization modules, each synchronization module corresponding to one of the plurality of power generators and configured to output a control signal to adjust a frequency of a respective power generator to correspond with the frequency of the existing power grid; and

    a central controller in communication with the plurality of synchronization modules, the central controller configured to determine a propagation delay with respect to each synchronization module, the propagation delay being a measure of time for a signal to propagate from a respective synchronization module to the central controller;

    wherein the central controller is further configured to send a control signal to each synchronization module to control when each synchronization module connects the respective power generator to the existing power grid based on the determined propagation delay signal.
