Abstract: A load is powered by a power source and a capacitive element in series such that the voltage provided to the load is the sum of the voltages of the power source and the capacitive element. A power converter imposing a limit on a flow of current through at least a portion of the power converter is coupled to the power source and the capacitive element, and selectively causes the capacitive element to either be charged or to discharge depending on the amount of current drawn by the load. As the capacitor discharges, the power source is permitted to supply a relatively higher amount of current to the load.

Abstract: Systems, apparatus, and methods are provided for maintaining the state of charge of energy storage devices such as batteries, flywheel, capacitors, or other technologies that are energetically coupled with the electricity grid to support ancillary services. To reliably respond to requests to regulate the grid, the charge on the energy storage device is sustained or restored to a specified range in a manner that optimizes the readiness of the energy storage device to supply ancillary services in light of the condition of the grid. A state of charge (SOC) of the energy storage device and the grid frequency may be monitored. When a request from the operator to regulate the grid frequency is not being serviced, the charge of the energy storage device may be increased or decreased so that the charge may be sustained within the specific range. Once the SOC falls outside of the first range, charge may be added to or removed from the energy storage device when the grid frequency has appropriate values, e.g. if the grid frequency is respectively above a first setpoint or below a second setpoint.
