Patent number: 10404072Abstract: An energy storage system for renewable energy applications includes a renewable energy source, a bidirectional inverter connected an AC bus and a DC bus, an energy storage unit connected to the bidirectional DC/DC converter, and a control system comprising one or more controllers coupled to the bidirectional inverter and the bidirectional DC/DC converter. The bidirectional inverter is connected to the renewable energy source and a bidirectional DC/DC converter through the DC bus. The control system is configured to facilitate the operation of the bidirectional DC/DC converter and the bidirectional inverter. The energy storage system both stores energy from the renewable energy source and a utility grid, and also supplies power to the utility grid. The energy storage system is utilized in a method for supporting frequency regulation of a utility grid and a method for controlling an output power ramp rate for a renewable energy storage system.Type: GrantFiled: August 14, 2018Date of Patent: September 3, 2019Assignee: DYNAPOWER COMPANY LLCInventors: John C.

Patent number: 10374429Abstract: A power system having a plurality of power converters coupled together at a point of common coupling (PCC). The power converters are coupled to a load and provide a combined power converter output to the load. A switch is coupled in series between the PCC and an external grid. When the switch is closed, the power system is in a grid-tied configuration and when the switch is open, the power system is in a microgrid configuration. A control system coupled to the power converters enables the switch to open and close in response to a signal received from one or more sensors monitoring the external grid, enables the power converters to operate in a current control mode when the switch is closed, and transitions the power converters from grid-tied mode to microgrid mode and synchronize the power converters such that the converters share the load.Type: GrantFiled: October 23, 2017Date of Patent: August 6, 2019Assignee: DYNAPOWER COMPANY LLCInventors: Apurva Somani, John C.
