Patent number: 12034302Abstract: Methods and systems are provided for optimizing energy management of an energy resource site. For instance, a hierarchical energy management system can provide optimized management of energy resource sites with large numbers of energy resources. In particular, the hierarchical energy management system can effectively control energy resources by allocating functionality using different tiers. For instance, one or more energy resources devices can comprise the lowest tier of the hierarchical energy management system. The next tier of the hierarchical energy management system can comprise one or more controllers that can manage the energy resource devices. The next tier of the hierarchical energy management system, a resource manager, generally manages the set of controllers.Type: GrantFiled: February 14, 2022Date of Patent: July 9, 2024Assignee: Doosan GridTech, Inc.Inventors: Nate Diamond, Sam Skrivan, Jacob Hansen, Krysta Suzanne Yousoufian, Paydon Wilinchery

Patent number: 11258266Abstract: The disclosed system provides an adaptive control system technique generally related to distributed energy resources (DERs) located in distribution circuits. More specifically, the system technique relates to a DER with both active and reactive generation capability. In an embodiment, the system measures a voltage phase angle and a current phase angle of distribution feeder circuit, and measures a voltage value output by a power converter. The system calculates an active power setpoint value and a reactive power setpoint value of the power converter based on the measured voltage value, and the measured voltage phase angle and current phase angle. The system then sets the active and reactive power setpoint values on the power converter. The disclosed system automatically adjusts the setpoints to real-time load characteristics of the distribution feeder circuit, increases distribution feeder hosting capacity, and enables DERs to integrate in distribution feeders more efficiently.Type: GrantFiled: May 23, 2018Date of Patent: February 22, 2022Assignee: Doosan GridTech, Inc.Inventors: Farshid Shariatzadeh, Troy Nergaard, David Kaplan

Patent number: 9537318Abstract: An energy storage system includes modular energy storage equipment that may be connected to an external system, such as a power grid. In at least one embodiment, the energy storage system includes a power transfer control system comprising a power transfer network and a processing module or controller. The power transfer network has a first interface coupleable to one or more energy storage units and a second interface coupleable to one or more power conversion units. One or more conductors in the power transfer network are selectively coupleable to the first interface and the second interface for transferring power between the energy storage units and the power conversion units based at least in part on information indicating a power or energy supply or demand of an external system or information indicating an amount of energy stored in the energy storage units. The energy storage system is scalable for different implementations.Type: GrantFiled: November 2, 2012Date of Patent: January 3, 2017Assignee: Doosan GridTech, Inc.Inventors: David L. Kaplan, Joshua I. Kaplan, Gregory P. Darlington
