  • Publication number: 20200119584
    Abstract: Computer software and a system are disclosed to provide group control and network operations to/for a multiplicity of distributed energy storage units. The group control software and system can connect multiple individual distributed energy storage units and operate those units in synchronicity to create a large virtual energy storage device. Methods of controlling the distributed energy storage units include: a browser-based online user portal, or network-based, system-to-system protocols by third-party operation controllers.

  • Publication number: 20140142778
    Abstract: The present invention provides a software and system to provide group control and network operations to/for a multiplicity of distributed energy storage units. In particular, the group control software and system connects multiple individual distributed energy storage units and operates those units in synchronicity to create a large virtual energy storage device. This group control system includes two methods of controlling the distributed energy storage units: through a browser-based online user portal, or though network-based, system-to-system protocols by third-party operation controllers.

  • Publication number: 20120059527
    Abstract: The present invention provides a distributed energy storage system, and applications thereof. In an embodiment, the distributed energy storage system includes power units, wherein each power unit has a multi-cell battery; a battery manager that monitors battery cell voltages and temperatures; and a controller. The controller provides a first control signal that causes the power unit to store energy in the battery and a second control signal that causes the power unit to generate an alternating current. A server in communication with each of the power units stores data collected from the power units about the batteries and analyzes the data to determine how much available energy is stored in the batteries that can be used to alter a load demand of a power network. In an embodiment, the batteries are lithium ion batteries capable of storing at least ten kilowatthours of energy.

  • Publication number: 20200125076
    Abstract: A computer implemented method at an energy management system (EMS) controller apparatus for automatic generation of a SCADA (supervisory control and data acquisition) slave interface for an energy management system (EMS), includes storing a SCADA configuration file mapping SCADA data points to EMS data objects; providing the EMS data objects coded in statically typed programming language; providing site configuration information of the energy management system (EMS); scanning, by an object access framework (OAF), EMS data objects with EMS annotations and combining them with the site configuration information to generate an object binding repository (OBR); and compiling the SCADA configuration file to combine the SCADA data points mapping with the object binding repository to generate SCADA bindings information as part of the SCADA slave interface for the energy management system (EMS).
