  • Patent number: 10411469
    Abstract: Systems and methods to incorporate control of reactive power produced by a variable reactive power output inverter that is installed in an existing installed power generation site. A reactive power output command value limiter is integrated with the variable reactive power output inverter. The reactive power command limiter iteratively: receives a reactive power command value, determines a threshold reactive power output value based on present real power output, determines that the reactive power command value exceeds the threshold reactive power output value, changes, based on the determining that the reactive power command value exceeds the threshold reactive power output value, the reactive power output command input value to a limited value reactive power output command that is one of equal to or less than the threshold reactive power output value, and outputs the limited value reactive power output command to the variable reactive power output inverter.

  • Patent number: 9660448
    Abstract: A method of configuring a renewable energy curtailment and control system uses a master controller and a plurality of controllers configured to control a cluster of renewable energy resources to deliver predetermined amounts of actual power and reactive power to a point of interconnect with a grid in accordance with contractual requirements with users of electrical power while reducing reactive power flow between renewable resources in the cluster.

  • Patent number: 9077204
    Abstract: The present invention includes a system and method for generating, controlling and storing dispatchable renewable energy. The system may include one or more wind power generation facilities and one or more solar power generation facilities to generate power that can be stored by one or more storage facilities. The power can be supplied to a power grid at a level determined by actual or predicted weather conditions, based on variable power demands. The power generated by the renewable energy sources may be combined with power generated by conventional power generation facilities to provide power in a dispatchable manner.

  • Patent number: 8805596
    Abstract: The present invention includes a Computer Assisted Reset (CAR) system that allows a central operations team to remotely reset turbine faults across multiple wind turbine platforms and SCADA systems with a single interface. The system also allows automatic resets to occur. One aspect of the invention includes a Modbus to OPC Translator. The translator permits the implementation of a system where a PLC located at wind turbine control sites can accept control messages or commands organized or formatted in accordance with the Modbus protocol and sent over an Internet Protocol connection, with the translator receiving the requests through the PLC and generating an appropriate OPC (“OLE Process Control”) request. The OPC request may then be passed onto a corresponding OPC server residing in the SCADA system for each wind turbine control site.
