摘要:
A method for using excess energy generated by a renewable power generation system including at least one renewable power generator to treat organic waste material to generate crude oil. The method includes providing a renewable power generation management system operatively coupled to the renewable power generation system. The renewable power generation management system receives operational data from a pump load operatively coupled to the renewable power generator, and/or operational data from an electrical grid operatively coupled to the renewable power generator. Based at least in part on anticipated energy requirements, excess energy is supplied to the pump load to facilitate treating the organic waste material to generate crude oil.

A system for controlling a microgrid includes microgrid assets and a tieline for coupling the microgrid to a bulk grid; and a tieline controller coupled to the tieline. At least one of the microgrid assets comprises a different type of asset than another one of the microgrid assets. The tieline controller is configured for providing tieline control signals to adjust active and reactive power in respective microgrid assets in response to commands from the bulk grid operating entity, microgrid system conditions, bulk grid conditions, or combinations thereof.

An air distribution system for use with a wind turbine. The wind turbine includes a nacelle that is coupled to a tower and a rotor that is rotatably coupled to the nacelle with a rotor shaft. The rotor includes at least one rotor blade that is coupled to a hub. The air distribution system includes a conduit that is defined within the rotor shaft. The conduit provides flow communication between the nacelle and the rotor. An air-flow control assembly is coupled in flow communication with the conduit. The air-flow control assembly is configured to selectively channel air from the nacelle to the rotor and from the nacelle to ambient air.
摘要:
A method and apparatus for integrating Sudo rules into a Lightweight Directory Access Protocol (LDAP) repository. An LDAP directory server receives a request to add a sudo rule to the LDAP repository. The sudo rule defines at least one sudo command and one or more entities associated with the execution of the sudo command. The LDAP directory server creates an LDAP entry for the sudo rule, and links in the LDAP entry of the sudo rule an LDAP entry of the sudo command and LDAP entries of the entities associated with the execution of the sudo command.
摘要:
A method of power system dispatch control solves power system dispatch problems by integrating a larger variety of generation, load and storage assets, including without limitation, combined heat and power (CHP) units, renewable generation with forecasting, controllable loads, electric, thermal and water energy storage. The method employs a predictive algorithm to dynamically schedule different assets in order to achieve global optimization and maintain the system normal operation.

A power generation system having a wind turbine blade assembly, a generator mechanically coupled to the blade assembly, and a power converter coupled to the generator is provided. An energy storage device and a bidirectional converter coupling the energy storage device to the power converter are also provided in the system. An inertia controller is provided for generating a first transient signal to regulate active power from the wind turbine system when a power grid signal is outside of a respective signal range. The system further includes an energy storage controller for providing a second transient signal to the bidirectional converter to regulate a power to or from the energy storage device based upon the first transient signal, power generating system conditions or combinations thereof.

A method of providing reactive power support is proposed. The method includes detecting at least one of a plurality of network parameters in a distributed solar power generation system. The generation system includes a plurality of photovoltaic modules coupled to a grid via inverters. The method further includes sensing a state of the photovoltaic modules coupled to the distributed solar power generation system and determining a reactive power measure based upon the sensed state and the detected network parameters. The reactive power measure is used to generate a reactive power command. The reactive power command is further used to compensate reactive power in the distributed solar power generation system.
摘要:
A photovoltaic (PV) control system generates a power output rate control signal based on a monitored rate of change of collective power output generated via a plurality of PV subsystems and a desired collective output power change rate for the plurality of PV subsystems and communicates the power output rate control signal to the plurality of PV subsystems to control a rate of change of one or more operating parameters of individual PV subsystems in order to control a rate of change of collective output power of the plurality of solar PV subsystems.
