One example includes a utility power system. The system includes a power generator system, the power generator system comprising a generator step-up (GSU) transformer and a power generator. The power generator can be configured to provide generator power to a power transmission system via the GSU transformer in a feedback manner based on a predetermined setpoint. The system further includes a voltage droop compensation controller configured to monitor the generator power at a high-side of the GSU transformer and to adjust the predetermined setpoint based on the monitored generator power to substantially mitigate circulating currents.

Voltage droop compensation for a utility power system

A method of creating an interconnected combination of a stored energy electric generation system to a variable electric power generation system, said combination, and a method of operating same. A stored energy electric generation system is added to a variable output electric power generation system. An input/output of the stored energy electric power generation system is connected to a power output of the variable electric power generation system and an indicator of power flow level through the power input/output of the stored energy electric power generation system is provided to a controller of the variable electric power generation system. The controller is configured to adjust the output power of the variable electric power generation system based on the indicator of the present stored energy system electric power flow level and a present site output electric power level.

Systems and methods enable yaw offsets on wind turbines in a wind farm. A wind turbine yaw controller receives a present wind direction signal from a local wind direction sensor and aligns the wind turbine in a substantially perpendicular direction based upon the present wind direction signal. A yaw controller is retrofitted between the wind direction sensor and the yaw controller to provide an adjusted wind direction signal to the yaw controller based upon the present wind direction signal and a yaw offset signal. An offset table relating yaw offsets with wind direction signal values may be stored locally at a wind turbine or at a site controller in communication with the wind tribune. Each wind turbine in the wind farm may be retrofitted with the yaw controller to enhance the power output of the wind farm by adjusting the wake effect between wind turbines of the wind farms.

One example includes a wind farm power control system. The system includes a wind farm controller configured to monitor a power characteristic at a high-side of a generator step-up (GSU) transformer. The high-side of the GSU transformer is coupled to a point-of-interconnect (POI) that provides power from the wind farm to a power grid. The system also includes an automatic voltage regulator (AVR) configured to monitor a voltage of a power bus associated with a low-side of the GSU transformer, the power bus being provided power from a plurality of feeder groups. Each of the plurality of feeder groups includes a plurality of wind turbines. The AVR can be further configured to regulate the power characteristic at the high-side of the GSU transformer to within a predetermined range of amplitudes based on the voltage of the power bus.

Wind farm power regulation

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.
