Abstract: A method for automatically controlling a renewable energy facility having a plurality of power sources includes operating, via a farm-level controller, the hybrid renewable energy facility at a first farm-level power set point. The method also includes modifying, via the farm-level controller, the first power set point to a second farm-level power set point. In response to modifying the first power set point to the second farm-level power set point, the method includes generating one or more power change requests for individual controllers of the plurality of power sources. Further, the method includes generating a power output via the plurality of power sources so as to transfer power generation from one of the plurality of power sources to another while minimizing the impact on farm-level production.

Abstract: A cooling system for cooling a temperature-dependent power device includes an active cooling device and a controller to generate and transmit a drive signal thereto to selectively activate the device. The controller receives an input from sensors regarding the cooling device power consumption and measured operational parameters of the power equipment—including the power device output power if the device is a power producing device or the power device input power if the device is a power consuming device. The controller generates and transmits a drive signal to the cooling device based on the cooling device power consumption and the measured power device input or output power in order to cause the active cooling device to selectively cool the heat producing power device. A net system power output or total system power input can be maximized/minimized by controlling an amount of convection cooling provided by the cooling device.

Abstract: A system and method are provided for controlling a wind farm. Accordingly, a demand signal is received from the electrical grid. The farm-level controller also receives a plurality of capability metrics from each wind turbines, which include, at least, a steady-state power availability, a transient power availability and a responsive capability of each wind turbine. The farm-level controller determines a power production capability profile for each wind turbine and determines the availability of each wind turbine to meet at least a portion of the demand signal based on the power production capability profiles. The farm-level controller also determines which portion of the demand signal to be satisfied by each wind turbine based on the availability and the power production capability for each wind turbine.

Abstract: A solar power conversion system includes a photovoltaic array having photovoltaic modules for generating direct current (DC) power. A power converter is provided in the system for converting the DC power to alternating current (AC) power. A transformer is coupled between the power converter and a power grid for transmitting the AC power to the power grid. The transformer is connected to the power grid at the point of common coupling (PCC) and to the power converter at output terminals. A reactance estimation module is provided in the system for estimating a short circuit reactance at PCC based on a small change in a measured voltage at output terminals with respect to a small change in a measured reactive power at the output terminals. Further, a maximum reactive power estimation module estimates a maximum reactive power based on the estimated reactance, the measured voltage at output terminals, and the measured reactive power at the output terminals. A controller in the system generates switching command signals for the power converter based on the measured voltage at output terminals and the estimated maximum reactive power.

Abstract: A power system includes a first power asset include a first power source and a first power controller. The first power controller includes a first filter configured to receive an error amount at a first frequency range and a second power controller includes a second filter configured to receive the error amount at a second frequency range. The first power controller is configured to instruct the first power source to produce a first amount of power, adjust the first amount of power based on the error amount received by the first filter until the error amount received is substantially zero. When the error amount received is substantially zero, the first power controller is configured to determine a first desired operating amount of power based on the first power source, and adjust the first amount of power based on the first desired operating amount of power.
