A power plant comprising: a plurality of photovoltaic (PV) modules arranged in a first and a second region of the power plant, wherein the PV modules in the same region are electrically connected with each other and wherein the PV modules of the first region are electrically connected to a local grid of the power plant via a first converter, and the PV modules of the second region are electrically connected to the local grid via a second converter; and a wind turbine generator (WTG) which is arranged such that the WTG is able to cast a shadow over at least one of the PV modules; wherein the first region and the second region extend in a substantially radial direction away from the WTG such that at most one of the two regions is at least partially covered by the shadow of the WTG at any time.

A system and method for managing shadow flicker at a wind turbine site having at least one wind turbine includes determining, via a processor, a sun position of the wind turbine site. The method also includes receiving, via the processor, a spatial location of the at least one wind turbine with respect to at least one receptor. Further, the method includes determining, via the processor, whether shadow flicker is occurring at the at least one receptor based, at least in part, on the sun position and the spatial location of the at least one wind turbine. Moreover, the method includes implementing, via the processor, a corrective action for the at least one wind turbine when shadow flicker occurs at the at least one receptor to reduce the shadow flicker.

A controller for controlling the operation of a power plant, the power plant comprising a wind turbine and a solar power generator, the controller comprising: an input arranged to receive an input signal indicative of an operating parameter of the solar power generator; a shadow detection module arranged to monitor the operating parameter and to detect a shadow at least partially shading the solar power generator, the detected shadow being caused by a blade of the wind turbine; a shadow prediction module arranged to predict at least one subsequent blade shadow in dependence on the detected blade shadow; a command module arranged to determine a command signal for controlling the solar power generator based on the blade shadow prediction; and an output arranged to output the command signal to the solar power generator.

The detecting a shadow is determined by a modeling of at least a portion of a wind turbine. First and second sensors are arranged relative to the model such that the first sensor detects a light and the second sensor detects a shadow during the conditions where the shadow would be produced.

A method for detecting a shadow condition from a wind turbine and a system for detecting a shadow condition are provided. An atmospheric condition detected from an atmospheric condition detector is compared to a threshold. From the comparison a determination is made that the atmospheric condition is shadow producing. The shadow condition is detected using said determination.
