A method for controlling wind turbines of a wind farm is disclosed. The wind farm is positioned at a site which includes one or more turbulence generating structures, such as hills, valleys, trees or buildings. A wind direction at the site of the wind farm is detected, and one or more upstream wind turbines and one or more downstream wind turbines are identified, based on the detected wind direction, where each of the upstream wind turbines is arranged in front of one or more of the downstream wind turbines, as seen in the wind direction. If it is detected that turbulent wind conditions are occurring, based on measurements performed by the wind turbines of the wind farm, then at least one of the upstream wind turbines is controlled based on measurements performed by at least one wind turbine which is a downstream wind turbine relative to the upstream wind turbine.

A mesoscale data-based automatic wind turbine layout method and device. The method comprises: initially screening an input wind field region on the basis of input mesoscale wind map data by means of a wind speed limit value to obtain a first wind field region; re-screening the first wind field region on the basis of input terrain data by means of a slope limit value to obtain a second wind field region; and determining, by means of tabu search in which a target wind turbine count and the second wind field region are used as inputs, a wind turbine layout that optimizes an objective function, wherein the objective function is the sum of the annual energy production for wind turbine locations.

A method for controlling wind turbine farm level loads by control strategy through site-specific topology effects. The method involves the steps of: providing wind velocity data from wind sensors mounted on the wind turbines, the velocity data comprising wind speed and wind direction; providing wind velocity data from one or more reference sensors, the velocity data comprising wind speed and wind direction; binning the wind data according to wind speed and wind direction; identifying wind turbines in which the velocity data deviates from the reference; and calculating modified loads acting on the wind turbines where the velocity data deviates from the reference; whereby the control strategy and/or maintenance activities are revised. A method for extending (or reducing) life of a wind turbine, altering performance (increased Annual Energy Production, AEP) (operational), or reducing cost through structural material reduction (design) is further disclosed. The approach can be used for scheduling maintenance for wind turbines in a wind farm.

A power-generating apparatus includes a wind power-generator, a curtain-frame coupled to the wind power-generator, and at least one support-pole attachable to the curtain-frame. The power-generating apparatus is useful for being anchored along a shoreline above an expected storm-surge, and for generating renewable energy. The device is designed to withstand storm forces.

A wind farm comprising a number of wind turbines arranged on a ground comprising a first ground portion having a first ground surface and an outer periphery and a second ground portion having a second ground surface and surrounding the first ground portion. The first ground portion is covered with a reflective artificial covering to provide a reflecting surface having an albedo higher than the albedo of the second ground portion and thereby generating a lower temperature and a higher pressure in the first ground portion than in the second ground portion and a wind having a speed in a direction from the first ground portion towards the second ground portion. Some of the wind turbines are arranged in the second ground portion in such a distance from the periphery of the first ground portion that they are subjected to the wind coming from the first ground portion.

A tree power generation system, comprises one or more tree branch clasps, the one or more tree branch clasps to attach to branches of a tree and one or more power generators. The one or more wires couple the one or more tree branch clasps to the one or more power generators, wherein movement in the branches of the tree causes movement in the one or more wires and the power generator generates electrical energy. The two or more tree branch clasps may be attached to one tree branch.
