At this time, the precise tracking of the sun by photovoltaic modules is basically meaningless. If the real-time tracking of the sun is purely relying on the use of photodetectors in the existing technology, the increase in power generation will not only bring little benefit, but will even occur due to the loss of the actuator itself. Negative yield scenario for generation growth

The invention discloses a photovoltaic tracking power generation method based on GPS positioning. By using the method, a GPS positioning module is used to detect and calculate a sun position. A main control module makes a photovoltaic assembly rotate to a position which is aligned to the sun position at intervals of preset time t0 according to sun position information calculated by the GPS positioning module. A feedback tracking module calculates a power increment rate factor of the photovoltaic assembly at moments before and after rotation motion. The main control module controls and changes precision of sun tracking of an optical sensor on the photovoltaic assembly according to the calculated power increment rate factor so that the precision of the sun tracking of the photovoltaic assembly can be changed according to intensity of a direct radiation portion in sunshine. Under the condition of maintaining and acquiring a high electric energy production gain, losses of a system caused by the tracking are well avoided.
Description
technical field [0001] The invention relates to the field of solar power generation, in particular to a photovoltaic power generation method based on GPS positioning. Background technique [0002] In the photovoltaic power generation system of the prior art, when the sun is completely blocked by thick clouds, 100% of the solar radiation energy received on the ground is scattered radiation. At this time, the precise tracking of the sun by photovoltaic modules is basically meaningless. If the real-time tracking of the sun is purely relying on the use of photodetectors in the existing technology, the increase in power generation will not only bring little benefit, but will even occur due to the loss of the actuator itself. Negative yield scenario for generation growth. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a photovoltaic power ge...
