3results about How to "Avoid affecting power generation efficiency" patented technology

The invention belongs to the technical field of power generation power prediction, and particularly relates to an intelligent prediction method for photovoltaic short-term power generation power combination, which comprises a plurality of photovoltaic modules and a power generation power combination prediction system, and air cleanliness testers are arranged around the plurality of photovoltaic modules. An air dust detection module is arranged in the air cleanliness tester, and the power generation power combined prediction system comprises an intelligent network end module, an intelligent prediction module and a block chain center module. The intelligent network end module comprises a haze unit, a wind power unit and a geographical environment unit, the intelligent network end module is electrically connected with the intelligent prediction module, and the intelligent prediction module is electrically connected with the block chain center module. And due to the fact that dust and dirt are accumulated on the photovoltaic surface, the sunlight absorption capacity of the photovoltaic system is reduced, and predicted generated power data are not accurate.
