Photovoltaic building intelligent monitoring method and system for real-time power generation adjustment

Abstract

The invention discloses a photovoltaic building intelligent monitoring method and system for real-time power generation adjustment, and relates to the technical field of photovoltaic buildings, and the method comprises the following steps: obtaining the illumination dynamic distribution data of the surface of a photovoltaic module in real time through an image collection device; shielding feature extraction is carried out on the illumination dynamic distribution data, and a photo-thermal distribution diagram reflecting the surface of the photovoltaic array is generated; analyzing the photo-thermal distribution diagram based on the edge calculation nodes, constructing a mapping relation between the shielding position and power attenuation, and dynamically adjusting a power output optimization strategy of the photovoltaic sub-array according to the mapping relation; and training a prediction model by using historical occlusion data and real-time power generation data, and pre-triggering an adjustment operation of a power optimization strategy. According to the invention, the sub-arrays with strong power generation capability can output more power, and the sub-arrays with weak power generation capability can output relatively less power, so that the power generation efficiency of the whole photovoltaic system under complex illumination conditions is effectively improved, and the power generation loss caused by shadow shielding is reduced.
