Abstract

The invention provides a two-sided photovoltaic cell panel tracking control method and system. The method comprises the steps of S1, performing detection on a photovoltaic power generation region to obtain topographic feature data, earth surface light reflection feature data of the photovoltaic power generation region and power generation region irradiation data; S2, establishing a three-dimensional photovoltaic simulation map according to the topographic feature data, the earth surface light reflection feature data and a preset photovoltaic power station configuration graph; S3, creating a back surface irradiation reflection model according to the three-dimensional photovoltaic simulation map, the power generation region irradiation data, the system parameters of the photovoltaic power station, and the back surface irradiation data of a two-sided photovoltaic cell panel; and S4, controlling the two-sided photovoltaic cell panel to perform photovoltaic tracking according to a trackingmode corresponding to the current weather type by combination of the back surface irradiation reflection model and the collected front surface irradiation data of the two-sided photovoltaic cell panel. By virtue of the control method and system, photovoltaic data can be obtained to the maximum degree, and the power generation capability of the two-sided photovoltaic cell panel is improved.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a tracking control method and system for double-sided photovoltaic panels. Background technique [0002] With the popularization of the concept of low-carbon recycling, clean energy has attracted more and more attention. Clean energy such as wind power, photovoltaic power, and tidal power has brought good news to people. [0003] Due to the lack of effective collection of information on the back of bifacial modules, the current bifacial module power station projects basically use the tracking mode of single-facial modules for daily tracking. This tracking method cannot effectively utilize the double-sided power generation capacity of the bifacial module, resulting in a huge waste of the backside power generation capacity of the bifacial module. And in some special weather conditions (such as cloudy, rainy, cloudy, snowy, windy), etc., the tracking method of photovol...
