An automatic tracking solar photovoltaic power generation system and method

Abstract

The invention proposes an automatic tracking solar photovoltaic power generation system and method. The solar photovoltaic power generation system includes a plurality of solar photoelectric conversion panels, a tracking control device that controls the state change of the solar photoelectric conversion panels, and a plurality of remote terminal units in different geographical directions. The unit communicates with the tracking control device; after the on-site edge computing unit receives the weather parameter information sent by the remote centralized control platform and the site status sensing signal information collected by the multiple remote terminal units, the tracking control device A tracking control instruction is generated; based on the tracking control instruction, the state change of the solar photoelectric conversion board is controlled; the state change includes an angle change and a height change of the solar photoelectric conversion board. The technical scheme of the invention can acquire accurate control parameters to the greatest extent, thereby realizing accurate automatic tracking control.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation control, and in particular relates to an automatic tracking solar photovoltaic power generation system and method. Background technique [0002] Solar energy is a clean and renewable energy with large radiation, wide distribution and long availability. Therefore, solar power generation technology has been comprehensively researched and developed, but due to the shortcomings of weak solar energy, poor continuity, and instability, the efficiency of solar power generation is low and the power generation is unstable. At present, when using solar photovoltaic power generation, many solar panel arrays are basically fixedly installed in one direction, which cannot guarantee the vertical irradiation of sunlight on the solar panel, so that the solar battery cannot make full use of solar energy resources, and the power generation efficiency is low. [0003] A feasible way to solve thi...

Problems solved by technology

The closed-loop tracking system can track the sun more accurately, while the open-loop tracking system often causes errors to accumulate during the tracking process; Or the control strategy is effective. If the data collected by the relevant parameter sensors on site is not accurate enough, the obtained control strategy will not be able to achieve effective tracking control, but will reduce the power generation efficiency.
