Abstract

The invention discloses a method for tracking a maximum power point of a solar street lamp based on cloud evolution. The method comprises the following steps: setting a set iteration number needing to carry out the cloud evolution and a cloud variation algebraic threshold in the cloud evolution on a controller; randomly generating a population of solar cells; obtaining a predetermined number of individuals in the population according to the power of the individuals from large to small, and carrying out cloud evolution calculation to obtain an updated population; carrying out cloud evolution update on the individuals in the updated population; when the evolution algebra of the cloud evolution update is less than the cloud variation algebraic threshold, updating the cloud evolution update individuals again by adopting the cloud evolution; when the evolution algebra of the cloud evolution update is less than the set iteration number and reaches or exceeds the cloud variation algebraic threshold, carrying out a cloud variation operation on the cloud evolution update individuals, and adopting the cloud evolution to update the obtained individuals of a variant population; and when the evolution algebra of the cloud evolution update reaches or exceeds the set iteration number, obtaining the maximum output power point of the solar cells. By adopting the method disclosed by the invention, the maximum power point of the solar street lamp can be accurately tracked.

Description

technical field [0001] The present invention relates to the technical field of tracking and controlling the power of solar street lamps, and more specifically, to a method and system for tracking the maximum power point of solar street lamps based on cloud evolution. Background technique [0002] Nowadays, green energy has become an important research topic, and solar energy, which is a representative of green energy, has also attracted widespread attention. With the maturity of solar technology, the application of solar street lamps is becoming more and more extensive. Although as a green energy source, solar street lights can provide people with continuous energy supply, but compared with traditional street lights, the high cost of solar street lights greatly limits its application and promotion. In solar street lights, the cost of manufacturing solar cells often accounts for more than half of the total cost. Therefore, how to improve the unit utilization rate of solar ce...
