Problems solved by technology
[0003] Due to the great uncertainty of scene changes during the movement of vehicles, and the surrounding environment has various influencing factors, such as leaf shading, dust, high temperature, etc., it is often difficult for movable solar panels to receive sunlight for a sufficient time and Will be disturbed and damaged by the environment
Therefore, the output voltage of the solar panel will always fluctuate greatly on the way, which not only causes the output power of the photovoltaic inverter to be unstable, but also easily damages the components of the inverter

Embodiment Construction
[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0047] figure 1 It is a structural diagram of a distributed photovoltaic inverter intelligent control method of the present invention. like figure 1 As shown, a method and device for intelligent control of a distributed photovoltaic inverter in this embodiment may specifically include:
[0048] According to the season, weather and day and night to judge whether to open the distributed movable photovoltaic power generation panel. The power generation efficiency of photovoltaic panels is mainly determined by the intensity of sunlight and temperature. The intensity of the sun's rays depends on the season, weather, and day and night changes. If the temperature of photovoltaic panels is too high or too low, the power generated will be significan...

The invention provides an intelligent control method and system for a distributed movable photovoltaic inverter, and the method comprises the steps: judging the weather change and sunlight intensity in a moving process according to seasons, weather and day and night, determining whether to start a distributed movable photovoltaic panel or not, and enabling the photovoltaic inverter to obtain a maximum power point through a perturbation and observation method when the photovoltaic panel is started; training the sunshine site prediction model through a deep learning framework, and predicting the light change on the driving route according to the electronic map; the illumination distribution, the illumination angle change and the temperature change of the photovoltaic panel are detected in real time, the angle of the distributed movable photovoltaic panel is adjusted, and an incremental conductance method is adopted to enable the photovoltaic inverter to obtain the maximum power point; and adjusting the efficiency of the photovoltaic inverter according to the generated power of the photovoltaic panel, changing the maximum power point tracking algorithm, and overhauling the photovoltaic inverter according to the environmental data. According to the invention, the distributed movable photovoltaic inverter and the acquisition rod can become more intelligent in the operation process.
Description
【Technical field】 [0001] The present invention relates to the technical field of intelligent equipment, in particular to a method and device for intelligent control of distributed photovoltaic inverters. 【Background technique】 [0002] Since the 21st century, the demand for energy in human society has continued to increase. At the same time, factors such as high energy demand, environmental protection, and renewable energy have promoted the status quo of energy utilization from being dominated by petrochemical energy to gradually changing to a diversified combination of renewable green energy. advanced situation. Among them, solar energy is the source of the earth's energy, and it is the most widely distributed and resource-rich renewable energy on the earth. Therefore, the solar energy industry has developed rapidly in recent years, and photovoltaic power generation technology is widely used in various scenarios of social life. Among them, the application of mobile photovo...
