Abstract

The invention relates to the technical field of photovoltaic power generation, in particular to an intelligent photovoltaic power generation device and a control method thereof. According to the invention, photovoltaic power generation and the hydrogen fuel cell are effectively combined together; an electrolyzed water triggering mechanism is adopted, and an electrolytic tank, a hydrogen energy storage device, an oxygen energy storage device, a hydrogen inlet, an oxygen inlet and a hydrogen fuel cell are subjected to electrochemical reaction to generate electric energy; and the maximum power point tracking principle is used, the photovoltaic array output voltage and current are tracked, the duty ratio is adjusted for impedance matching, meanwhile, the photovoltaic array is always in the maximum illumination state by calculating the optimal illumination direction, the photovoltaic power generation electric energy conversion efficiency is improved, furthermore, weather data in cloud service can be obtained through an Internet of Things platform, and the mobile phone APP can remotely monitor the electric energy data of the system and control the steering of the photovoltaic cell array.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to an intelligent photovoltaic power generation device and a control method thereof. Background technique [0002] In the past few decades, my country's economy has developed rapidly, especially the development of the coal and steel industries is very mature, but due to the continuous mining of raw coal, oil, natural gas, etc., my country's non-renewable energy has decreased sharply and the ecological environment has been destroyed. Therefore, the development of green Renewable energy is a necessary measure to ensure the sustainable development of human beings. The most abundant source of electrical energy in nature is solar energy, and my country is vast and rich in sunlight resources. According to statistics, the average total solar radiation across the country is about 4KWh / m 2 , even up to 6KWh / m in Tibet 2 . Combined with my country's geographical advant...
