Description

technical field [0001] The invention belongs to the technical field of micro-grids, and in particular relates to a micro-grid system and a control method thereof. Background technique [0002] The proposal of microgrid aims to realize the flexible and efficient application of distributed power, solve the problem of grid connection of a large number and various forms of distributed power, and the development and extension of microgrid can fully promote the large-scale access of distributed power and renewable energy It is an effective way to realize the active distribution network and make the transition from the traditional power grid to the smart grid. Nowadays, most of the micro-grid systems use wind energy and light energy to generate electricity. However, most of the photovoltaic power generation panels and wind energy generators are fixed installations, which can only capture light energy or wind energy in one direction. Different, and the angle of the sun’s irradiatio...

Problems solved by technology

Nowadays, most of the micro-grid systems use wind energy and light energy to generate electricity. However, most of the photovoltaic power generation panels and wind energy generators are fixed installations, which can only capture light energy or wind energy in one direction. Different, and the angle of the sun’s irradiation on the earth in winter and summer will also be biased. The angle of the photovoltaic power generation panel is fixed, which will cause waste of light energy and cannot improve the power generation efficiency of the photovoltaic power generation panel. The wind direction is even more changeable. The same direction will also affect the power generation effect
