Description

technical field [0001] The invention relates to the field of renewable energy power generation, in particular to an outdoor energy storage wind-solar complementary off-grid power generation system. Background technique [0002] Human production and living energy currently mainly rely on fossil energy, including oil, natural gas, coal and other naturally formed, non-renewable resources. Human beings are facing the crisis of fossil energy depletion, and energy shortage is one of the problems that human beings need to solve urgently. Therefore, countries all over the world are vigorously developing renewable energy. Among them, solar energy and wind energy have strong complementarity in terms of time and area, mainly manifested in the strong sunlight intensity and low wind during the day, and weak light intensity at night, but the wind energy is strengthened due to the large surface temperature difference. In summer the sun is strong and the wind is low; in winter the sun is ...
