Complementary and advantages of wind solar hybrid power generation system

Wind energy and solar energy are important renewable energy with clean and abundant reserves. Due to the influence of seasonal change and weather change, wind energy and solar energy are unstable and discontinuous energy. There are defects of unstable power generation in separate wind power generation or solar photovoltaic power generation. However, wind energy and solar energy have natural complementary advantages, that is, the solar light intensity during the day and more wind at night; In summer, the sunshine is good and the wind is weak, while in winter and spring, the wind is strong and the sunshine is weak. Wind solar complementary power generation system makes full use of the complementary of wind and solar energy resources. It is a new energy power generation system with high cost performance.

Wind and solar energy can independently form a power generation system or a hybrid power generation system of wind and solar energy, that is, wind solar complementary power generation system. The form of power generation mainly depends on the local natural resource conditions and the comprehensive cost of power generation. Wind power generation should be used in areas with good wind energy resources, and solar photovoltaic power generation can be used in areas with abundant sunshine. Generally, The comprehensive cost of wind power generation is far lower than that of solar photovoltaic power generation. Therefore, wind power generation system should be preferred in areas with good wind energy resources. In recent years, wind solar complementary power generation system has been more and more widely used because of its resource complementary, power supply security and stability, which are better than single energy power generation system, and the price is in the middle.

Wind power generation has the problem of no power generation when there is no wind (especially in summer, the day is long and the night is short, and the solar intensity season). Solar photovoltaic power generation also has the problem of no power generation when there is no sun (especially in winter, the day is short and the night is long, and the north wind is strong). If wind power generation and solar photovoltaic power generation are reasonably combined, 365 days of continuous power generation can be realized.
