Abstract:
To support the goal of "peak CO2 emissions and carbon neutrality", China's new energy sources, mainly wind power and photovoltaic power generation, will continue to see accelerated development in the longer term. In the process of rapid development of wind power and solar power generation, environmental factors bring challenges that affect the safe operation of the systems while creating high operation and maintenance costs. This paper reviewed the lightning strike, icing, dust accumulation, encapsulation and intelligent operation and maintenance of power generation systems, summarized the research progress in China and abroad, and clarified five key issues to be solved as follows: lightning strike mechanism of rotating wind turbines under the influence of multiple climate factors, development of all-weather wind turbine blades adapting to complex environments, reliable encapsulation technology of perovskite solar cells with water and oxygen isolation, digital-twin based all-weather intelligent operation, and maintenance technology of wind power and solar generation equipment and zero CO2 emission recyclable technology of wind power and solar generation equipment. The effective solution of these problems will enhance the adaptability of wind power and solar generation system in complex environment, promote the safe operation of the new energy generation system, reduce the dependence on fossil energy with high CO2 emission, and contribute to achieving the goal of "peak CO2 emissions and carbon neutrality".
