Meteorological Issues and Technological Progress in the Development of New Energy Systems
Abstract
[Objective] New energy power generation is expected to continue its development characterized by large scale, high proportion, marketization and high quality in the future. Advancing the energy revolution and accelerating the development of new energy systems are significantly influenced by meteorological issues. [Method] This study analyzed the relationship between key aspects of new energy systems and weather and climate. It highlighted the important role of meteorological work for new energy systems in three fields: support, integration and guarantee. The study presented the development history of wind and solar energy resource assessment technologies in China, covering resource assessment technology, assessment methods for technically available resources and key technical issues for the latest round of wind and solar energy resource censuses. Additionally, it examined the forecast demand and forecast period divisions for wind and solar energy, introduced the technical progress and main products of the China meteorological administration in ultra-short, short, medium, and long-term forecasts, and discussed the implementation of the precise meteorological service demonstration plan for wind and solar power generation (SDP). [Result] Wind and solar energy resource assessment technologies have seen significant improvements; however, they also face challenges posed by large-scale wind turbine generation systems and the diversified utilization of solar energy. Consequently, there is a pressing need to continuously develop new resource assessment technologies to meet the demands of the energy industry. Additionally, enhancing the accuracy of wind and solar energy forecasts requires breakthroughs in methodology. Developing meteorological forecast correction and power prediction models for wind and solar power generation stations, based on the principle of applying a tailored policy to each station, will be a crucial strategy for enhancing forecast accuracy. [Conclusion] Meteorological work should be guided by the Guidelines for High-Quality Meteorology Development (2022-2035) issued by the State Council. It is essential to continually strengthen scientific and technological innovation, as well as social service capabilities, in order to make positive contributions to the high-quality development of new energy systems.
