Recently, the "Mesoscale Numerical Simulation Method for Climate Effect Assessment of Onshore Centralized Photovoltaic Power Stations" jointly developed by the National Climate Center, Tsinghua University, and the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences has won a national invention patent.

The research team established a numerical simulation method for the climate effect of photovoltaic power plants based on the numerical parameterization and sensitivity numerical tests of the surface radiation balance, heat balance and surface drag damping effect of photovoltaic power plants, which solved the objective and quantitative evaluation of the climate impact of large photovoltaic power plants, and The numerical simulation method uses explicit and complete technical methods to numerically parameterize the core physical processes of photovoltaic power plants such as short-wave radiation balance, sensible heat heating, and surface dynamic drag, which effectively reduces the model's high dependence on the background climate characteristics of the location of the photovoltaic power plant. , with strong universality.

Chang Rui, a senior engineer at the National Climate Center, said that at present, the research on climate effects of large-scale photovoltaic power station development is limited to individual case fixed-point observations, theoretical calculations or extensive simulations, and it is impossible to adapt to changes in the climate of photovoltaic power station development and the future development planning of the photovoltaic industry. Provide effective support. In response to this problem, the research team adopted this numerical simulation technology, which can not only post-evaluate the climate effect of the existing photovoltaic power station, but also conduct a pre-evaluation of the climate effect of the proposed photovoltaic power station, so as to provide information for the site selection and construction of climate-friendly power stations. scientific basis.
