摘要
The clean transformation of the China’s energy structure is related to the establishment of China as an energy power in the new world pattern.The multi-energy systems based on renewable energy,especially solar energy and biomass energy,have become a popular energy supply mode.However,there is no clear theoretical guidance for the quantitative source integration of these two types of clean energy.Concretely,whether the source grades of solar energy and biomass energy are similar in different solar energy modes has not been considered yet.Aiming at this problem,based on the theory of space-time unity of the special theory of relativity,a new principle of source integration is proposed,and the corresponding mathematical model is established.The theoretical calculation of the combination of solar energy and different types of biomass energy is carried out.Under the premise of the similarity between the source grades of different biomass energy and solar energy,the specific solar energy concentration ratio is obtained.According to this principle,the matching efficiency of the multi-energy integration for rice and corn plants can be increased by 39.2%and 36.2%,respectively.
