RESEARCH ON GRID CONNECTION METHOD OF AVERAGE PV POWER GENERATION CAPACITY BASED ON 24 SOLAR TERMS
摘要
Abstract
In response to the impact of grid connection of PV power generation on the stability of the power grid,this paper analyzes the power generation of the PV power generation system in segments based on the 24 solar terms,proposes the idea of average grid connection of PV power generation,and improves the unstable situation of the power grid caused by frequent grid connection of PV power generation.Firstly,taking Hebei region as an example,the PV power generation in Hebei region is simulated based on meteorological data combined with System Advisor Model(SAM)software.Then,it is segmented into 24 solar terms and the correlation between PV power generation and 24 solar terms is analyzed.Then,based on this,various regions of China are selected as research objects to verify the correlation between PV power generation capacity in each region of China and the 24 solar terms.A grid connection method based on the average PV power generation capacity of the 24 solar terms is proposed,and the stability of the power grid is compared between the proposed method and the real-time grid connection method.Finally,taking a household grid connected PV power generation system in Hebei region as an example,the stability improvement of the power grid is verified when using the average PV power generation capacity based on 24 solar terms for grid connection.The research results indicate that there is a significant correlation between PV power generation capacity and solar terms in most regions of China.After adopting the average grid connection method based on 24 solar terms,the impact of PV power generation on the grid can be effectively reduced during grid connection.关键词
