Standardized modeling for photovoltaic generation system based on parameter identification method

摘要

Photovoltaic power generation is a typical form of distributed generation. Standardized modelling approach for photovoltaic generation system based on parameter identification method is presented in this paper. Detailed simulation modelling methods and models of photovoltaic generation system are introduced, and based on principles of the least squares method, a detailed parameter identification mode is established in the software DlgSILENT. According to the actual structure and parameters, photovoltaic generation station model is created. Comparison of simulation results and actual operation data is presented, which verifies the validity of standardized modelling method. And the universality for the identification parameter method is analyzed, while universal conclusions are presented.
