Risk Assessment on Photovoltaic Power Generation Project by Grey Correlation Analysis and TOPSIS Method
Zhijie Wang · Power System Technology · 2013
Due to long construction cycle,massive investment and many involved aspects of photovoltaic(PV) power generation,various uncertain factors and environmental factors,which both PV generation project and project manager have to be faced with,sharply increase and various risks going with the item appear,so it is of great significance to perform effective risk assessment on PV generation project.According to typical features of PV generation project,a more comprehensive risk assessment index system is proposed,in which the grey correlation analysis and technique for order preference by similarity to ideal solution(TOPSIS) method is utilized to construct a grey ideal value approximation model,to assess the risks in PV generation project.Using the proposed risk assessment index system,results of empirical research on eight PV generation projects that will be constructed in a certain province in Northwest China show that using the proposed method the overall evaluation on alternate schemes can be implemented and the differences between alternate schemes,in which the variation tendency of internal factors of alternate schemes and the ideal scheme can be reflected, therefore the proposed risk assessment method is effective.
