Research on the framework of planning model for the photovoltaic generation integration in China

The integration of photovoltaic generation into the power grid is one of the most significant measures for the guarantee of national energy security, the construction of low-carbon society and the enforcement of National Twelfth Five Years Plan in China. Based on the in-depth surveys, this paper presents the framework of the infrastructure construction planning of photovoltaic generation from the perspectives of the layout planning of corresponding facilities needed for the integration, and construction planning evaluation. The former, which is based on the energy location information (ELI), as well as the positional weight information (PWI), is adopted to evaluate the impacts of connection spot for the power grid's security, which contains a new methodology to evaluate the availability of solar energy by introducing the concepts of solar resource unavailability frequency (SRUF) and solar resource average unavailability duration (SRAUD); the latter proposes a evaluation system including modules of economic analysis and environmental analysis by using AHP with group decision making and information entropy. The findings of this research provide basic theoretical references for the planning of photovoltaic generation integration in China.
