Research on Macroscopic Site Selection Scheme for Photovoltaic Power Stations Based on GIS Technology:Take Siziwang Banner as An Example
In order to achieve peak carbon dioxide emissions before 2030 and achieve carbon neutrality by 2060,the site selection of photovoltaic power stations is of great importance.This paper proposed a large-scale macroscopic site selection scheme based on GIS technology.By analyzing the effects of radiation conditions,latitude and longitude,topographic factors and environmental sensitive areas on the photovoltaic power station,it was found that the average annual total horizontal radiation irradiation of Siziwang Banner was 1621.6 kWh·m-2,and the average annual total radiation irradiation of the optimal slope plane was 2239.4 kWh·m-2.According to the classification of solar energy resource,Siziwang Banner belonged to the B-level"very rich"area.The southern and southwestern regions of Siziwang Banner should be developed first.At the same time,considering the flexible and diverse characteristics of photovoltaic power generation,distributed photovoltaics could also be developed in the central and eastern regions of Siziwang Banner to make full use of resource advantages.
