摘要：
As a fundamental energy consumption base in China, the Beijing-Tianjin-Hebei (BTH) region has experienced an increasing demand for clean energy in recent years. Photovoltaic power generation is a key for accelerating the transformation of energy infrastructure in China and achieving the goal of carbon neutrality during the 14th Five-Year Plan period (2021-2025). Taking the BTH region as a study area, we construct a comprehensive evaluation index system of "terrain-weather-cost" to calculate a photovoltaic development suitability index. We subsequently analyze the spatial pattern characteristics of photovoltaic development suitability in the study area in 2018 and quantitatively examine power generation potential and emission reduction effect under different scenarios of photovoltaic development suitability. Results indicate that: (1) The suitable areas for photovoltaic development account for 22% of the total area of this region, and the largest portion of this area is moderately suitable for photovoltaic development. The "Yanshan-Taihang mountains" line geographically divides the areas that are suitable and unsuitable for photovoltaic development, and a range of potential areas are distributed in prefecture-level cities of Chengde, Zhangjiakou and Baoding. (2) Photovoltaic power generation in the BTH region has great potential. Specifically, the annual power generation potential of the extremely and highly suitable areas is about three times more than the total power consumption in the same year of 2018. (3) The energy-saving and emission reduction effects of photovoltaic power generation are remarkable. If the extremely and highly suitable areas are used for photovoltaic development, there will be an approximate 47% reduction in carbon emissions across the whole region, according to the data of 2018. (4) Despite being restricted by limited land resources and the absence of an advanced transmission network or energy storage system, large-scale photovoltaic development is still a viable solution to energy supply issues. It still improves energy infrastructure, achieves the goal of carbon neutrality, and enhances the well-being of citizens in the context of global climate change and the new low-carbon economy. © 2022, Science Press.
