Abstract

The large-scale application of solar PV in cities has become an important measure to cope with climate change and promote energy transformation. In this research, parametric method and multi criteria decision making (MCDM) are introduced into urban photovoltaic potential assessment to improve the accuracy of urban photovoltaic potential assessment. The constructed combination analysis method supports the key stages in the evaluation process, including land parcel classification, photovoltaic usable area calculation and photovoltaic technology optimization deployment. Xinghualing District, Taiyuan City, Shanxi Province, China was selected as a case study. The solar radiation receiving capacity of the plot is calculated by using the parametric method, and the consideration weight of the the four criteria of photovoltaic power generation is calculated by using the analytic hierarchy process (AHP). The optimal photovoltaic deployment scheme is determined by TOPSIS. The assessment results show that the photovoltaic potential of Xinghualing District is 2790479MWh · a-1, and the land type with the highest power generation potential is multi-storey residential, reaching 635996MWh · a-1. The highest PV potential nuclear density value in the region is located in the southwest area with dense buildings and complex functions. The methods and case studies proposed in this paper take into account the differences of plots within the city and provide theoretical basis and method support for accurate assessment and large-scale utilization of photovoltaic in more urban areas.
