He previously presided over a graduate research innovation project funded by Jiangsu Province. Currently, he serves as Secretary of the Young Geographers Working Group of the Asian Geographical Association and has been invited to review for journals such as Information Geography and Springer Nature Computer Science.
Report Abstract:
Distributed photovoltaic systems, known for their flexible deployment, low carbon emissions, and high efficiency, are gradually becoming a key pillar in the transition of urban energy structures. Urban environments contain abundant spatial resources suitable for photovoltaic installations, such as building rooftops, facades, and roadside noise barriers. However, accurately identifying their potential for photovoltaic and assessing economic feasibility remain significant challenges.
This report focuses on assessing the photovoltaic potential of urban-scale buildings and transportation infrastructures, introducing systematically key processes including spatial modeling of solar radiation, building shadow simulation, and photovoltaic potential estimation. The talk further explores the development potential and application models of photovoltaic in typical urban spaces, providing technical support and decision-making references for low-carbon urban energy planning.
