Abstract
To address the issues of insufficient refinement of marine use standards for offshore photovoltaic(PV)projects and the need to improve the efficiency of marine resource utilization,this study conducts research from four dimensions:policy review,technical calculation,case verification,and optimization recommendations.A review of national and local policies reveals that the marine use policy for offshore PV issued by the Ministry of Natural Resources in 2024 clarifies marine use area control indicators based on photovoltaic power generation efficiency and latitude differences.However,existing policies still lack detailed consideration of core factors such as differences in regional development models,and the dynamic quantitative indicator system remains incomplete.This study establishes a calculation model based on the principle of intensive and economical use.Taking"power generation efficiency and latitude differences"as the basic premise,it further derives correction coefficients for variables such as development models on marine use standards,and proposes regional marine use control indicator values of 1.119～1.492 hectares/MW for 9 coastal provinces(municipalities)in China.Verification using 60 planned offshore PV projects in Jiangsu Province from 2025 to 2030 shows that under conventional development scenarios,after accounting for constraints related to ecological protection and functional avoidance,the deviation between the planned values and calculated values is≤5%.Finally,recommendations for intensive marine use are put forward from three aspects:spatial optimization,indicator management,and technological upgrading.This research provides a reference for the standardized management of marine use in offshore PV projects and the efficient utilization of marine resources.关键词
