“双碳”背景下，光伏装机容量持续增加但建设用地却不断减少，促使渔光互补等复合型光伏发电项目在“十四五”期间成为开发建设的热点。如何合理评估渔光互补光伏发电项目的技术经济特性，为项目开发建设提供决策依据有待进一步研究。以广东省某150 MWp渔光互补集中式光伏发电项目为研究对象，通过优化容配比、组件倾角及阵列间距等边界条件制定最佳建设方案。以此为基础，利用通用LCOE模型测算项目平准化度电成本，分析发电量、单位造价、贷款利率、运维成本等不确定性因素对项目LCOE的影响程度，考察该项目的可行性。经评估，该项目技术可行、经济合理、风险可控，具备一定开发价值。

Under the background of “carbon peaking and carbon neutrality”,the installed capacity of PV power system continues to increase but the construction area decreases correspondingly so that fishery-PV complementary power generation project becomes a hot spot of investment during the period of “14th five-year plan”.It’s required to further study how to evaluate the technical and economic characteristics of fishery-PV complementary power generation project so as to provide a support for decision making when this kind of project is developed.A 150 MWp fishery-PV complementary power generation project was investigated as research object.The capacity ratio,tilting angle and array spacing as boundary condition were optimized to find an optimum scheme.Based on this optimum scheme,the levelized cost of electricity (LCOE) was calculated with a generic model.Moreover,these uncertainty factors including annual electricity output,cost per kilowatt,loan interest rate and operational & maintenance cost were analyzed to figure out their influences on LCOE so as to investigate the feasibility of this project.It has been proven that this project is valuable to be developed based on its technical feasibility,economic reasonability and risk controllability.
