摘要
西藏地处高原高寒地区,太阳能资源极其丰富,建设光储电站有利于改善当地电源结构。然而,高原高寒的恶劣环境对光储设备影响较大。通过对西藏电网结构和日喀则市太阳能资源进行分析,评估建设光储电站的可行性;以朗明桑珠孜50 MW并网光储电站为例,提出适用于高原高寒地区的光储电站设计方案;以光储电站日弃电量最小为目标,进行储能容量配置;并结合光储电站运行数据对电站设计方案进行验证分析。研究表明:光储电站的设计方案在高原高寒地区具有适用性,50 MW光伏发电系统配置12.5 MW/100 MW·h电池储能较为合理,单日可减少约60 MW·h弃电量。研究结果可为高原高寒地区并网光储电站的设计提供参考。
Tibet is located in a frigid plateau region,and its solar energy resources are extremely rich.Photovoltaic energy storage power stations are conducive to improving the local power structure.However,the severe environment of the frigid plateau region has a significant influence on photovoltaic energy storage equipment.The structure of the Tibet power grid and solar energy resources in Shigatse were analyzed in this paper,and the feasibility of building photovoltaic energy storage power stations was evaluated.Taking Langming Sangzhuzi 50 MW grid-connected photovoltaic energy storage power station as an example,the paper proposed the design scheme of photovoltaic energy storage power stations suitable for frigid plateau regions.The energy storage capacity was set with the objective of minimizing the curtailment of the photovoltaic energy storage power station.The design scheme was verified by the operation data of the power station.The results showed that the scheme is applicable in frigid plateau regions,and an energy storage system with a capacity of 12.5 MW/100 MW·h matches the 50 MW photovoltaic system well,which can reduce about 60 MW·h abandoned power per day.The research can provide guidance for the optimization design of gridconnected photovoltaic energy storage power stations in frigid plateau regions.
