摘要
针对太阳能储热系统容量配置进行设计优化。对相同地区建设的同规模太阳能光热电站,在储热时间从0变化至8h的情况下,分析此光热电站的SCA回路、年发电量、占地面积、镜场投资、支架系统投资、土地费用、储能系统投资、差额内部收益率、增量回收期等变化趋势,选择储热系统的最佳占比。通过此研究,确定合适的容量配置,可以降低太阳能弃光率,提高太阳能发电有效性及年利用率,使项目达到经济性最优。
This paper makes an optimal design of the capacity configuration for solar thermal storage system.As for the solar thermal power plants of the similiar scale and in the same area,with the thermal storage time varying from 0to 8h,it analyzes the change trend of the power plants in terms of SCA circuits,annual power generating capacity,occupied area,field investment,support system investment,land cost,energy storage system investment,balance internal rate of return,incremental payback period.The best proportion of thermal storage system is selected.This research can help to determine the appropriate capacity configuration,reduce the solar light discard rate,improve the efficiency of solar power and annual utilization,and optimize the project economically.
