中文摘要:
      伏发电近几年得到快速发展,其出力特性的分析研究逐步深入,但还没有形成成熟的光伏出力评价指标体系。针对这个问题,提出了面向电网运行的光伏出力特性指标体系。通过理论研究和数据测算,发现光伏出力的波动性较风电明显要小、规律性较强,完全可以采用简单、精炼的指标体系来表述。提出采用指标“季节属性”来表征光伏发电在不同季节的可出力时段,指标“平均出力”来表征光伏全天出力整体水平,指标“全日最大出力”来表征光伏出力对系统调节能力的影响。以某实际光伏电站出力为例,分析了所提评价体系的具体指标和分类结果。计算结果说明了通过核心指标体系,可以直观描述光伏出力特性,并有助于形成典型出力曲线,具有很好的应用前景。
英文摘要:
      There has been a rapid development of photovoltaic (PV) power in recent years.Further analysis about the feature of PV power output was also a research focus.However, we have not got the mature PV power evaluation index system.After the data calculation, we found that the randomness of PV power output was less than that of wind power output.Therefore, we could choose alternatively some simple and refined index system to character PV power output.In this paper, we proposed an evaluation index system for PV power output.The index ‘PV power output season’ is used to describe the period of PV power output during different season.The index “averaged PV power output” is used to describe the level of PV power output.The index “maximum PV power output per day” is applied to quantitatively analyze the impact of PV power output on peaking service.The paper takes the output of an actual photovoltaic power station as an example, explains the indexes in detail and the application in curve classification.The results show that the proposed index system can directly describe PV power characteristics and form the typical curves, which has good application prospect.
