区域光伏发电出力特性分析研究
摘要:为进一步分析区域光伏发电带来的消纳问题,以甘肃省典型光伏电站实际出力数据为分析样本,研究了区域光伏发电的出力特性。考虑单个光伏电站出力特性,分析了光伏日间出力的季节特性和天气特性。考虑光伏发电出力的集群特性,分析了不同光伏电站之间的波动性、相关性和同时率。研究结果表明:甘肃省总体光伏出力水平较高,但存在一定的地域差异;日间出力具有周期性,波动存在随机性;区域光伏电站间出力具有相关性;区域光伏电站出力相对于单个光伏电站出力的同时率有所降低,并网时对电网的影响降低,可改善“弃光现象”的发生。所提出的光伏发电出力特性量化分析指标为区域光伏发电消纳分析提供了思路及方法,为光伏发电发展规划的制定提供了参考依据。
Abstract:In order to further analyze the consumption problem caused by regional photovoltaic power generation, the actual output data of typical photovoltaic power plants in Gansu province was used as an analysis sample to study the output characteristics of regional photovoltaic power generation. The output characteristics of a single photovoltaic power station was considered, and the seasonal and weather characteristics of photovoltaic daytime output was analyzed. Considering the cluster characteristics of photovoltaic power generation output, the volatility, correlation and simultaneity rate among different photovoltaic power plants were analyzed. The research results show that the overall photovoltaic output level in Gansu province is relatively high, but there are certain regional differences. Daily output is cyclical, while fluctuations are random. The output of regional photovoltaic power plants is correlated. Compared with the output of a single photovoltaic power station, the output of regional photovoltaic power plants has been reduced at the same time, and the impact on the grid when connected to the grid is reduced, which can improve the occurrence of “photovoltaic abandonment phenomenon”. The proposed quantitative analysis index for photovoltaic power generation output characteristics provides ideas and methods for regional photovoltaic power consumption analysis, and provides a reference for the formulation of photovoltaic power generation development plans.
