摘要

由于传统化石资源的紧缺,光伏发电等可再生分布式发电发展迅速。考虑到这种情况,分析光伏发电带来的影响具有重要意义。考虑光伏发电出力的波动,对分布式电力系统状态的多个指标进行了分析。首先分析了光伏发电对基频电压和谐波畸变的多重影响机理。然后提出了考虑光伏发电出力波动的电力系统状态分析结构。最后对修订后的IEEE 33总线系统在不同场景下进行了分析。得到了一天内的基谐波状态的统计特征,以反映光伏发电带来的影响。

Analysis of the Impact of the Photovoltaic Generation on Distributed Networks Considering the Fluctuation of Its Output
Due to the shortage of traditional fossil resources, the renewable distributed generation like photovoltaic (PV) generation grows fast. Considering this situation, analyzing impact brought by PV generation is of great significance. This paper analyzes multiple indicators of the distributed power system state considering the fluctuation of the PV generation's output. The mechanism of the multiple impact of PV generation on fundamental voltage and harmonic distortion is analyzed first. Then the power system state analyzing structure considering the fluctuation of output of PV generation is proposed. At last the analyzing process is conducted on the revised IEEE 33 bus system in different scenarios. Statistical feature of the fundamental and harmonic state in one day is obtained to reflect the influence brought by PV generation.
