大容量分布式光伏并网对配电网综合影响分析
Integrated Impact of Large-capacity Distributed Photovoltaic on Power Grid
摘要
Abstract
To study the integrated impact of large capacity distributed photovoltaic(PV)on the distribution network, the models on DIgSILENT platform are constructed based on the data of a practical grid-connected distributed PV proj⁃ect in Guangdong Province. The simulation is conducted from the perspective of load flow,short circuit,three-phase un⁃balanced degree,harmonic and voltage fluctuation at the points of common coupling(PCC)to compare the performances of distribution network before and after PV connection. The results show that in response to the increasing scale of dis⁃tributed PV connected to the distribution network,the grid-connection tests and installed capacity control of distributed PV should be strengthened to restrict the problems of light load and inverse active power of transmission lines ,low pow⁃er factor at PCC,short-circuit current enlargement and deteriorating power quality within allowable extent.关键词
