北京电网消纳分布式光伏发电能力分析

摘要

随着光伏分布式发电的不断发展，光伏发电出力的随机性、运行方式的复杂性对电网的安全稳定运行带来了极大的挑战。文章在分析分布式光伏发电对系统潮流、电压和网损的基础上，讨论了影响系统消纳光伏发电的主要因素，并详细计算了北京局部电网在不同负荷水平、不同运行方式下，可消纳光伏发电的最大容量。%As the high development of distributed photovolatic power generation, the stability of the grid has the challenge as per the randomness and the sophisticated operation of the distributed photovolatic power. This paper analyzed the affects of distributed photovolatic power to the grid flow,voltage, and net loss, and therefore discussed the main factors with which the grid could mitigate the negative effects from the distributed photovolatic power. The maximum acceptable power capacity from the distributed photovolatic generationin the Beijing local power grid is then calculated with varying load and operation modes.
