摘要
分布式光伏并网系统能够分散发电,减轻了传统集中式发电厂的负担,降低了电网输电压力,有利于提高电网的功率因数,改善电网的负荷特性,进而提升电网的稳定性和可靠性.分布式光伏并网系统的发展在一定程度上促进了电网技术的升级和转型,但是由于光伏发电的不确定性和间歇性特点,分布式光伏并网系统接入后可能影响电网的电压、频率等参数.通过研究分布式光伏并网对电网运行的影响,采取适当的配网技术和控制手段来应对这些挑战,保障电能质量和电网的安全稳定运行.
Abstract
Distributed photovoltaic grid-connected system can disperse power generation,reduce the burden of traditional centralized power plants,reduce the transmission pressure of power grid,improve the power factor of power grid,improve the load characteristics of power grid,and then improve the stability and reliability of power grid.The development of distributed photovoltaic grid-connected system has promoted the upgrading and transformation of grid technology to a certain extent.However,due to the uncertainty and intermittent characteristics of photovoltaic power generation,the grid voltage,frequency and other parameters may be affected after the distributed photovoltaic grid-connected system is connected.By studying the influence of distributed photovoltaic grid connection on power grid operation,appropriate distribution technology and control means are adopted to meet these challenges,ensuring power quality and safe and stable operation of power grid.
