中文摘要：

随着新能源的不断开发和利用,太阳电池作为一种新型绿色能源,越来越受到电力行业的青睐。在大范围研究光伏作为分布式电源接入配网当中,电能质量无疑成为衡量其利用价值需考虑的一个重要因素。在电能质量的考虑因素中,电子电力控制元件引起的谐波注入电网并对其影响和电压的波动和闪变,还有电压稳定性,逐渐成为最重要的参考标准之一。对世界光伏发展和趋势做了一定的调研,也对我国大力发展光伏技术做了一定的调查,在考虑减少谐波含量,保证电压稳定性中提出了不同的控制策略。

英文摘要：

With the continuous development and utilization of new energy sources, solar battery as a new type of green energy is in favor of more and more electric power industry. In the research of photovoltaic large-scale as distributed power distribution networks, no doubt the power quality has become a measure of its utilization is an important factor in value consideration. In consideration of power quality, harmonic components caused by the electronic power control into power grid and the influence and the voltage fluctuation and flicker, and voltage stability,has become one of the most important reference standard. Some research on the world＇s photovoltaic development and trend was done, and also the development of photovoltaic technology to China was investigated. In order to reduce the harmonic content and ensure the voltage stability, a lot of control strategies were proposed.
