摘　　要：新能源发电(如风能、太阳能)虽然在电力系统中的占比日益增加,但其在接入电力系统过程中也会对电网稳定性带来影响。本文从多个角度分析新能源并网对电网电能质量的影响,如电压波动、频率偏差、谐波污染等,并提出了相应的保障措施。通过增强电网灵活性、引入先进算法、增加无功补偿等措施,可以有效缓解新能源并网对电网电能质量的影响,确保电网的稳定运行。Although the proportion of new energy generation(such as wind and solar energy)in the power system is increasing,it will also have an impact on the stability of the power grid during its integration into the power system.This article analyzes the impact of new energy grid integration on power grid quality from multiple perspectives,such as voltage fluctuations,frequency deviations,harmonic pollution,etc.,and proposes corresponding safeguard measures.By enhancing the flexibility of the power grid,introducing advanced algorithms,and increasing reactive power compensation,the impact of new energy grid integration on the power quality of the grid can be effectively alleviated,ensuring the stable operation of the grid.
