光伏发电在配电系统的渗透引起的电网不平衡研究

Research on Grid Imbalance Caused by the Penetration of Photovoltaic Power Generation in Distribution Systems

分析了光伏渗透率对电网影响,对配电系统中影响电压波动的最明显因素进行模拟,以分析不同光伏渗透水平下问题的严重性,通过仿真分析,随着光伏渗透率的增加,所需的变压器抽头转换次数增加,导致变压器的使用寿命缩短,因此通过调节措施将电压调节在标准允许的范围内。

This article analyzes the impact of photovoltaic penetration rate on the power grid and simulates the most obvious factors affecting voltage fluctuations in the distribution system to analyze the severity of the problem under different levels of photovoltaic penetration.Through simulation analysis,it can be concluded that as the photovoltaic penetration rate increases,the required number of transformer tap conversions increases,leading to a shortened service life of transformers.Therefore,by adjusting measures,the voltage is adjusted within the allowable range of the standard.
