摘要 随着人们的生活水平不断提高,分布式发电已成为国际公认的能源生产利用方式。光伏项目可最大限度地利用太阳能可再生能源,取代煤炭和石油等传统能源,并有效促进绿色和低碳发展。光伏发电易受温度和光强等环境因素的影响,全天温度变化和光强变化可能导致不稳定和第二输出功率,以及电压波动等能源质量问题,同时并网光伏发电是一种通过电子功率器件实现的交流直流逆变,电力机组高频切换过程必然会产生大量谐波。 The continuous development of science and technology and the rapid development of social economy have led to the tremendous development of people’s daily life and production,and people’s living standards have been continuously improved.Distributed power generation has become an internationally recognized way of energy production and utilization.Photovoltaic projects can maximize the use of solar renewable energy,replace traditional energy sources such as coal and oil,and effectively promote green and low-carbon development.Photovoltaic power generation is easily affected by environmental factors such as temperature and light intensity.Changes in temperature and light intensity throughout the day may cause instability and second output power,as well as energy quality problems such as voltage fluctuations.At the same time,grid-connected photovoltaic power generation is a kind of AC and DC inverters realized by electronic power devices will inevitably generate a large number of harmonics during the high-frequency switching process of power units.
