摘要
为研究分布式光伏并网对网供负荷的影响,首先分析了光伏本身出力特性,其次分析了分布式光伏对网供最大负荷、最大负荷出现时刻、网供峰谷差的影响以及不同天气情况下对网供负荷的影响等,并通过对大量数据的规律性挖掘,最后给出了分布式光伏对网供负荷的影响规律,为分布式光伏影响下的网供负荷特性变化研究奠定了理论基础。
In order to study the influence of distributed photovoltaic on network supply load,this paper analyzed the output characteristics of photovoltaic itself and then analyzed the influence of distributed photovoltaic on multiple angles of the maximum load,the maximum load time and the peak-to-valley difference of the network and the influence on network load under different weather conditions.In the end,this paper pointed out the influence regularities of distributed photovoltaic on the load of the net,laying a good theoretical foundation for the study of the change of network load characteristics under the influence of distributed photovoltaic.
