基于分布式光伏接入的配电网消纳能力评估方法研究

Research on Evaluation Method for Consumption Capacity of Distributed Photovoltaic Access to Distribution Network

近年来,分布式光伏并网的容量迅猛增长,多地出现消纳预警,即配电网无法消纳过多的光伏发电。为了配合南方电网公司,以分布式电源“应并尽并、全额消纳”为目标,分析了常见的3种新能源消纳能力评估方法,为供电部门规划人员针对现有的配电网指标参数,快速判断该地区消纳情况提供理论支持。

In recent years,the capacity of distributed photovoltaic grid connection has grown rapidly,and many regions have seen consumption warnings that the distribution grid cannot absorb excessive photovoltaic power generation.In order to cooperate with Southern Power Grid Company and achieve the goal of"integrating and fully consuming distributed power sources",three common evaluation methods for new energy consumption capacity were analyzed,providing theoretical support for power supply department planners to quickly judge the consumption situation in the region based on existing distribution network indicators and parameters.
