摘要(Abstract)：

配电网中光伏、风电等分布式电源(distributed generation,DG)渗透率的不断提高对其充分消纳与高效利用提出了更为严峻的挑战。在此背景下,配电网DG接纳能力问题正受到越来越多的关注,研究DG接纳能力的科学评估方法与提升手段,已成为当前的学术热点之一。首先分析了配电网DG接纳能力的多种限制因素,并分别介绍了接纳能力多维概念模型和基本数学模型,然后从确定性分析和不确定性分析两方面对解析法、智能优化方法和随机场景模拟法3种接纳能力评估方法进行研究综述,并讨论了基于配电网灵活性的分析方法,在此基础上归纳总结了有载调压变压器抽头调整、无功补偿、逆变器功率因数控制等多种DG接纳能力提升技术,最后基于现有研究的不足对未来研究方向进行了展望,旨在为实现DG的充分消纳与高效利用提供借鉴意义,为含高比例DG配电网的规划运行提供科学依据。
