摘要/Abstract

摘要： 随着分布式光伏大量接入，配电网电能质量、短路容量、潮流分布等都受到一定的影响，光伏发电在就地消纳的同时可能产生倒送，因此传统配电网面临升级改造的新形势。对于不同典型功能区的光伏发电接入，如何定量分析配电网建设改造工作量是一个亟待解决的问题。根据光伏最大盈余发用比指标，对不同类型功能区负荷密度与发电功率密度进行对比研究，分析不同类型功能区光伏消纳及配电网改造情况，研究分布式光伏接入对配电网建设改造影响，提出不同光伏最大盈余发用比下配电网工程改造及投资规模建议，为实现配电网接纳分布式光伏改造提供指导和建议。

Abstract: With a large number of distributed photovoltaic devices connected to the grid, electric energy quality, short circuit capacity and power flow of distribution networks are all impacted more or less. Excess photovoltaic power that cannot be consumed locally will be transmitted back to the grid. So the traditional distribution networks are facing new challenges of reconstruction and upgrading. For distributed PV accessing into different functional areas, the issues are becoming more urgent about how to quantitatively analyze the constructions of distribution networks. In this paper, according to the new guideline of absorption capacity of distributed PV, load density and generation power density in typical functional zones are analyzed and comparison research is accomplished. Effects of distributed PV connected to grid on distribution network constructions in typical functional zones is investigated and suggestions of distribution constructions is proposed under different scenarios, which will provide guidance and advice for distribution network reconfiguration for the absorption of more distributed PV power.

Key words: typically functional areas, distributed photovoltaic power, distribution network construction and reforming, ability of PV absorption
