摘要

分布式电源接入对配电网电压的影响是目前分布式电源接入最重要的课题之一。为适应未来分布式电源快速发展的接入需求

从现实情况出发

研究了分布式电源接入配电网时的影响因素

分析了分布式电源自身功率因数调节、无功补偿、储能装置等辅助措施对分布式电源最大允许接入容量的影响。计算结果表明

分布式电源自身功率因数调节有助于提高分布式电源允许接入容量

但效果不明显;采用无功补偿装置和储能装置可较大幅度提高分布式电源允许接入容量

是未来适应分布式电源发展的有效措施。

Abstract

The impact of distributed power access on the voltage of the distribution network is one of the most important issues for distributed power access. In order to adapt to the access requirements of the rapid development of distributed power sources in the future

this paper studies the influencing factors when distributed power sources are connected to the distribution network based on the actual situation. The influence of auxiliary measures such as distributed power supply′s own power factor adjustment

reactive power compensation

and energy storage device on the maximum allowable access capacity of distributed power sources is analyzed. The calculation results show that the power factor adjustment of distributed power sources can help to increase the allowable access capacity of distributed power sources

but the effect is not obvious. Reactive power compensation devices and energy storage devices can greatly increase the allowable access capacity of distributed power sources. This is an effective measure for future development of distributed power sources.
