摘要

针对位置和容量不合理的分布式电源(Distributed generation，DG)会对配电网的网损、电压稳定性及可靠性等方面带来不利影响，导致风能、太阳能等分布式能源非充分利用的问题。以实测的风力发电机出力数据为支撑，采用配电网柔性交流输电系统(distributed flexible AC transmission system，DFACTS)对配电网潮流进行优化减少对DG位置和容量限制的方法，仿真模拟不同时刻风力发电机出力和负荷的双重变化，并对系统的网损、电压水平和可靠性进行分析，经IEEE36配电系统验证表明：在大量投运DG的配电网上加装DFACTS设备起到降低网损、稳定系统电压和提高可靠性的作用。

Abstract

:Distributed generation (DG) with undesirable location and capacity has adverse impacts on transmission losses of the distribution network，voltage stability and network reliability，which could not make full use of the renewable energy sources．In this paper

the distribution network is optimized by using distributed flexible transmission system (DFACTS)

which reduces the limitation of DG position and capacity. Based on the measured data of the wind power generator

the Monte Carlo simulation is used to simulate the change of the output and load of the wind power generator at different times

and the line losses

voltage level and reliability are analyzed. Finally

the use of IEEE36 power distribution system verification shows that DFACTS equipment installed on a large number of DG distribution network can reduce the line losses

stabilize the system voltage and improve the reliability.
