摘要

本文对微电网中电压波动的影响进行了评价。利用DIgSILENT软件对微电网进行了建模和仿真。研究了微电网在离网和并网两种模式下,由于可再生能源发电量的变化而产生的电压闪变问题。结果表明,微电网电压波动的主要来源是光伏发电和风力发电。当微电网以离网模式运行时,这种情况更加严重。在某些情况下,可再生能源可以改善电压分布。

An evaluation of voltage variation and flicker severity in micro grid
This paper evaluates the effects of voltage fluctuation in a micro grid. The micro grid is modeled and simulated using the DIgSILENT software. The voltage flicker due to the variation of power productions from renewable sources in microgrid during off-grid and grid-connected mode are presented. The results indicate that the main sources of voltage fluctuation in the studied micro grid are PV and wind generations. The situation becomes worse when the microgrid is operated in off-grid mode. The renewable sources can improve voltage profiles in some cases.
