【摘要】:微電網(wǎng)內(nèi)部電力電子變換器接口型分布式電源廣泛存在.電力電子接口微源具備與傳統(tǒng)電力系統(tǒng)電源拓?fù)浣Y(jié)構(gòu)、控制方法和動(dòng)態(tài)特性的差異性,控制方法的多樣性、電力電子接口微源高滲透率將給低慣量微電網(wǎng)的協(xié)調(diào)控制和安全穩(wěn)定運(yùn)行帶來嚴(yán)峻的挑戰(zhàn).多類型微源、多類型負(fù)荷在微電網(wǎng)內(nèi)混合共存,可能引發(fā)源源耦合交互、負(fù)荷間交互以及源荷交互,不同特性的設(shè)備間相互作用將重新塑造區(qū)別與傳統(tǒng)電力系統(tǒng)的動(dòng)態(tài)響應(yīng)特性,并誘發(fā)穩(wěn)定性問題.本文首先歸納總結(jié)可再生能源滲透率不斷提升下多源多變換微電網(wǎng)典型運(yùn)行特性和存在的穩(wěn)定性問題,詳細(xì)闡述了含風(fēng)光柴儲多源多變換接口的微電網(wǎng)模塊化動(dòng)態(tài)建模方法.在此基礎(chǔ)上,給出了用于微電網(wǎng)動(dòng)態(tài)穩(wěn)定分析的特征值分析方法和基本步驟.以珠海東澳島多源多變換智能微電網(wǎng)為對象,基于提出的動(dòng)態(tài)建模方法和動(dòng)態(tài)穩(wěn)定分析方法,給出建模與分析討論結(jié)果.論文對多源多變換微電網(wǎng)系統(tǒng)動(dòng)態(tài)穩(wěn)定分析方法的論述可為微電網(wǎng)的廣泛推廣和應(yīng)用提供建模和分析理論基礎(chǔ).
[Abstract]:Power electronic converter interface distributed power generation is widely used in microgrid.The power electronic interface microsource has the difference from the traditional power supply topology, control methods and dynamic characteristics, and the diversity of control methods.The high permeability of power electronic interface microsource will bring serious challenges to the coordination control and safe and stable operation of low inertia microgrid.Multi-type micro-source and multi-type load coexist in microgrid, which may lead to source-source coupling interaction, inter-load interaction and source-load interaction.The interaction between devices with different characteristics will reshape the dynamic response characteristics of different power systems and induce stability problems.In this paper, the typical operation characteristics and stability problems of multi-source multi-transformation microgrid with increasing renewable energy permeability are summarized firstly, and the modular dynamic modeling method of micro-grid with wind-firewood multi-source multi-transformation interface is described in detail.On this basis, the eigenvalue analysis method and basic steps for dynamic stability analysis of microgrid are presented.Based on the proposed dynamic modeling method and dynamic stability analysis method, the results of modeling and analysis are given based on the multi-source and multi-transform smart microgrid in Dongao Island, Zhuhai.In this paper, the dynamic stability analysis method of multi-source and multi-transform microgrid system can provide a theoretical basis for modeling and analysis for the wide application and popularization of micro-grid.
