【摘要】：近年來,面對化石能源的日益枯竭及其對環(huán)境的影響,開發(fā)清潔的可再生能源成為發(fā)展需要,這促使分布式發(fā)電技術(shù)成為現(xiàn)代電力系統(tǒng)發(fā)展的趨勢之一。但同時,分布式電源的引入改變了現(xiàn)行配電網(wǎng)的結(jié)構(gòu),必然會對系統(tǒng)的穩(wěn)定運行產(chǎn)生一系列不可避免的影響。因此,研究分布式電源并網(wǎng)對配電網(wǎng)的影響十分必要,對電壓穩(wěn)定性的研究尤為重要。 本文首先介紹了幾種常見的分布式電源,以及分布式電源并網(wǎng)后對配電網(wǎng)電壓穩(wěn)定性影響的研究背景和發(fā)展現(xiàn)狀。對含分布式電源配電網(wǎng)的靜態(tài)電壓穩(wěn)定進行分析,根據(jù)分布式電源的工作原理、運行方式,建立了不同分布式電源、配電網(wǎng)和負荷的穩(wěn)態(tài)模型,并將分布式電源劃分為PQ、P-Q(V)、PI、PV四種節(jié)點類型,給出了分布式電源接入下配電網(wǎng)潮流計算模型在潮流計算中的處理方法。 其次以靜態(tài)電壓穩(wěn)定性分析的理論為基礎(chǔ),構(gòu)建了一種基于潮流解存在性的靜態(tài)電壓穩(wěn)定性指標。在MATLAB仿真環(huán)境下,分別建立了風力發(fā)電機組和光伏發(fā)電系統(tǒng)模型,通過IEEE33節(jié)點算例進行基于關(guān)聯(lián)矩陣自乘的前推回代潮流計算,實現(xiàn)了對指標的求解并對其有效性進行仿真驗證。 最后,在指標求解的基礎(chǔ)上,分別從分布式電源的并網(wǎng)容量、并網(wǎng)位置、功率因數(shù),以及分布式電源類型出發(fā),研究不同分布式電源接入后對配電系統(tǒng)靜態(tài)電壓穩(wěn)定性的影響,分析總結(jié)規(guī)律,并找出了系統(tǒng)中的電壓敏感節(jié)點。
[Abstract]:In recent years, in the face of the increasing depletion of fossil energy and its impact on the environment, the development of clean renewable energy has become a development requirement, which makes the distributed generation technology become one of the trends of modern power system development. At the same time, the introduction of distributed power supply has changed the structure of the current distribution network, and will inevitably run the stable operation of the system. Therefore, it is necessary to study the influence of distributed generation interconnection on distribution network, and the study of voltage stability is particularly important.
This paper first introduces several common distributed power sources, and the research background and development status of the distribution network voltage stability after the distributed power grid connected to the network. The static voltage stability of distribution network with distributed power supply is analyzed. According to the working principle and operation mode of distributed power supply, different distributed power supply and distribution are established. The network and load steady state model, and divide the distributed power into four kinds of node types: PQ, P-Q (V), PI, PV, and the processing method of power flow calculation model in distribution network is given in the distribution network.
Secondly, based on the theory of static voltage stability analysis, a static voltage stability index based on the existence of power flow solution is constructed. In the MATLAB simulation environment, the model of wind turbine and photovoltaic power generation system is set up respectively. The calculation of the forward back generation power flow based on the correlation matrix self multiplying is carried out by the IEEE33 node example. The index is solved and its validity is verified by simulation.
Finally, on the basis of the index solution, the effects of different distributed power sources on the static voltage stability of the distribution system are studied from the grid capacity, the grid position, the power factor, and the type of distributed power, and the voltage sensitive nodes in the system are found out.
