【摘要】：隨著世界能源的枯竭,環(huán)境污染的日益嚴(yán)重,潮汐、太陽能特別是風(fēng)力發(fā)電這些清潔能源得到了長足的發(fā)展。其中,風(fēng)力發(fā)電蘊(yùn)量豐富、起步較早、技術(shù)成熟已經(jīng)成為發(fā)展清潔能源的首要選擇。近年來,風(fēng)電在電網(wǎng)電源中所占的比例不斷提高,風(fēng)電對(duì)電力系統(tǒng)的影響變得不可忽視。本文以湖南電網(wǎng)實(shí)際情況為背景,定量分析了大規(guī)模風(fēng)電接入后對(duì)調(diào)峰能力的影響。 本文首先綜述了風(fēng)電接入電網(wǎng)對(duì)調(diào)峰的影響,各類其他電源為電網(wǎng)調(diào)峰的特性,目前國內(nèi)外對(duì)接納風(fēng)電的研究現(xiàn)狀,然后介紹了電力系統(tǒng)運(yùn)行模擬軟件的原理及計(jì)算方法。由于對(duì)未來風(fēng)電接入電網(wǎng)的分析需要,利用灰色預(yù)測(cè)GM(1,1)模型進(jìn)行負(fù)荷預(yù)測(cè),并對(duì)其模型進(jìn)行了改進(jìn),在一定范圍內(nèi)取得了更好的預(yù)測(cè)效果。接著,針對(duì)風(fēng)電場(chǎng)隨機(jī)性、難預(yù)測(cè)的特點(diǎn)及對(duì)系統(tǒng)調(diào)峰的影響類別,建立的風(fēng)電出力情景分析模型,并提出了情景重要性指標(biāo),描述風(fēng)電出力的隨機(jī)變化對(duì)電力系統(tǒng)調(diào)峰的影響程度。針對(duì)湖南省水利資源豐富的特點(diǎn),提出適合枯水期的風(fēng)電—水電負(fù)荷高峰互補(bǔ)運(yùn)行策略,以及在豐水期適用的風(fēng)電—水電綁定運(yùn)行策略。并在湖南電網(wǎng)實(shí)際2015年規(guī)劃的邊界條件下進(jìn)行模擬運(yùn)行計(jì)算,驗(yàn)證了策略的有效性,且定量分析了湖南電網(wǎng)2015年在風(fēng)電接入后的調(diào)峰盈余容量。
[Abstract]:As the world energy depletion, environmental pollution is becoming increasingly serious, especially the tides, solar wind power generation these clean energy has got considerable development. The rich wind power reserves started early, mature technology has become the first choice for the development of clean energy. In recent years, wind power accounted for the proportion of power grid continuously improve the impact of wind power on the power system become can not be ignored. This paper is based on the actual situation of Hunan power grid, the quantitative analysis of the influence of large scale wind power integration capability of peak shaving.
This paper reviews the influence of wind power on the peak, various other power characteristics of power peaking, at home and abroad research status of nano docking of wind power, and then introduces the principle and calculation method of the operation of the software simulation of power system. Due to the wind in the future electric analysis of access networks, using the grey forecasting GM (1,1) model in load forecasting, and the model is improved to obtain a better forecasting effect in a certain range. Then, according to the random characteristic of wind farm, difficult to predict and influence on peak categories, scenario analysis model of wind power output is established, and put forward the importance of situational influence index. Describe the random variation of wind power output on the peaking power system. According to the characteristics of water resources in Hunan province is rich in resources, suitable for dry season wind power and hydropower peak load complementary operation strategy, as well as in abundance The wind power and water power binding operation strategy suitable for water period is applied. The simulated operation calculation is carried out under the actual boundary conditions of Hunan power grid in 2015. The effectiveness of the strategy is verified, and the peak load capacity of Hunan power grid in 2015 is quantitatively analyzed.
