【摘要】：隨著世界能源的枯竭,環(huán)境污染的日益嚴重,潮汐、太陽能特別是風力發(fā)電這些清潔能源得到了長足的發(fā)展。其中,風力發(fā)電蘊量豐富、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,風電在電網(wǎng)電源中所占的比例不斷提高,風電對電力系統(tǒng)的影響變得不可忽視。本文以湖南電網(wǎng)實際情況為背景,定量分析了大規(guī)模風電接入后對調(diào)峰能力的影響。 本文首先綜述了風電接入電網(wǎng)對調(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)外對接納風電的研究現(xiàn)狀,然后介紹了電力系統(tǒng)運行模擬軟件的原理及計算方法。由于對未來風電接入電網(wǎng)的分析需要,利用灰色預(yù)測GM(1,1)模型進行負荷預(yù)測,并對其模型進行了改進,在一定范圍內(nèi)取得了更好的預(yù)測效果。接著,針對風電場隨機性、難預(yù)測的特點及對系統(tǒng)調(diào)峰的影響類別,建立的風電出力情景分析模型,并提出了情景重要性指標,描述風電出力的隨機變化對電力系統(tǒng)調(diào)峰的影響程度。針對湖南省水利資源豐富的特點,提出適合枯水期的風電—水電負荷高峰互補運行策略,以及在豐水期適用的風電—水電綁定運行策略。并在湖南電網(wǎng)實際2015年規(guī)劃的邊界條件下進行模擬運行計算,驗證了策略的有效性,且定量分析了湖南電網(wǎng)2015年在風電接入后的調(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.
