【摘要】：目前隨著環(huán)境和能源問題的逐漸凸顯,風電作為清潔能源具有分布廣泛且永不枯竭的特點,已經(jīng)在國內外實現(xiàn)大規(guī)模發(fā)展,從各種可再生能源中脫穎而出。但由于自然風的隨機性和間歇性等特點,造成風機出力可能在短時間內大幅度波動,它的大規(guī)模并網(wǎng)必將對電網(wǎng)產(chǎn)生沖擊和影響,主要體現(xiàn)在電網(wǎng)的安全運行穩(wěn)定、電能質量以及調度控制等方面。 赤峰市位于內蒙古自治區(qū)東南部、蒙冀遼三省區(qū)交匯處,地域遼闊,風能資源豐富,全市易開發(fā)的風能資源達1000萬千瓦以上。但目前赤峰電網(wǎng)本身已存在調峰困難等特點,為了促進風電事業(yè)在赤峰地區(qū)健康協(xié)調發(fā)展,本文結合當前電網(wǎng)風電實際運行情況,通過現(xiàn)場實際調研,在閱讀大量國內外相關文獻資料的基礎上,提出了一種基于負荷響應的風電消納方法,通過分析電網(wǎng)負荷水平、負荷特性、區(qū)內外電源對區(qū)內調峰影響、跨區(qū)聯(lián)絡線參與電網(wǎng)調峰模式以及風電機組的性能和運行特性等,開展了對含風電電網(wǎng)調峰能力的計算,隨后從改善電價方案、直接負荷控制項目與負荷聚集商機制三個角度,提出了需求響應綜合方案建議,完善電力需求側管理,促進風電在網(wǎng)內的消納。
[Abstract]:With the increasingly prominent environmental and energy problems, wind power, as a clean energy, has been widely distributed and never exhausted. It has achieved large-scale development at home and abroad, and stands out from all kinds of renewable energy sources. However, due to the randomness and intermittence of natural wind, the output of fan may fluctuate in a short period of time, and its large-scale grid connection will certainly have an impact and influence on the power grid, mainly reflected in the stability of the safe operation of the power network. Power quality and scheduling control. Chifeng City is located in the southeast of Inner Mongolia Autonomous region, the intersection of three provinces and regions in Inner Mongolia, Hebei and Liaoning provinces, the region is vast, the wind energy resources are rich, and the wind energy resources easily developed in the whole city reach more than 10 million kilowatts. In order to promote the healthy and coordinated development of wind power industry in Chifeng area, this paper combines the actual operation of wind power system in the current grid, through the actual investigation on the spot, in order to promote the healthy and coordinated development of wind power industry in Chifeng area. On the basis of reading a large amount of relevant domestic and foreign literature, a wind power dissipation method based on load response is put forward. By analyzing the load level, load characteristics, and the influence of internal and external power sources on peak shaving in the area, a method of wind power dissipation based on load response is proposed. The cross-zone tie lines participate in the mode of peak shaving and the performance and operation characteristics of wind turbines, etc., and carry out the calculation of the peak shaving capacity of the grid with wind power. Then, from the three angles of improving electricity price scheme, direct load control project and load aggregator mechanism, The comprehensive proposal of demand response is put forward to improve the power demand side management and promote the wind power consumption in the grid.
