【摘要】：隨著社會發(fā)展,化石能源儲量日益枯竭,能源危機將成為一個巨大挑戰(zhàn)。因此,為了保證能源的長期穩(wěn)定供應,世界各國大力發(fā)展可再生能源。可再生能源并網(wǎng)運行規(guī)模的增大為電力系統(tǒng)調(diào)峰與備用服務帶來了巨大的沖擊。本論文的前兩章簡單講述了國內(nèi)外現(xiàn)有的調(diào)峰模式,比較了不同的調(diào)峰模式的優(yōu)勢與不足,著重闡述了國內(nèi)外基于需求側管理的調(diào)度模式的情況。鑒于調(diào)峰問題是目前可再生能源并網(wǎng)下,其出力的不確定性為電網(wǎng)帶來的影響,針對可再生能源功率預測與消納能力的研究一直是重要的研究方向。隨著計量與通信手段的不斷發(fā)展,高級量測體系的廣泛應用,電網(wǎng)調(diào)度對接納可再生能源并網(wǎng)后產(chǎn)生的調(diào)峰與備用問題的解決方法也不斷改進,以用來改善電網(wǎng)的可靠性與經(jīng)濟性。分布式電源也越來越多的應用到普通用戶,電動汽車等可調(diào)度負荷的加入也為系統(tǒng)需求側提供了更多的可控資源。本文對這些新能源的經(jīng)濟性、可靠性以及可能的調(diào)度方式進行了總結,并對可再生能源以及儲能設備與負荷之間的協(xié)調(diào)能力進行了歸納,并提出了協(xié)調(diào)手段需要的技術支持以及發(fā)展方向。 根據(jù)目前的發(fā)展形勢,可再生能源并網(wǎng)以及其在能源結構中比例的上升必然是未來的趨勢,提高調(diào)度水平,挖掘更多的調(diào)峰資源將成為重中之重。本文提出了源荷協(xié)調(diào)的調(diào)峰模式,并通過MATLAB建立了基于用戶滿意度評價以及需求側管理的虛擬發(fā)電廠模型,根據(jù)IEEE30節(jié)點算例進行了仿真驗證,表明了在考慮用戶電費削減的激勵下,競價上網(wǎng)的模式有效的降低了系統(tǒng)負荷的波動。 在文章最后,針對黑龍江電網(wǎng)調(diào)峰情況的分析,在考慮到經(jīng)濟因素與發(fā)展空間因素的前提下,為其提出了增加可中斷負荷等建議,經(jīng)實際驗證,調(diào)峰帶來的綜合效益有明顯改善。
[Abstract]:With the development of society and the depletion of fossil energy reserves, the energy crisis will become a great challenge. Therefore, in order to ensure the long-term stable supply of energy, countries all over the world vigorously develop renewable energy. The increase of the scale of renewable energy grid operation has brought great impact to the power system peak shaving and backup service. The first two chapters of this paper briefly describe the existing peak-shaving modes at home and abroad, compare the advantages and disadvantages of different peak-shaving modes, and focus on the situation of demand-side management-based scheduling mode at home and abroad. In view of the fact that the problem of peak shaving is a problem of renewable energy and its impact on the power grid due to the uncertainty of its output, the research on the power prediction and absorption capacity of renewable energy has been an important research direction. With the continuous development of metrology and communication means and the wide application of advanced measurement system, the solutions to the problems of peak shaving and standby caused by grid dispatching after receiving renewable energy are also improved. To improve the reliability and economy of power grid. Distributed power supply is more and more applied to ordinary users. The addition of schedulable load such as electric vehicles also provides more controllable resources for the system demand side. In this paper, the economy, reliability and possible scheduling methods of these new energy sources are summarized, and the coordination ability between renewable energy sources and energy storage equipment and loads is also summarized. The technical support and development direction of coordination means are put forward. According to the current development situation, the increase of renewable energy grid and its proportion in the energy structure will be the trend in the future. It will become the most important task to improve the dispatching level and excavate more peak-shaving resources. In this paper, the peak shaving mode of source load coordination is put forward, and a virtual power plant model based on user satisfaction evaluation and demand-side management is established by MATLAB. The simulation results are verified by an example of IEEE 30 node. The results show that the mode of bidding can reduce the fluctuation of system load effectively. At the end of the paper, according to the analysis of peak regulation in Heilongjiang power network, considering the economic factors and development space factors, the paper puts forward some suggestions such as increasing interruptible load for Heilongjiang power grid, which has been verified by practice. The comprehensive benefit brought about by peak-shaving is obviously improved.
