【摘要】：我國能源負荷逆向分布的特點決定了中國能源流將呈現(xiàn)“由北到南,自西向東”的基本格局。為應對這種基本格局,基于特高壓交直流的跨省跨區(qū)輸電成為電網(wǎng)發(fā)展的重點領域。目前已建好的賓金直流、錦蘇直流、復奉直流將西南大量的水電輸送到東部負荷區(qū)。由于外送水電既包括大型流域水電也包含送端省份大量小型的徑流式水電(通常表現(xiàn)為水電外送電力交易),一般大型流域水電都配有年度或季度調(diào)節(jié)水庫,將中長期的水庫調(diào)度與大量小型徑流式水電共同外送進行深入融合是進一步提升水力資源和電網(wǎng)利用效率的有效手段之一。另一方面,由于送端電網(wǎng)缺乏負荷需求,配套電源基本全部外送,這造成了送端電網(wǎng)結構薄弱,電力通常經(jīng)過幾個關鍵斷面然后匯集到換流站實現(xiàn)外送,因此這些關鍵斷面就成了外送的“容量關卡”。雖然斷面的輸電限額與電網(wǎng)運行方式、負荷需求、開機方式等共同決定,但檢修計劃的制定則直接影響斷面?zhèn)鬏敼β�。在條件允許的情況下,檢修計劃與一次能源的豐枯特性及電力外送計劃進行有序配合對水電的充分消納具有重要意義。本論文以實現(xiàn)解決流域調(diào)度(在此主要涉及水庫蓄水、消落的水位調(diào)節(jié)問題)、外送計劃及相關電網(wǎng)檢修的協(xié)調(diào)配合為目標,在中長期時間范疇內(nèi),尋找三者之間的協(xié)調(diào)策略,構建包含三者的一體化協(xié)調(diào)模型,通過模型的求解確定最佳配合方案。主要研究內(nèi)容和成果包括:(1)量化分析水庫運行水位、區(qū)間流量對電站出力和蓄能能力的影響,分析電站組間出力比例關系和蓄能轉(zhuǎn)換關系等耦合關系的特點和模式,提出梯級電站耦合關系的描述方法。(2)分析梯級水電水位調(diào)節(jié)、發(fā)電計劃、檢修計劃、外送計劃等業(yè)務領域的關鍵決策變量和參量,提出水電水位調(diào)節(jié)、外送計劃、檢修計劃與發(fā)電計劃的協(xié)調(diào)策略,形成適應不同決策變量和參數(shù)設置方式下的以發(fā)電計劃為核心的多業(yè)務聯(lián)合協(xié)調(diào)方法。(3)確定流域梯級水電中長期水位調(diào)節(jié)、發(fā)電計劃及檢修計劃聯(lián)合協(xié)調(diào)目標函數(shù)、約束條件,以發(fā)電計劃為紐帶,提出流域梯級水電中長期水位調(diào)節(jié)、發(fā)電計劃及檢修計劃聯(lián)合協(xié)調(diào)模型構建方法。(4)研究開發(fā)流域梯級水電中長期水位調(diào)節(jié)、發(fā)電計劃及檢修計劃聯(lián)合協(xié)調(diào)求解算法,在考慮水庫水位、區(qū)間流量及出力水平的基礎上實現(xiàn)梯級電站出力比例設置,開展對四川大型流域梯級水電大規(guī)模外送的應用場景分析,驗證模型算法的正確性和有效性。論文成果可為大型流域水電中長期水位調(diào)節(jié)、外送計劃、檢修計劃的聯(lián)合協(xié)調(diào)提供分析計算工具。充分發(fā)揮大型流域水電抽蓄能作用,實現(xiàn)區(qū)域內(nèi)不同調(diào)節(jié)能力、所屬不同調(diào)度機構的水電資源協(xié)調(diào)配合,提供大規(guī)模輸電通道利用效率,促進清潔能源消納。
[Abstract]:The reverse distribution of energy load in China determines the basic pattern of energy flow from north to south and from west to east. In order to deal with this basic pattern, transprovincial transmission based on UHV AC / DC has become a key area of power grid development. At present, Binjin DC, Jinsu DC and DC are built to transport a large amount of hydropower from southwest to the eastern load area. Since outsourced water and power supply includes both large watershed hydropower and a large number of small run-off hydropower stations in the sending provinces (usually manifested as hydropower outsourced electricity transactions), large watershed hydropower stations are generally equipped with annual or quarterly regulating reservoirs. It is one of the effective methods to further improve the efficiency of hydraulic resources and grid utilization by integrating the long-term reservoir operation with a large number of small runoff hydropower plants. On the other hand, due to the lack of load demand in the power supply network, the complete power supply is basically sent out, which leads to the weak structure of the power supply network. The power usually passes through several key sections and then converges to the converter station to realize outgoing transmission. As a result, these critical sections become outgoing "capacity points". Although the transmission quota of section is decided by the operation mode, load demand and start-up mode of the power network, the plan of maintenance and repair directly affects the transmission power of the section. If conditions permit, it is of great significance that the maintenance plan, the characteristics of primary energy supply and output, and the power delivery plan cooperate in an orderly manner for the full absorption of hydropower. The aim of this paper is to realize the coordination of river basin operation (mainly involving reservoir water storage and water level regulation), outgoing plan and maintenance of relevant power grid. In the medium and long term, the coordination strategy among the three is sought. An integrated coordination model with three components is constructed, and the optimal coordination scheme is determined by solving the model. The main research contents and achievements are as follows: (1) the effects of reservoir water level and interval discharge on the output and storage capacity of the power station are analyzed quantitatively, and the characteristics and models of the coupling relations, such as the ratio of the output force and the energy storage conversion between the groups of the power station, are analyzed. The coupling relationship of cascade hydropower stations is described. (2) the key decision variables and parameters in the fields of cascade hydropower water level regulation, generation plan, maintenance plan, outgoing transmission plan, etc., are analyzed, and the hydropower water level regulation and outgoing transmission plan are put forward. The coordination strategy between overhaul plan and generation plan is formed to form a multi-service joint coordination method with power generation plan as the core under different decision variables and parameter setting methods. (3) the medium and long-term water level regulation of cascade hydropower in river basin is determined. The power generation plan and maintenance plan jointly coordinate the objective function, restrict the condition, take the generation plan as the link, put forward the medium and long term water level regulation of cascade hydropower in river basin, The method of constructing the joint coordination model of power generation plan and maintenance plan. (4) to study the long-term water level regulation of cascade hydropower station in river basin, and to solve the algorithm of joint coordination of generation plan and maintenance plan, considering the water level of reservoir, On the basis of interval flow and output level, the output ratio of cascade hydropower stations is set up, and the application scenario of large-scale outputting of cascade hydropower stations in Sichuan large watershed is analyzed, and the correctness and validity of the model algorithm are verified. The results of this paper can provide analysis and calculation tools for the joint coordination of water level regulation, outgoing plan and maintenance plan of hydropower stations in large river basins. The utility model can give full play to the function of hydropower pumping and storage in large river basins, realize the different regulating capacity in the region, coordinate the hydropower resources of different dispatching agencies, provide large-scale transmission channel utilization efficiency, and promote clean energy consumption.
