【摘要】:目前我國(guó)可再生能源的開發(fā)利用發(fā)展迅速,但是棄風(fēng)棄光現(xiàn)象仍然嚴(yán)重,可再生能源的消納問題依舊是現(xiàn)階段能源規(guī)劃發(fā)展的主要問題。同時(shí),由于區(qū)域經(jīng)濟(jì)的發(fā)展與傳統(tǒng)能源的自然分布的不平衡,遠(yuǎn)距離輸電規(guī)模越來(lái)越大;新電改的實(shí)施,提高了能源交易的發(fā)生頻率;能源互聯(lián)網(wǎng)的逐步實(shí)踐,微電網(wǎng)逐漸成為電網(wǎng)整體中的重要組成部分,對(duì)電網(wǎng)規(guī)劃、調(diào)度控制均提出了新的要求;用電客戶的訴求多元化也為電力營(yíng)銷提出了新的要求。靈活性資源能夠積極促進(jìn)可再生能源的消納,提高能源電力供需系統(tǒng)的靈活性,降低電網(wǎng)運(yùn)行調(diào)控的難度,為電力營(yíng)銷的多元化服務(wù)提供支持。因此,進(jìn)行靈活性資源的現(xiàn)狀分析、特征評(píng)價(jià)、市場(chǎng)交易模式分析和選擇等推動(dòng)靈活性資源發(fā)展的工作亟需開展進(jìn)一步研究。論文圍繞著靈活性資源的市場(chǎng)交易模式及選擇方面,首先,簡(jiǎn)要介紹了靈活性資源的基本概念,分析了其作用機(jī)理和主要特征,總結(jié)了靈活性資源在電力系統(tǒng)中的存在形式以及現(xiàn)階段發(fā)展方面存在的問題。其次,分析了靈活性資源的成本效益構(gòu)成,構(gòu)建了考慮全壽命周期成本分?jǐn)偟撵`活性資源的市場(chǎng)-經(jīng)濟(jì)決策模型,計(jì)算靈活性資源的市場(chǎng)-經(jīng)濟(jì)決策系數(shù);然后,根據(jù)靈活性資源的五大特征需求,構(gòu)建了靈活性資源綜合評(píng)價(jià)體系,并結(jié)合了靈活性資源的現(xiàn)狀,構(gòu)建了靈活性綜合評(píng)價(jià)模型;再次,結(jié)合新電改和能源互聯(lián)網(wǎng)的實(shí)施現(xiàn)狀,分析出靈活性資源的可行市場(chǎng)交易模式,并采用環(huán)境分析、綜合評(píng)價(jià)特征排序、模式選擇原則的設(shè)計(jì),設(shè)計(jì)了靈活性資源的市場(chǎng)交易模式選擇方案;最后,以某壓縮空氣儲(chǔ)能項(xiàng)目為例對(duì)其市場(chǎng)-經(jīng)濟(jì)決策系數(shù)進(jìn)行了計(jì)算,并進(jìn)行了其靈活性的綜合評(píng)價(jià)和特征需求排序,利用市場(chǎng)交易模式選擇方案進(jìn)行了市場(chǎng)交易模式的選擇,為靈活性資源的市場(chǎng)交易模式的選擇提供了理論支持。論文創(chuàng)造性地提出靈活性綜合評(píng)估指標(biāo)體系,并分析總結(jié)出靈活性資源市場(chǎng)交易模式和選擇方案,為靈活性資源的靈活性評(píng)估、市場(chǎng)決策提供重要理論支持,對(duì)靈活性資源的發(fā)展和推廣具有重要意義。
[Abstract]:At present, the development and utilization of renewable energy in China is rapid, but the phenomenon of abandoning wind and abandoning light is still serious, and the problem of absorption of renewable energy is still the main problem of energy planning and development at the present stage.At the same time, because of the imbalance between the development of regional economy and the natural distribution of traditional energy, the scale of long-distance transmission becomes larger and larger. The implementation of new electricity reform has increased the frequency of energy transaction, the gradual practice of energy Internet,Microgrid has gradually become an important part of the whole power network, which puts forward new requirements for power network planning and dispatching control.Flexible resources can actively promote the absorption of renewable energy, improve the flexibility of energy supply and demand system, reduce the difficulty of power grid operation and regulation, and provide support for the diversified service of power marketing.Therefore, it is necessary to carry out further research on the development of flexible resources, such as the analysis of the current situation of flexible resources, the evaluation of characteristics, the analysis and selection of market transaction patterns.First of all, the paper briefly introduces the basic concept of flexible resources, analyzes its working mechanism and main characteristics.This paper summarizes the existing forms of flexible resources in power system and the existing problems in the current development.Secondly, the cost-benefit structure of flexible resources is analyzed, and a market-economy decision-making model considering the allocation of full life cycle cost is constructed to calculate the market-economic decision-making coefficient of flexible resources.According to the five characteristic requirements of flexible resources, this paper constructs a comprehensive evaluation system of flexible resources, and combines the current situation of flexible resources, constructs a comprehensive evaluation model of flexibility. Thirdly, combined with the implementation of the new electricity reform and the energy Internet,The feasible market transaction model of flexible resources is analyzed, and the market transaction mode selection scheme of flexible resources is designed by using environment analysis, comprehensive evaluation feature ranking and the design of mode selection principle.Taking a compressed air energy storage project as an example, the market-economy decision-making coefficient is calculated, and its flexibility is evaluated synthetically and the characteristic demand ranking is carried out, and the market trading mode is selected by using the market trading mode selection scheme.It provides theoretical support for the choice of market trading mode of flexible resources.The paper creatively puts forward the index system of flexibility comprehensive evaluation, and analyzes and sums up the trading mode and selection scheme of flexible resource market, which provides important theoretical support for flexibility evaluation of flexible resource and market decision.It is of great significance to the development and promotion of flexible resources.
