【摘要】：低碳背景下,電力行業(yè)作為最大的碳排放源,必須肩負(fù)起節(jié)能減排主力軍的重任,所以,構(gòu)建低碳電力系統(tǒng)是電力行業(yè)的必然選擇。由于“碳鎖定效應(yīng)”的存在,要構(gòu)建低碳電力系統(tǒng),其首要前提是要實(shí)現(xiàn)電力系統(tǒng)的科學(xué)合理規(guī)劃。傳統(tǒng)的電源與電網(wǎng)分立規(guī)劃模式已不適應(yīng)電力系統(tǒng)發(fā)展趨勢,更具低碳特性的廠網(wǎng)協(xié)調(diào)規(guī)劃模式將逐漸取代原有規(guī)劃模式。電力規(guī)劃模式、低碳技術(shù)以及碳排放政策等是構(gòu)建低碳電力系統(tǒng)的內(nèi)外部驅(qū)動因素,但對低碳電力系統(tǒng)潛在的效益進(jìn)行系統(tǒng)評估將能極大地推動低碳電力系統(tǒng)的建設(shè)與發(fā)展。 本文采用系統(tǒng)動力學(xué)方法對廠網(wǎng)協(xié)調(diào)規(guī)劃模式下低碳電力系統(tǒng)的效益實(shí)施評估。首先研究了廠網(wǎng)協(xié)調(diào)規(guī)劃模式與低碳電力系統(tǒng)的構(gòu)建。著重分析了低碳要素的引入對電力規(guī)劃的影響,并對廠網(wǎng)協(xié)調(diào)規(guī)劃模式進(jìn)行了界定,從發(fā)電側(cè)、電網(wǎng)側(cè)和用電側(cè)3個(gè)角度闡述了構(gòu)建低碳電力系統(tǒng)的途徑；其次,基于低碳電力系統(tǒng)效益的分解構(gòu)建了效益評估指標(biāo)體系,比較了不同效益評估方法的優(yōu)劣,并基于系統(tǒng)動力學(xué)方法,給出了低碳電力系統(tǒng)效益評估的總體因果循環(huán)圖；第三,從發(fā)電側(cè)、電網(wǎng)側(cè)和用電側(cè)3個(gè)環(huán)節(jié)構(gòu)建了低碳電力系統(tǒng)效益評估模型；最后,以福建省為對象,測算了2011-2020年福建省建設(shè)低碳電力系統(tǒng)獲得的經(jīng)濟(jì)效益、碳減排效益和社會效益。 研究結(jié)果表明,廠網(wǎng)協(xié)調(diào)規(guī)劃模式下的低碳電力系統(tǒng)具有顯著的綜合效益。這有利于人們充分認(rèn)識到低碳電力系統(tǒng)各方面潛在的效益,提高相關(guān)投資方對低碳電力系統(tǒng)的投資力度,從而加快低碳電力系統(tǒng)的建設(shè)步伐。
[Abstract]:Under the low carbon background, the electric power industry, as the largest carbon emission source, must shoulder the main task of energy saving and emission reduction. Therefore, the construction of low-carbon power system is the inevitable choice of the power industry. Because of the "carbon locking effect", the most important prerequisite to build a low-carbon power system is to realize the scientific and reasonable planning of the power system. The traditional power supply and grid separation planning model is not suitable for the development trend of power system. The more low-carbon power plant and grid coordination planning model will gradually replace the original planning model. The power planning mode, low-carbon technology and carbon emission policy are the internal and external driving factors to construct low-carbon power system. However, systematic evaluation of the potential benefits of low-carbon power system will greatly promote the construction and development of low-carbon power system. In this paper, the system dynamics method is used to evaluate the efficiency of low carbon power system under the coordinated power plant planning model. Firstly, the coordinated planning model of power plant and network and the construction of low-carbon power system are studied. The influence of the introduction of low carbon elements on power planning is analyzed emphatically, and the coordinated planning mode of power plant and power network is defined, and the way of constructing low carbon power system is expounded from three angles: generation side, grid side and power side. Secondly, based on the decomposition of low carbon power system benefit, the benefit evaluation index system is constructed, and the advantages and disadvantages of different benefit evaluation methods are compared. Based on the system dynamics method, the overall causality cycle diagram of low carbon power system benefit evaluation is given. Thirdly, a low carbon power system benefit evaluation model is constructed from three links: generation side, grid side and power side. Finally, taking Fujian Province as an example, the economic benefit, carbon emission reduction benefit and social benefit obtained from the construction of low-carbon power system in Fujian Province from 2011-2020 are calculated. The results show that the low carbon power system under the coordinated power plant planning model has significant comprehensive benefits. This will help people fully realize the potential benefits of low-carbon power system and enhance the investment of relevant investors in low-carbon power system, so as to speed up the construction of low-carbon power system.
