【摘要】：《關于進一步深化電力體制改革的若干意見(中發(fā)[2015]9號)》提出了“三放開,一獨立,三加強”的改革方針,并且重新定義了未來電網(wǎng)公司的職能:電網(wǎng)公司未來主要從事電力傳輸配送、電網(wǎng)投資運行、負責電網(wǎng)的系統(tǒng)安全,按照國家規(guī)定履行電力普遍服務義務,保障電網(wǎng)公平無歧視開放。同時,文件確定了“管住中間、放開兩頭”的改革方向。不僅僅是電廠與電網(wǎng)徹底分離,未來售電側(cè)增量配電網(wǎng)業(yè)務也將放開,允許新的售電主體進入售電側(cè),在已有發(fā)電企業(yè)、電網(wǎng)企業(yè)的基礎上,成立多元化的售電公司,激發(fā)售電側(cè)的市場活力。新一輪的電改將使得電網(wǎng)企業(yè)面臨更加開放的市場環(huán)境,給未來電網(wǎng)規(guī)劃和電網(wǎng)投資工作帶來新的機遇與挑戰(zhàn)。電能是經(jīng)濟新常態(tài)下我國取得發(fā)展的重要支柱。電網(wǎng)在電能的供應、輸送中起到了至關重要的作用,規(guī)劃與投資這兩個環(huán)節(jié)不但關系著當前經(jīng)濟社會的平穩(wěn)發(fā)展,還涉及到政治等方面的重大問題。電力體制改革的不斷推進使得電網(wǎng)公司面臨的外部環(huán)境會更為復雜,為了能在落實電網(wǎng)規(guī)劃工作之前,切實了解電網(wǎng)的建設和運行狀況,強化對電網(wǎng)存量資產(chǎn)、增量資產(chǎn)的精益化管理水平,亟需分析此背景下電網(wǎng)規(guī)劃與投資的新的影響因素,提出適應新一輪電改的電網(wǎng)規(guī)劃與投資決策優(yōu)化方法。相關研究能夠幫助電網(wǎng)企業(yè)在新的市場化環(huán)境中提高規(guī)劃方案的精準性,進一步提高項目的投資效益,從而實現(xiàn)企業(yè)自身的可持續(xù)發(fā)展和經(jīng)濟社會的和諧進步。本文首先從多個方面梳理了我國電力體制改革的現(xiàn)狀,并對我國電力市場化改革趨勢進行了分析;其次,結(jié)合新形勢分別研究了電力體制改革對電網(wǎng)規(guī)劃與投資的影響;最后,從三個方面對新形勢下的電網(wǎng)規(guī)劃與投資優(yōu)化決策方法進行了研究。運用系統(tǒng)動力學軟件宏觀分析電網(wǎng)規(guī)劃與投資間的反饋關系,然后結(jié)合影響因素,優(yōu)化了電網(wǎng)規(guī)劃經(jīng)濟評價方法,并且根據(jù)我國配電網(wǎng)規(guī)劃、投資實際的情況,對項目入庫、出庫方法進行優(yōu)化,建立了一套科學的項目評價指標體系,進而提出適應新一輪電力體制改革的電網(wǎng)投資決策優(yōu)化方法,實現(xiàn)規(guī)劃項目的優(yōu)選,為電網(wǎng)企業(yè)的可持續(xù)發(fā)展提供決策支持,并結(jié)合實際算例來說明提出的投資優(yōu)化決策方法的合理性。
[Abstract]:Several opinions on further deepening the reform of the electric power system (Zhongfa [2015] No. 9) put forward the reform policy of "three liberalisation, one independence and three strengthening". And redefined the functions of the future grid company: the power grid company in the future mainly engaged in power transmission and distribution, grid investment operation, responsible for the security of the power system, in accordance with national regulations to fulfill the universal service obligations of electricity, To ensure fair and open power grid without discrimination. At the same time, the document set out the reform direction of "keep in the middle and open the two ends." Not only is the power plant completely separated from the power grid, but the incremental distribution network business on the sale side will also be liberalized in the future, allowing new power sellers to enter the power sale side. On the basis of the existing power generation enterprises and power grid enterprises, they will set up diversified power sale companies. Exciting sales of the electricity side of the market vitality. The new round of electricity reform will make the power grid enterprises face a more open market environment and bring new opportunities and challenges to the future power network planning and grid investment. Electric energy is an important pillar of the development of our country under the new normal state of economy. Power grid plays an important role in the supply and transmission of electric energy. Planning and investment are not only related to the steady development of current economy and society, but also related to the major problems in politics and so on. With the continuous development of the power system reform, the external environment faced by power grid companies will be more complicated. In order to understand the construction and operation status of the power grid before the implementation of the power network planning work, and to strengthen the stock assets of the power grid, With the lean management level of incremental assets, it is urgent to analyze the new influencing factors of power network planning and investment under this background, and to put forward the optimization method of power network planning and investment decision adapting to the new round of electricity reform. Relevant research can help power grid enterprises to improve the precision of planning in the new market-oriented environment, further improve the investment efficiency of the project, so as to achieve the sustainable development of the enterprise itself and the harmonious progress of the economy and society. This paper firstly combs the current situation of electric power system reform in China from many aspects, and analyzes the trend of power market reform in our country; secondly, combining with the new situation, it studies the influence of power system reform on power network planning and investment respectively. Finally, three aspects of the new situation of power network planning and investment optimization decision-making methods are studied. The feedback relationship between power network planning and investment is analyzed macroscopically by using system dynamics software, and then the economic evaluation method of power network planning is optimized by combining the influence factors. According to the actual situation of distribution network planning and investment in our country, the project is put into storage. The method of outputting is optimized, a set of scientific project evaluation index system is set up, and the optimization method of power network investment decision is put forward to realize the optimal selection of the planning project, which adapts to the new round of electric power system reform. It provides decision support for the sustainable development of power grid enterprises and illustrates the reasonableness of the proposed investment optimization decision method with practical examples.
