发布时间：2019-02-11 10:40
【摘要】：《关于进一步深化电力体制改革的若干意见(中发[2015]9号)》提出了“三放开,一独立,三加强”的改革方针,并且重新定义了未来电网公司的职能:电网公司未来主要从事电力传输配送、电网投资运行、负责电网的系统安全,按照国家规定履行电力普遍服务义务,保障电网公平无歧视开放。同时,文件确定了“管住中间、放开两头”的改革方向。不仅仅是电厂与电网彻底分离,未来售电侧增量配电网业务也将放开,允许新的售电主体进入售电侧,在已有发电企业、电网企业的基础上,成立多元化的售电公司,激发售电侧的市场活力。新一轮的电改将使得电网企业面临更加开放的市场环境,给未来电网规划和电网投资工作带来新的机遇与挑战。电能是经济新常态下我国取得发展的重要支柱。电网在电能的供应、输送中起到了至关重要的作用,规划与投资这两个环节不但关系着当前经济社会的平稳发展,还涉及到政治等方面的重大问题。电力体制改革的不断推进使得电网公司面临的外部环境会更为复杂,为了能在落实电网规划工作之前,切实了解电网的建设和运行状况,强化对电网存量资产、增量资产的精益化管理水平,亟需分析此背景下电网规划与投资的新的影响因素,提出适应新一轮电改的电网规划与投资决策优化方法。相关研究能够帮助电网企业在新的市场化环境中提高规划方案的精准性,进一步提高项目的投资效益,从而实现企业自身的可持续发展和经济社会的和谐进步。本文首先从多个方面梳理了我国电力体制改革的现状,并对我国电力市场化改革趋势进行了分析;其次,结合新形势分别研究了电力体制改革对电网规划与投资的影响;最后,从三个方面对新形势下的电网规划与投资优化决策方法进行了研究。运用系统动力学软件宏观分析电网规划与投资间的反馈关系,然后结合影响因素,优化了电网规划经济评价方法,并且根据我国配电网规划、投资实际的情况,对项目入库、出库方法进行优化,建立了一套科学的项目评价指标体系,进而提出适应新一轮电力体制改革的电网投资决策优化方法,实现规划项目的优选,为电网企业的可持续发展提供决策支持,并结合实际算例来说明提出的投资优化决策方法的合理性。
[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.
