【摘要】：2015年3月15日,国务院下发《关于进一步深化电力体制改革的若干意见(中发〔2015〕9号)文》,提出了近期推动电力体制改革的任务：逐渐推动电价改革和理清输配电价的核算机制,包括单独核定输配电价、妥善处理电价交叉补贴等。电价改革是电力体制改革的核心,输配电价是电力产业价格链的中间环节,输配电价的改革是电价改革的核心,涉及发电企业、电网企业以及电力用户的利益。目前省级电网没有合理的输配电定价机制,没有建成独立的输配电价体系,研究适合省级电网电力市场改革新形势下的省级输配电定价机制是急需解决的关键问题。本文首先对输配电价基本理论、输配电价定价方法进行了梳理,对现有的输配电定价方法进行了比较分析。然后建立了省级电网输配电价定价模型及机制,即在目前国家提出的严格控制输配电价水平,考虑核算周期内准许收入的核定、不同电压等级的输配电成本分摊、不同电压等级总输配电成本核算和核算不同电压等级合理输配电价水平的邮票定价法的基础上,设计电网不同发展阶段可持续发展的功能激励因子,建立分阶段输配电定价机制的优化模型,包括输配电价与功能激励因子投资联动模型、未来省级电网节点电价模型等,从而进一步促进电网的可持续发展与资源的优化配置。其次,分析了目前省级电网邮票法输配电价核算的关键参数取值及政策支持,包括运行维护费、定价折旧率、有效资产的核定及税金的核定。在此基础上,对A省输配电价进行实证分析,测算输配电价改革过渡阶段前期的各年输配电价水平并进行敏感性分析。同时,对该省为减少国家大气污染的环保功能所加速进行的电网投资以促进风电、光电消纳进行分析,对此对输配电价的影响进行了较深入地分析。最后,基于A省输配电价改革趋势及输配电价的测算结果,提出了省级电网输配电价改革实施的建议和措施。
[Abstract]:15 March 2015 The State Council has issued some opinions on further deepening the reform of the electric power system (Zhongfa / 20159), proposing the task of promoting the reform of the electric power system in the near future: gradually promoting the reform of electricity prices and clarifying the accounting mechanism of transmission and distribution electricity prices. Including the separate approval of transmission and distribution price, properly deal with electricity price cross-subsidy and so on. Electricity price reform is the core of power system reform, transmission and distribution price is the intermediate link of power industry price chain, and the reform of transmission and distribution price is the core of electricity price reform, which involves the interests of power generation enterprises, power grid enterprises and power users. At present, there is no reasonable transmission and distribution pricing mechanism in provincial power grid, and an independent transmission and distribution pricing system has not been built. It is a key problem to solve urgently to study the provincial transmission and distribution pricing mechanism suitable for the new situation of power market reform in provincial power grid. In this paper, the basic theory of transmission and distribution price, the pricing method of transmission and distribution price are combed, and the existing pricing methods of transmission and distribution are compared and analyzed. Then, the pricing model and mechanism of transmission and distribution price in provincial power network are established, that is, strictly controlling the transmission and distribution price level proposed by the state at present, considering the examination and approval of permitted income in the accounting cycle, and sharing the cost of transmission and distribution with different voltage levels. On the basis of stamp pricing method of reasonable transmission and distribution price level of different voltage grades, the functional incentive factors for sustainable development of power grid at different stages of development are designed. The optimization model of transmission and distribution pricing mechanism is established, including the investment linkage model of transmission and distribution price and function incentive factor, the electricity price model of future provincial power network node, and so on, so as to further promote the sustainable development of power network and the optimal allocation of resources. Secondly, the paper analyzes the key parameters and policy support of stamp pricing calculation of provincial power grid, including maintenance fee, depreciation rate, effective assets approval and tax approval. On this basis, the transmission and distribution price of province A is analyzed empirically, and the level of transmission and distribution price in the early stage of the transitional stage of transmission and distribution price reform is calculated and sensitivity analysis is carried out. At the same time, the paper analyzes the power grid investment accelerated by the province to reduce the environmental protection function of the country's air pollution to promote wind power and photoelectricity consumption, and the influence of this on the transmission and distribution price is deeply analyzed. Finally, based on the trend of transmission and distribution price reform in province A and the calculation results of transmission and distribution price, some suggestions and measures for the implementation of transmission and distribution price reform in provincial power network are put forward.
