Research For The Controlling Of Electricity Purchasing Cost Of Provincial Power Grid Enterprise

The promulgated No.9 and its supportive documents guide the electrical network enterprise to participating market competition form regulated management in the past.As independent market participator,The market's behavior of power grid enterprise always caught the attention of all stakeholders during a transition period.With the further deepening of the reform of electricity market,The environment for power grid enterprises to purchase electricity become more and more complexity.In the electricity market,uncertainty factor's impact on electricity purchasing cost is more and more obvious.The electricity purchasing cost of power grid enterprise has accounts for more than two-thirds of its business cost,The results of power purchase work can directly affect that whether the power grid enterprises can perform their social responsibility,ensure the normal power supply,and to carry out the national strategy of energy conservation and emissions reduction or not,and it also directly related to the benefit of power grid companies.How to control the electricity purchase cost is an improving business performance in the future.There are several aspects included in this paper: firstly,look up the related domestic and foreign literature in terms of power grid enterprise cost control,analyzing the common methods of cost control.Furthermore this paper introduced and reviewed the cost control methods in electricity purchase for power grid enterprise.Secondly,this paper expounds the cost control theory,regulation economics theory and regulation theory of purchasing management,these are all the theoretical support for this paper.Thirdly,analyzed the particularity of electric power commodity that different from general merchandise and the environment for power grid enterprises to purchase electricity.And according to the A provincial power grid's electricity purchase in 2015 to analyzing this problem,raising the question that should to be solve.Fourthly,established the electricity purchasing cost control model,and conduct the analyses of numerical example for power grid enterprise's unit power purchase costs among various kinds of uncertain situation.Under the premise that to meet various constraint conditions,concluded the optimal power purchase plan in order to reducecost.Fifth,according to previous research,put forward the method of electricity purchasing cost control strategy,and proceed the strategy analysis for electricity purchasing from province to province.Provided some reference basis for the electricity purchasing of provincial power grid enterprises.
