Research On Power Gird Investment Strategy Of Urban Power Supply Enterprises Under New Electric Power Mechanism

The new round of power system reform has a profoundly.influence on Power Supply Enterprises by carrying out transmission and distribution price reform around nationwide,opening the incremental distribution services.The implementation of transmission and distribution price reform has had a profound impact on all the functions of power grid management,such as investment,planning and operation management.The introduction of other market players in the incremental distribution network business makes traditional power supply enterprises faces competition directly.The reform aims at promoting the upgrading of distribution network.In a word,the new power system mechanism will have a profound impact on the power grid investment business.On the time of the old power system is still effective,and the new power system mechanism has not been fully effective,it’s necessary to research the impact of new power system mechanism on the grid investment business,promote the urban power supply enterprises to accelerate the adaptation of the new power system mechanism and fullfill its economic responsibility and social responsibility.Based on the above background,the paper takes the D City Power Supply Company in the south of China as the research object,analyze the problems of urban power supply enterprises in the grid investment business under the new power system and put forward comprehensive solution.The research include four following aspects.First,apply PEST method on the city power supply company’s macro investment environment analysis,further analyze the impact of new power reform policy on the power grid investment business,the problems which form in the new power mechanism are put forward;Second,based on the system dynamics method,analyze the optimization goal of power grid investment scale optimization and the optimization logic are designed.Consider the factors of supervision,price adjustment,business conditions and their interaction,the grid transmission and distribution price&gird investment model is establish,and the optimization strategy of the scale of the regulatory investment are put forward,simulation and suggestion are implemented.Thirdly,analyzes the current situation of the investment structure of D City,the grid investment structure optimization is designed,the impact of business goals on grid investment is modeled and analyzed.The optimization plan of the structure and the optimization of the investment and management ability of the city of D City power supply is put forward.Finaly,based on the analysis of the pilot situation of the incremental distribution network in the country,the types of incremental distribution network are summarized,combined with the development of the distribution network,analyze of possible incremental distribution network pilot,incremental distribution network investment decision-making ideas is established,the current specially distribution network planning technical and economic analysis are carried,the incremental distribution business investment strategy and competitive strategy are put forward.
