Precise Investment Of Power Grid To Adapt To The Reform Of Transmission And Distribution Price

Since the reform of the new electric power system,the measures for supervision and examination of transmission and distribution pricing cost(Trial Implementation)and the measures for transmission and distribution pricing of provincial power grid(Trial Implementation)have been issued successively,marking that China has initially established a scientific,standardized and transparent transmission and distribution pricing supervision system.Based on the principle of "permitted cost plus reasonable income",the modern incentive supervision concept is introduced to encourage grid enterprises to reduce investment and reduce investment impulse.In view of the necessity of research on the precise investment strategy of high-quality power grid under the dynamic regulation of transmission and distribution price,this paper first summarizes the research status of domestic and foreign scholars on the reform of transmission and distribution price and the investment decision-making of power grid,from the pricing mechanism of transmission and distribution price,the regulation mode of transmission and distribution price,the impact of transmission and distribution price reform on power grid,the prediction of power grid investment demand,and the prediction of power grid investment capacity Then,the basic theory of transmission and distribution price pricing and the pricing mechanism of transmission and distribution price in China are discussed.In view of the problems that the top-level design of reform needs to be improved and deepened,the incentive and restriction of power grid enterprises are still insufficient,and the adaptability of all parties to reform needs to be further improved,the future development of transmission and distribution price reform in China is summarized Secondly,it identifies the influencing factors of power grid investment from two aspects of investment demand and investment capacity,and qualitatively analyzes the dynamic influence mechanism of power grid investment under the pricing mechanism of transmission and distribution price based on the interpretative structural model;then,it forecasts the demand of power grid investment,taking the growth of regional electricity,the growth of maximum load,the demand of equipment renovation and the growth of regional GDP as The multivariate linear regression model is constructed with independent variables;then,based on the system dynamics model,the paper quantitatively analyzes the many influencing factors related to the power grid investment under the environment of transmission and distribution price reform,and models the transmission and distribution price and power grid profit The stack flow diagram is drawn by Runhe investment capability and other modules,and the simulation model of power grid investment decision is constructed to study the dynamic feedback process of power grid investment under the transmission and distribution pricing mechanism.Finally,considering all aspects of power grid investment decision-making as a whole,a power grid investment strategy of "combining hardness with softness" is proposed,and the corresponding dynamic adjustment mechanism of power grid investment decision-making is formulated by using the concept of full cycle dynamic management.Through the analysis and research,this paper draws the conclusion that the power grid investment and power growth have a significant impact on the transmission and distribution price,while the transmission and distribution price also has an impact on the next round of power grid investment,and puts forward the corresponding power grid investment strategy under the environment of transmission and distribution price reform,which is conducive to the realization of controllable,controllable and under control of power grid investment decision.
