Abstract
With the orderly advancement of power system reform and the rapid development of incremental power distribution pilots, the investment process of power grid companies has become more and more transparent and standardized. However, in the current fierce environment, how to maintain certain economic benefits in various regional distribution networks has become a problem of concern. This paper establishes a distribution network asset economic index system from the three dimensions of investment cost, operating cost, and economic benefit. The hierarchical structure of indicators is clarified based on the interpretative structural model, and the economic level is measured based on the improved analytical hierarchy process AHP-fuzzy evaluation model. Finally, the analysis of calculation examples shows that: (1) The investment cost and operating cost of the distribution network indirectly affect the economic benefits of the power grid by affecting the electricity sales. (2) The economic levels of the distribution network in the three regions of X, Y, and Z are good, medium, and poor. The region X needs to strengthen the management of distribution network investment, and the region Y continues to improve the economy from all aspects of cost and income. The first thing in region Z is to improve the level of economic efficiency.
Highlights
With the acceleration of the construction of new infrastructure, there are more and more important power users such as high-precision manufacturing enterprises in urban areas
The region X needs to strengthen the management of distribution network investment, and the region Y continues to improve the economy from all aspects of cost and income
The operating cost indicators and investment cost indicators of the bottom layer L4 and L5 affect the cost of power transformation and transmission per unit capacity, and the influence relationship of economy is transmitted to the unit investment, increased power supply and load, until the economic benefit index of the last level
Summary
With the acceleration of the construction of new infrastructure, there are more and more important power users such as high-precision manufacturing enterprises in urban areas. The analysis of calculation examples shows that: (1) The investment cost and operating cost of the distribution network indirectly affect the economic benefits of the power grid by affecting the electricity sales. This paper establishes a general distribution network asset economic index system from the three dimensions of investment cost, operating cost, and economic benefit, as shown in figure 1.
