Comprehensive benefit analysis method based on intelligent power distribution network cost and profit model

Abstract

The invention provides a comprehensive benefit analysis method based on an intelligent power distribution network cost and profit model. The method includes the steps that constitution of intelligent power distribution network equipment assets is selected, and functions or effects which can be achieved by intelligent power grid assets are matched; according to an internal operation mechanism and an external market mechanism of a system module, cost and profit analysis is conducted on an intelligent power distribution network; profits are evaluated through the economic evaluation method; on the basis of quantitative analysis of functions and profits of components of the intelligent power distribution network, linear and invisible investment profits of the intelligent power distribution network are comprehensively considered, the intelligent power distribution network cost and profit model is built, and the comprehensive benefit analysis method based on the intelligent power distribution network cost and profit model is built. By means of the method, economic benefits and environment benefits of the intelligent power distribution network are comprehensively evaluated, cost effectiveness is effectively quantified, return on investment of demonstration projects is measured, and important decision reference is provided for power grid enterprises in popularization of intelligent power distribution network projects.

Description

technical field [0001] The invention relates to the technical field of comprehensive benefit analysis of smart grids, in particular to a comprehensive benefit analysis method based on a cost-benefit model of a smart distribution network. Background technique [0002] As the realistic basis for the sustainable development and commercialization of smart grid projects, smart grid technologies such as microgrids, active distribution networks, and energy Internet are strongly supported by national policies, and their technologies and equipment are becoming more and more mature. However, the current universal smart grid project evaluation index system and benefit evaluation methods at home and abroad lack consideration of comprehensive benefits such as smart grid economic benefits, investment and cost analysis, or environmental energy conservation and emission reduction. It is difficult to give different technologies and methods. The degree of influence of each equipment compositi...

Problems solved by technology

A preliminary framework for the comprehensive evaluation index system for the technological advancement and development effect of the smart grid; an evaluation index system for identifying the economic benefits of the smart grid from the aspects of power generation, power grid, electricity consumption and other economic benefits; from investment, operation, maintenance Systems and methods have been proposed to analyze the impact of smart grid investment and construction on power grid companies from two aspects, such as cost and equipment life, and power demand, but only evaluate smart distribution networks from macro indicators such as reliability and economy. The benefits of the project, there are deficiencies in the theoretical research, divorced from the actual engineering
