Comprehensive assessment method for running of intelligent power distribution network

Abstract

A comprehensive assessment method for running of an intelligent power distribution network includes the steps of firstly, building a comprehensive assessment index system according to the running characteristic of the intelligent power distribution network; secondly, defining application range of the assessment method in terms of preference information, quantity of plans and relation between the quantity of plans and the quantity of attributes on the basis of investigation of the conventional comprehensive assessment method for the power distribution network, selecting the analytic hierarchy process, the fuzzy comprehensive evaluation method and the Delphi method as theoretical supports for comprehensive assessment according to real condition of assessment of running of the intelligent power distribution network, and on the basis of the three methods, providing comprehensive assessment methods and processes which include important links such as weight setting, scoring standard setting and assessment result analyzing. The comprehensive assessment index system relates to five indexes of safety, reliability, economy, high quality and intellectuality. The comprehensive assessment method has high practicability, feasibility and promotion and application value, and can provide important basis for scheduling and planning of the power distribution network and for management staff to make decision.

Description

technical field [0001] The invention belongs to the technical field of intelligent distribution network and is used for evaluating the operation of the intelligent distribution network, wherein the comprehensive evaluation method can also be used for assisting decision-making in traditional distribution network evaluation and planning schemes. Background technique [0002] Smart grid represents the latest direction of power grid development and transformation. At present, many countries in Europe and the United States are actively planning to promote the construction of smart grid. In May 2009, the State Grid Corporation announced the development plan of "smart grid" to the public for the first time, and initially disclosed its construction timetable, which indicated that the construction of China's smart grid was officially put on the agenda. [0003] Today, my country's smart grid construction has achieved certain results, and several demonstration parks represented by sma...

Problems solved by technology

[0006] The problem to be solved by the present invention is: the power grid is a huge system, and the data obtained directly from the power grid cannot fully reflect the state of the power grid. Since every adjustment of the power grid will have an impact on the overall operation, technicians cannot Adjusting the operation of the power grid by individual power grid parameters requires a comprehensive evaluation method to help technicians analyze and evaluate the overall state of the power grid, and then use it for power grid dispatching, planning, and operation.
