Power network development capability comprehensive diagnosis index system establishment method

Abstract

The invention provides a power network development capability comprehensive diagnosis index system establishment method. The method comprises the following steps of 1, establishing a target layer, which is a power network development diagnosis index system; 2, establishing a control layer, which comprises 6 indexes including a power network scale, a power network structure, utilization efficiency, safety reliability, an equipment level and an operation environment; 3, establishing a network layer, which comprises 39 indexes corresponding to the indexes of the control layer respectively; 4, calculating weights omega i of the indexes based on a analytic network process; 5, building an aggregation model; and 6, displaying a diagnosis result. According to the method, in combination with a power network development law, starting from limitations of power network development conditions and external factors, related indexes influencing power network development are selected, and from the perspective of long-term power network development, the limitations of resources such as energy resources, environments, lands and the like on the power network development are considered, so that an innovative index is proposed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for constructing a comprehensive diagnosis index system of power grid development capability. Background technique [0002] In 2015, the State Council's "Several Opinions on Further Deepening the Reform of the Electric Power System" Document No. 9 "Enhancing the coverage, authority and scientificity of planning...Establishing a working mechanism for planning implementation inspection, supervision, evaluation, and assessment" put forward requirements for power grid development diagnosis , grid development diagnosis should provide objective technical support for grid development planning, and is an important decision-making basis for improving grid management level; at the same time, in accordance with the requirements of lean and refined management of State Grid Corporation, grid development diagnosis has become one of the special tasks every year . The most basi...

Problems solved by technology

[0003] At present, there are few existing researches at home and abroad that conduct in-depth analysis and diagnosis of regional power grids systematically and overall. Most of them analyze and study power grids from single aspects such as power grid security and power supply quality, and the coverage of diagnosis is not comprehensive enough.
