Evaluation and decision method for operation efficiency of power grid

Abstract

The invention relates to an evaluation and decision method for the operation efficiency of a power grid. The method comprises the following steps of: in terms of the safety and stability of the power grid, the utilization level of equipment, power supply reliability, the quality of electric energy, and asset management level and economic benefits, performing multi-layer, long-term, global and integral full-viewing-angle evaluation on the operation efficiency of the power grid by using a modern intelligent algorithm; and in terms of the safety and stability of the power grid, the utilization level of the equipment, the power supply reliability, the quality of the electric energy, promotion of coordinated development of the power grid, and the service of economic and social development, performing auxiliary decision on capital construction projects of the power grid in terms of project scores, unit investment scores and multi-target comprehensive optimization by using an optimization algorithm, and determining the sequence of the capital construction projects of the power grid, so that the operation efficiency of the power grid is improved, and decision support is provided for planning and construction of the power grid.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method for evaluating and decision-making of power grid operation efficiency. Background technique [0002] Electric power is an important industry and key field of the national economy, which is related to the national economy, the people's livelihood and energy security. Power generation and power supply enterprises undertake the major responsibility of providing safe, economical, clean, efficient and sustainable power supply for economic and social development, as well as major economic, political and social responsibilities. Measuring the operating efficiency of power grid companies not only considers the technical and economical aspects of power grid operations, but also pays attention to the political and social responsibilities undertaken by power grid operations, that is, the power supply tasks undertaken by power grid operations to ensure safety, ensure demand, and...

Problems solved by technology

However, according to the load characteristics and operation characteristics of the power grid, only the ratio of the average power of the transmission equipment to the economic power cannot fully and objectively reflect the operation efficiency of the power grid. Comprehensively analyze the operation efficiency of the power grid in terms of management level and economic benefits, promote the coordinated development of the power grid, and serve economic and social development, etc., evaluate the power grid operation from a multi-level, long-term, overall and holistic perspective, and establish a system that can fully reflect the power grid operation. Efficiency evaluation and decision-making index system, establish a comprehensive evaluation model and decision-making model for power grid operation efficiency, comprehensively evaluate the economic and social benefits of power grid operation, and build a theoretical system for power grid operation efficiency evaluation and decision-making that is recognized by all parties. policy support

[0004] At present, the evaluation of power grid operation efficiency at home and abroad mostly starts from the economic point of view and adopts non-parametric methods. The evaluation results are greatly affected by the decision-making unit, and the full ranking of the evaluation cannot be obtained and the security and stability of the power grid itself are not considered. The decision-making basis of the project mainly comes from engineering experience or power grid security and stability requirements, less consideration is given to the coordination of power grid infrastructure projects and promoting the coordinated development of power grids and serving economic and social development. The decision-making model is mainly based on investment decisions. Unchanged; no indicator system for power grid operation efficiency evaluation and decision-making has been established
