Power transmission network operating efficiency and benefit detection method considering new energy access

Abstract

The invention relates to a power transmission network operating efficiency and benefit detection method considering new energy access. The power transmission network operating efficiency and benefit detection method comprises the steps of: 1, laying a system establishment foundation including (1) a foundation hierarchical structure of system construction and (2) sub-goal layer determination of a system; 2, detailing a three-grade index for constructing a foundational system, constructing foundation hierarchical structure and sub-goals based on the system determined in the step 1, and detailing sub-goals, so as to determine an index layer of the system, wherein the index layer comprises equipment operating efficiency, power grid scale efficiency index, company benefit index, social benefit index and environmental protection benefit index; 3, teasing out interactional relationships among the indexes based on a comprehensive evaluation index system obtained in the step 2, and utilizing a regression analysis model for determining grading intervals of the indexes; 4, and acquiring a preliminary judgment of index operating conditions by combining with actual operation historical data of the indexes based on the index system established in the step 2 and the index grading intervals determined in the step 3, and taking a classical domain obtained according to an index reasonable operation range as the foundation of model calculation.

Description

Technical field: [0001] The invention belongs to the field of power system optimization planning and operation efficiency benefit evaluation, and in particular relates to a transmission network operation efficiency and benefit detection method considering new energy access. Background technique: [0002] With the development of our country's social economy, the updating of power technology, and the improvement of power supply quality and reliability requirements, higher requirements are put forward for the operation of the transmission network. The operation of the transmission network involves a large number of assessment indicators, which need to be evaluated scientifically, reasonably and comprehensively. Through the establishment of a transmission network efficiency and benefit evaluation system, the relevant transmission network operation can be further refined and decomposed, which is conducive to the electric power organization's effective performance of power safety,...

Problems solved by technology

At the same time, the penetration rate of new energy has increased in recent years. The current evaluation system does not consider new energy indicators systematically enough, and does not consider the efficiency and benefits of new energy power generation. Most of them only consider the environmental protection of new energy access. Its impact on the transmission network is refined and quantified into specific indicators and added to the comprehensive evaluation system
