Comprehensive energy system scheduling evaluation method and system based on carbon emission management

Abstract

The invention discloses a comprehensive energy system scheduling evaluation method based on carbon emission management. Power supply basic information and power load basic information of a power system, natural gas network basic information and natural gas supplier basic information of a natural gas system and natural gas load basic information are collected in real time; establishing a comprehensive low-carbon index of the comprehensive energy system, establishing an optimal scheduling model of the comprehensive energy system according to the comprehensive low-carbon index, calculating to obtain a scheduling strategy of the comprehensive energy system through an alternating direction multiplier method, and calculating a complementary evaluation system for the scheduling strategy. According to the invention, the comprehensive low-carbon index of the comprehensive energy system is utilized; the total carbon emission and the difference of regional carbon emission can be reduced at the same time during system scheduling; and by establishing a comprehensive energy system scheduling evaluation method, the complementary effect of the comprehensive energy system is evaluated from two perspectives of the whole and the unit, more comprehensive data support can be provided, and the influence of the complementarity of various energy sources in the comprehensive energy system on the comprehensive and regional carbon emission is scientifically evaluated.

Description

technical field [0001] The present invention relates to a technology in the field of electric power, in particular to a method and system for dispatching and evaluating an integrated energy system based on carbon emission management. Background technique [0002] In recent years, energy crisis and climate warming have received more and more attention. Natural gas is clean, efficient, and high-quality, and has been widely used as the main energy resource in some regions. Especially as an abundant clean energy, natural gas has developed into an important alternative energy source for energy saving and emission reduction in some areas. Some generator sets in the power system use natural gas as fuel, forming an integrated energy system that couples the natural gas network with the power network. The integrated energy system can coordinate and dispatch electricity and natural gas loads according to the operating conditions of the power network and natural gas network, and activ...

Problems solved by technology

[0003] The traditional integrated energy system cannot measure the carbon emissions of the system from the perspective of the system and the region, and the scheduling strategy cannot guarantee the effect of regional emission reduction

The traditional benefit evaluation of the integrated energy system only roughly involves the total carbon emission benefit of the system, and there is no evaluation method that can evaluate the multi-energy complementary effect of the integrated energy system dispatching strategy, nor does it evaluate the comprehensive energy from the two perspectives of the unit and the region. Carbon emissions of the system
