Abstract

The invention discloses an integrated energy system optimization scheduling method considering a carbon trading mechanism and a flexible load. The technical solution of the invention comprises a stepof modeling a coupling link of an integrated energy system based on an energy center model and outputting electric energy, heat energy and natural gas to supply load demand, wherein input energies areelectric energy and natural gas, a step of introducing the carbon trading mechanism into an integrated energy system scheduling model, comprehensively considering the carbon emissions of an entire energy supply chain, and establishing an over-discharge penalty mechanism, a step of applying the flexible load to the low-carbon economic operation of the integrated energy system, and a step of introducing a power system network constraint, a natural gas system network constraint and an energy center internal constraint on the above basis and establishing an integrated energy system low-carbon economic scheduling model with the goal of carbon trading cost, flexible load scheduling cost and system energy cost. According to the method, the consumption of renewable energy can be promoted, the system energy consumption and carbon emission are reduced, and the comprehensive benefits of the system are significantly improved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an optimal scheduling method for an integrated energy system considering a carbon trading mechanism and flexible loads. Background technique [0002] With the continuous development of my country's economy and society, the energy situation and environmental pollution are becoming more and more serious. As an inevitable choice to solve energy crisis and environmental problems, the integrated energy system with multi-energy complementarity has become the focus of attention from all walks of life. The integrated energy system breaks the existing mode of separate planning and independent operation of various energy sources, and can realize the coordinated optimization and mutual benefit of various energy sources. [0003] At present, the carbon trading mechanism is considered to be one of the most effective energy-saving and emission-reduction measures. So far, many studies have introdu...
