Comprehensive energy system peak clipping and valley filling scheduling strategy based on paid distribution

Abstract

The invention relates to an integrated energy system peak clipping and valley filling scheduling strategy based on paid distribution, and belongs to the technical field of power-gas integrated energy system optimization scheduling, and the strategy comprises the steps: obtaining a first initial parameter, a second initial parameter and a third initial parameter; respectively constructing a first optimization model, a second optimization model and a third optimization model; according to the three established optimization models, constructing a total cost objective function by using an equal weight method, linearizing the total cost objective function, and solving by taking the minimum total cost as an optimization objective to obtain an optimal solution of a decision variable; the decision variables comprise an energy purchasing strategy of the system from a superior energy network, output of energy conversion equipment and a scheduling strategy of peak clipping and valley filling equipment; and respectively substituting the solved corresponding decision variables into the first optimization model, the second optimization model and the third optimization model to obtain corresponding results. The optimization scheduling model comprehensively considers the stability, the economical efficiency and the low-carbon environmental protection property of the operation of the energy system.

Description

Technical field [0001] The present invention involves a comprehensive energy system peak-filled grade scheduling strategy based on paid distribution, which belongs to the field of optimization and scheduling technology of electric-gas comprehensive energy systems. Background technique [0002] At present, with the continuous advancement of market reform and the rapid development of information technology, only the traditional monopoly energy supply system that the power company meets the corresponding energy needs of users is gradually being replaced by the comprehensive energy system. The comprehensive energy system can give full play to the advantages complementarity between various forms of energy, effectively improve the flexibility of energy supply, and play an important role in the context of people's continuous improvement of energy demand and quality. [0003] Comprehensive energy systems will inevitably produce carbon dioxide during the process of purchasing energy and e...
