Integrated energy system low-carbon scheduling method and system based on carbon transaction model

Abstract

The invention provides an integrated energy system low-carbon scheduling method and system based on a carbon transaction model. The method comprises the following steps: firstly, constructing an integrated energy system architecture integrating multiple renewable energy power generation and multiple energy forms of electricity, heat and gas; then, according to the price-type electricity-heat comprehensive demand response model and the carbon emission interval segmented carbon transaction cost model, constructing a comprehensive energy system double-layer scheduling model of which the upper layer takes the lowest user energy consumption cost and the lower layer takes the lowest outsourcing energy and carbon transaction cost as targets; and finally, solving the model by adopting a CPLEX solver to obtain a globally optimal solution. Based on the method, the invention also provides a comprehensive energy system low-carbon scheduling system based on the carbon transaction model, the problems of environmental pollution and energy shortage in the prior art are effectively solved, the operation economy of the system is improved, the carbon emission of the system is reduced, the consumption of renewable energy sources such as wind and light is promoted, and the method has the advantages of being scientific, reasonable, high in applicability, good in effect and the like.

Description

technical field [0001] The invention belongs to the technical field of low-carbon economic operation of an integrated energy system, and in particular relates to a low-carbon scheduling method and system for an integrated energy system based on a carbon trading model. Background technique [0002] The rapid economic development has brought enormous pressure to environmental protection, among which global warming caused by greenhouse gas emissions is an important issue facing the world. According to the survey, carbon dioxide emission is a key factor of climate warming, and electric power is a key industry of energy consumption in China, and its carbon dioxide emission accounts for about 50% of the country's total emission. Therefore, reducing carbon dioxide emission has become a priority of power system dispatching an important research hotspot. In this context, the integrated energy system (IES) integrates various energy forms such as electricity, heat, and gas at the same...

Problems solved by technology

[0003] In the existing technology, the carbon trading adopted for the dispatching problem of the IES low-carbon economy is mostly the traditional carbon trading with a fixed transaction price, and there are few thermal load demand responses that can be flexibly adjusted according to the thermal comfort demand changes of users in different periods. See the literature report and practical application of the IES scheduling method considering both step-wise carbon trading and integrated demand response coordination optimization, and taking into account the uncertainty of renewable energy generation
