A carbon source / sink evaluation index system of the system is put forward, corresponding excitation factors are determined on the basis of the index system, adjustment cost is calculated, a comprehensive energy system low-carbon scheduling model is put forward accordingly, and an optimal strategy is obtained through deep learning output prediction and DDPG algorithm training. According to the method provided by the invention, the carbon emission in the comprehensive energy system and the capturing and recycling process are subdivided, so that the influence caused by carbon reduction is reduced while the carbon emission of the system is reduced, and the environmental protection benefit and the economic benefit are improved and maintained. The method can be widely applied to low-carbon scheduling of an integrated energy system.

Description

technical field [0001] The invention relates to the field of integrated energy system scheduling, in particular to an integrated energy system optimization scheduling method that takes into account the role of carbon sources and sinks. Background technique [0002] With the rapid development of social economy, human beings' demand for energy is increasing day by day, and energy shortage and environmental problems have also arisen from this.

Problems solved by technology

However, the above-mentioned studies on the day-ahead optimal scheduling of the integrated energy system only focus on the total carbon emissions emitted by the system to the outside world, while ignoring the different roles of the equipment participating in the carbon flow of the system under the multi-objective operation of the system. In the process of system carbon emission and carbon capture and reuse, there are energy conversion and energy complementarity, so related equipment can also participate in the system's consumption of new energy
