中文摘要:

观测生态系统的碳源/汇，可以有效构建碳循环过程进行二氧化碳的减排增汇。考虑到碳源/汇的观测有利于对碳的动态利用从而减少系统碳排放，为此提出一种计及碳源/汇作用下的综合能源系统日前优化调度策略。文章分析了综合能源系统中生态碳汇作用，提出碳捕获装置的模型，根据多能流耦合转换特性进行系统建模；从系统的碳源/汇作用设备分析出发，提出碳源控制和碳汇检测指标，依据指标确立相关调节费用；以降低总运行成本、降低碳排放、提高可再生能源利用水平为总体目标，提出基于粒子群改进算法求解优化调度方案；算例结果从经济效益与环境效益两方面进行对比分析，表明考虑碳源/汇作用设备的联合调度结果可以减少综合能源系统的碳排放，优化多能流耦合下不同类型供用能设备的运行，提升系统运行经济性与环保性。

英文摘要:

In an ecosystem, observing the behavior of its internal carbon sources and sinks can effectively construct a carbon cycle coefficient to reduce carbon dioxide emissions and increase sinks. Considering that the observation of carbon sources and sinks is conducive to the dynamic use of carbon to reduce system carbon emissions, for this reason, a day-ahead optimal dispatch strategy for integrated energy system analogous to the behavior of carbon sources and sinks is proposed. This paper analyzes the role of the ecological carbon sources and sinks function in the integrated energy system, puts forward the model of carbon capture device, and carries out the system modeling based on the coupling conversion characteristics of multi-energy flow. The carbon source control and carbon sink detection indicators are proposed, and the relevant adjustment costs are established according to the indicators. With the overall goal of reducing the total operating cost, reducing carbon emissions, and improving the utilization level of renewable energy, an optimal scheduling scheme based on an improved particle swarm algorithm is proposed. The results of the example are compared and analyzed from the aspects of economic and environmental benefits, and it shows that the joint scheduling results of carbon sources and sinks equipment can reduce the carbon emissions of the integrated energy system and optimize the operation of different types of energy supply and consumption equipment under the coupling of multi-energy flow, and improve system operation economy and environmental protection.
