考虑碳排放惩罚因子的综合能源系统优化规划

Optimal planning of integrated energy system considering carbon emission penalty factor

能源行业在碳排放中所占比重较大,是节能减排的主力军,为保证系统的可持续发展,有必要将碳排放考虑到综合能源系统规划。为此建立一种考虑碳排放惩罚因子的综合能源系统规划模型,首先,针对某园区的热、电负荷特征,提出4种规划方案,以净现成本最小为优化目标得到4种规划方案在考虑碳排放惩罚因子场景下的最优容量配置;其次,从经济效益与环境效益两方面对比分析4种规划方案优劣势,并分析综合能源系统的热电供需平衡;最后,针对碳排放惩罚因子进行灵敏度分析。结果表明,考虑碳排放惩罚因子可以减少综合能源系统的碳排放,且可再生能源、储能装置以及燃气轮机都可以减少碳排放,提升环境效益。

The energy industry accounts for a large proportion of carbon emissions and it is the main force of energy conservation and emission reduction. In order to ensure the sustainable development of the system, it is necessary to take carbon emissions into account when planning the integrated energy system. Under the backgound, an integrated energy system planning model is established in this paper considering carbon emission penalty factor. Firstly, according to the thermal and electrical load characteristics of a park, four planning schemes are proposed in this paper. The minimum net present cost is chosen as the optimization objective, the optimal capacity allocation of four planning schemes under the scenario of whether carbon emission penalty factor is considered or not. Secondly, the advantages and disadvantages of the four planning schemes are compared from the aspects of economic benefit and environmental benefit, and the thermoelectric coupling relationship of the integrated energy system is analyzed. Finally, the sensitivity of carbon emission penalty factors is analyzed. The results show that the carbon emission penalty factor can reduce the carbon emission of the integrated energy system, and the renewable energy, energy storage equipment and gas turbine can reduce the carbon emission and improve the environmental benefits.
