    摘要:

    电—气互联综合能源系统得益于天然气的高比例应用与电转气(P2G)的吸碳能力、能量转移特性,成为新兴的消纳弃风、低碳排放平台。在此背景下,提出一种含P2G弃风启停的电—气互联综合能源系统消纳弃风、低碳运行模型,以机组运行成本最小、弃风量最小、碳排放量最小为目标,同时引入电转气弃风启停与碳交易市场,使系统兼顾碳排放目标与消纳弃风目标的同时更具实际效益。利用MATLAB中的YALMIP工具箱调用CPLEX求解器进行求解,分别在3个不同场景下进行仿真计算,仿真结果验证该模型具有良好的消纳弃风能力,可以大量减少碳排放。最后,比较P2G有启停与无启停下的碳排放量与经济效益,得出P2G在碳交易价格较高时应设置弃风启停,以避免P2G在日间无弃风时运行使碳排放增加。

    Abstract:

    Benefit from the high proportion of natural gas application and the carbon absorption capacity a of P2G (power to gas, P2G), the integrated energy system has become an emerging platform for wind accommodation and low-carbon emissions.This paper presents a low-carbon operation dispatch model for integrated electrical-gas energy systems considering wind power curtailment.The minimum operation cost of power unit, wind power curtailment and carbon emissions are chosen as the objective. Meanwhile,the concept of P2G start-stop of wind curtailment and carbon trading market is introduced to enable the system accommodate more wind power and reduce carbon emissions.This model is solved by the multi-objective particle CPLEX solver from the YALMIP toolbox and simulated under 3 different scenarios to verify that the proposed model has the ability to absorb the redundant wind power and significantly reduce carbon emissions. Finally, carbon emissions and economic benefits of P2G with/without wind curtailment start-stop device are compared. It is shown that system operator should set wind curtailment start-stop device if the carbon trading price is high so as to avoid carbon emission increasing from P2G during daytime when there is no wind curtailment.
