摘要
为建立一个清洁低碳、安全稳定的能源系统,提出了基于绿证-碳交易机制的氢能利用综合能源系统多时间尺度优化调度策略。首先,为发挥氢能高效清洁的作用,建立电解槽热氢联产模型。其次,为降低系统的碳排放量,分别构建绿色证书交易机制和奖惩阶梯型碳交易机制。最后,为降低源-荷预测误差对系统运行的影响,构建基于模型预测方法的日前-日内-实时多时间尺度的优化调度模型。算例分析表明,所提模型能有效降低碳排放量和系统功率波动,提高系统的稳定性和经济性。
To establish a clean,low-carbon,safe and stable energy system,a multi-timescale optimal scheduling strate⁃gy for an integrated energy system for hydrogen utilization is proposed based on the green certificate-carbon trading mechanism.First,an electrolyzer hot-hydrogen co-production model is established to give full play to the efficient and clean role of hydrogen energy.Second,to reduce the carbon emission of the system,a green certificate trading mecha⁃nism and a reward and punishment ladder-type carbon trading mechanism are constructed respectively.Finally,a mod⁃el predictive control-based day-ahead-intraday-realtime multi-timescale optimal scheduling model is established to re⁃duce the influence of source-load prediction errors on system operation.The analysis result of an example shows that the proposed model can effectively reduce the system’s carbon emissions and power fluctuations,thus improving its stabili⁃ty and economy.
