摘要

为降低风电功率预测误差对电氢综合能源系统调度经济性和准确性的影响,提出一种计及电氢联产系统的综合能源系统日内双层滚动优化调度方法。首先,考虑电制氢特性,在综合能源系统中应用电氢联产系统。其次,在日内调度中采用滚动优化方法,在滚动周期中,上层模型基于改进指数移动平均对电氢联产系统进行控制,并将区间预测作为控制约束,为综合能源系统提供稳定供电功率;日内下层模型依据上层结果确定周期内调度计划。最后,通过算例分析对比不同场景,结果表明,所提方法在降低风电功率预测误差对调度结果影响的同时实现系统经济性的提升。

Abstract

In order to reduce the impact of wind power prediction errors on the economics and accuracy of dispatch of electricity and hydrogen integrated energy systems, an intraday two-tier rolling optimal dispatch method for integrated energy systems that takes into account the electric-hydrogen cogeneration system is proposed. First, considering the characteristics of electricity hydrogen production, the electric-hydrogen cogeneration system is applied in the integrated energy system. Secondly, a rolling optimization method is adopted in intraday dispatch. In the rolling cycle, the upper level model controls the electricity and hydrogen cogeneration system based on the improved exponential moving average, and uses interval prediction as a control constraint to provide stable power supply for the integrated energy system; The intraday lower-level model determines the intra-period dispatch plan based on the upper-level results; Finally, different scenarios are compared through numerical examples. The results show that the proposed method can reduce the impact of wind power prediction errors on dispatch results while improving system economy.
