摘要

为降低光伏功率波动对调度准确性的影响，提出一种考虑动态平滑周期的多时间尺度综合能源系统双层滚动优化调度策略，提升系统运行的经济性与环保性。首先，将指数移动平均用于光伏功率平滑，并基于该方法提出针对电-热-氢综合能源系统的改进平滑方法；其次，构建日内双层滚动优化调度策略，在日前调度的基础上，在日内上层优化模型中使用考虑动态平滑周期的改进平滑方法来确定绿氢系统中的控制器平滑次数与平滑周期，将光伏发电功率低波动成分输入综合能源系统，将光伏发电功率剧烈波动成分电解水制氢供燃料电池汽车使用，然后由下层调度确定具体日内调度计划；最后，算例分析针对上层平滑方法设置不同场景进对比，结果表明，所提出的考虑动态平滑周期的双层滚动优化调度策略与其他调度策略相比均有一定的经济性与环保性的提升，具有更强的适应性与灵活性。

Abstract

In order to reduce the impact of PV power fluctuations on scheduling accuracy

a two-layer rolling optimal scheduling strategy for integrated energy systems with multiple time scales considering dynamic smoothing cycles is proposed to improve the economy and environmental friendliness of system operation. First

exponential moving average is used for PV power smoothing

and an improved smoothing method is proposed based on this method for the electricity-heat-hydrogen integrated energy system; second

an intraday two-layer rolling optimal scheduling strategy is constructed

and on the basis of the day-ahead scheduling

an improved smoothing method that takes into account dynamic smoothing periods is used in the intraday upper optimization model to determine the number of controller smoothing times and smoothing periods in the green-hydrogen system

and the low fluctuation component of PV power is inputted into the integrated energy system. The low fluctuation component of PV power is inputted into the integrated energy system

and the highly fluctuating component of PV power is electrolyzed to produce hydrogen for fuel cell vehicles

and then the lower level scheduling determines the specific intraday scheduling plan; finally

the example analysis is performed for the comparison of different scenarios for the setting of the upper level smoothing method

and the results show that the proposed two-layer rolling optimization scheduling strategy considering the dynamic interval has a certain economic and environmental performance improvement compared with other scheduling strategies. The results show that the proposed two-tier rolling optimisation scheduling strategy considering dynamic time interval has certain economic and environmental improvement compared with other scheduling strategies

and has stronger adaptability and flexibility.
