INTEGRATED ENERGY SYSTEM ICE MELTING AND REPAIR SCHEDULING STRATEGY CONSIDERING EMERGENCY POWER VEHICLES

针对含高比例可再生能源的综合能源系统遇到冰灾等灾害时由于除冰抢修导致失负荷量较大的问题,提出考虑应急电源车的综合能源系统融冰与抢修调度策略。首先,根据气象数据分析输电线路覆冰增长过程物理特性,从雨凇、雾凇覆冰角度建立覆冰增长计算表达式。其次,上层优化利用抢修小队在电网冰灾时为电网快速恢复供电,下层优化模型利用综合能源系统与应急电源车进行优化,采用抹香鲸算法对模型进行求解。采用IEEE33节点系统进行仿真,算例结果表明基于该文方法可提高综合能源系统优化调度的效率,并保证电网的安全稳定运行。

Aiming at the problem of large load loss caused by ice disaster and other disasters in the integrated energy system with high proportion of renewable energy due to de-icing and emergency repair,an integrated energy system de-icing and emergency repair scheduling strategy considering emergency power supply vehicles is proposed.Firstly,according to the meteorological data,the physical characteristics of the icing growth process of transmission lines are analyzed,and the calculation expression of icing growth is established from the perspective of rime and rime icing.Secondly,the upper level optimization is to use the emergency repair team to quickly restore the power supply for the power grid during the ice disaster.The lower level optimization model is optimized for the integrated energy system and the emergency power supply vehicle,and the model is solved by the sperm whale algorithm.The IEEE 33 node is used to simulate the ice melting decision.The results show that the method based on this paper can improve the efficiency of the optimal scheduling of the integrated energy system and ensure the safe and stable operation of the power grid.
