摘要
针对极端灾害下电-热综合能源系统的韧性难以准确量化的挑战,提出了一种台风灾害下的电-热综合能源系统韧性评估方法。构建了典型台风灾害下的元件故障概率模型,基于蒙特卡罗方法确立了典型故障的场景。针对韧性的三大核心特征建立了面向电-热综合能源系统的分时段评估体系,通过所设3个一级指标及6个二级指标实现了对系统韧性的多层次、多角度评估。结合IEEE39节点系统及巴厘岛32节点系统构建了电-热综合能源系统,实现了对所提评估指标的验证。仿真结果表明,相比于独立电热系统,考虑热网双重惯性的电-热综合能源系统在灾害环境下的运行水平更高、负荷损失更小,具有更高的韧性水平。
To address the challenge of accurately quantifying the resilience of integrated electricity and district heating system under extreme disaster,a assessment method for integrated electricity and district heating system under typhoon disaster is proposed.A component failure probability model under typical typhoon disaster is constructed,and typical failure scenarios are established using the Monte Carlo method.A timebased assessment system for integrated electricity and district heating system is established based on the three core features of resilience.The system includes three primary indicators and six secondary indicators,enabling the multi-level and multi-angle evaluation of the system’s resilience.Simulations are carried out using the IEEE 39-bus system and the Bali Island 32-bus system to validate the proposed assessment indicators.The simulative results show that,compared to independent electricity and thermal systems,the integrated electricity and district heating system considering the dual inertia of the thermal network operates at a higher level and experiences smaller load losses under disaster conditions,demonstrating greater resilience.
