摘  要:综合能源系统面临自然灾害、网络攻击等突发情况时,存在子系统故障导致连锁故障的安全问题。可再生能源的大量接入,也给系统安全运行带来挑战。为此,提出考虑能源禀赋和用户需求的最优负荷削减算法和综合能源系统一体化仿真模型,帮助系统在紧急情况下快速反应以保证能源供应。建立综合能源系统韧性评估指标体系,评估系统切除负荷后的运行情况。采用强化学习的思想建立集中式风光发电的等值功率模型,将预测功率代入高压输电网的算例进行分析,得到考虑集中式风光发电的负荷切除策略和评估指标。结果表明集中式新能源的接入可以有效提升区域综合能源系统的韧性。Integrated energy systems face security issues when faced with unexpected situations such as natural disasters and cyber attacks,where sub-system failures lead to chain failures.The massive access to renewable energy sources also poses challenges to the safe operation of the system.An optimal load shedding algorithm that considers energy endowment and user demand and an integrated simulation model of the integrated energy system are proposed to help the system react quickly in emergency situations to ensure energy supply.An integrated energy system resilience assessment index system is established to assess the operation of the system after load removal.An equivalent output model for centralised landscape power generation was established using reinforcement learning ideas,and the predicted output was substituted into the calculation example for analysis to obtain load shedding strategies and operational indicators considering centralised landscape power generation.The results show that the access of centralised new energy can effectively improve the resilience of the regional integrated energy system.
