考虑容灾性能的综合能源系统弹性提升策略研究
Research on strategy for enhancing the resilience of integrated energy system considering disaster tolerance performance
摘要
Abstract
Proactive preparation is a key condition for energy systems to respond to disaster events.Against this research background,this paper proposes an active method to enhance the resilience of integrated energy system by obtaining pre-disaster optimal scheduling strategies.Firstly,the paper analyzes the mathematical model of typhoon disasters,calculates the fault model of overhead lines within the system,and conducts fixed-point reinforcement based on the line failure rate.Then,the total storage capacity of electricity,heat,and natural gas within the dis-patch range from the first impact of the disaster to the worst-case scenario is defined as the preparedness index.To improve the readiness index,the cost of load reduction in the pre-disaster scheduling range is needed.Therefore,the paper constructs a Markov model of the integrated energy system,and adopts Actor-Critic algorithm to solve the optimal scheduling strategy of the system in disaster,which solves the multi-objective optimization problem between the readiness index and the load supply.Finally,through simulation verification,the optimized scheduling strategy can significantly improve the readiness index and resilience index of the system,and significantly reduce post disas-ter load losses.关键词
