Multi-period Dynamic Reconfiguration Method of Urban Integrated Energy System Topology Considering Flexible Supply and Demand Robust Balance

The conventional multi-period dynamic reconfiguration method of urban integrated energy system topology has the problem of low accuracy of reconfiguration results in the actual operation process, which is unable to determine the sustained reliability of the energy system after reconfiguration, leading to the reduction of system absorption rate and poor operation effect. The system topology is divided into multi-period dynamics based on reconfiguration effectiveness, and dynamic reconfiguration is completed according to the characteristics of multi-period dynamic reconfiguration of the distribution network. The comparative analysis shows that after the application of the new method, the system absorption rate has been significantly improved, which can improve the renewable energy absorption capacity of the urban comprehensive energy system.
