Integrated Energy System Resilience Assessment Based on Load Shedding Methodology

Abstract

With the increasing awareness of environmental protection, integrated energy systems have gained an increasingly attention. However, the significance of resilience of integrated energy systems has been increasingly emphasized at a time when extreme events occur frequently. Therefore, this paper focuses on the concept of resilience. Firstly, the resilience evaluation index of integrated energy system is established. The index considers the damage frequency of each device in the system, the scale of load loss caused by failure and the time of the disaster. Subsequently, this paper gives the resilience evaluation process based on the simulation of the load loss of the system in a disaster. By improving the enumeration method, the accuracy of the overall resilience assessment when enumerating low-order cases is improved. The effectiveness of this method is tested in an actual case. Finally, this paper proposes a specific process for resilience strengthening of the system using this resilience assessment method and verifies that these methods can effectively improve the system resilience.
