A Vulnerability Assessment Method for Urban Utility Gallery Integrated Energy System

Abstract

The invention discloses a vulnerability assessment method for an integrated energy system of an urban utility tunnel, comprising: S1, establishing a vulnerability assessment model of the integrated energy system of an urban utility tunnel by combining the integrated utility tunnel and the integrated energy system and their correlation; S2. Collect the actual energy demand, attack cost and protection cost of each energy demand node in the integrated energy system in real time, and input them into the vulnerability assessment model of the urban utility tunnel integrated energy system to obtain the vulnerability of the urban utility tunnel integrated energy system. evaluation result. The vulnerability assessment model of the urban utility tunnel integrated energy system established by combining the integrated utility tunnel and the integrated energy system, and considering the geographical relationship between the utility tunnel and the integrated energy system, is highly accurate. In addition, the method provided by the present invention can accurately solve the optimal protection strategy of the integrated energy system of the urban utility tunnel under the deliberate attack, help the city manager to make the optimal protection decision under the limited cost, and reduce the loss of the system.

Description

technical field [0001] The invention belongs to the field of critical infrastructure resilience, and more specifically, relates to a vulnerability assessment method of an urban utility corridor comprehensive energy system. Background technique [0002] The comprehensive pipe gallery is an underground comprehensive corridor of urban pipelines, that is, to build a tunnel space underground in the city, to concentrate various engineering pipelines in this space, and to implement unified planning, unified design, unified construction and unified management, which is the guarantee of urban operation. Critical infrastructure and lifeline. Today, integrated pipe corridors are widely constructed in many modern cities. However, the construction of comprehensive utility corridors has brought new threats. The network of urban comprehensive utility corridors is the carrier of urban comprehensive energy systems. Since comprehensive utility corridors increase the geographical interdepende...
