A method for restoration and improvement of electric-gas integrated energy system

Abstract

The invention discloses a recovery and improvement method for an electric-electrical integrated energy system. Establish the network structure topology model of the electric-gas integrated energy system; determine the initial system operating state under the network structure topology model of the electric-gas integrated energy system; establish the restoration sequence optimization model of the electric-gas integrated energy system; The recovery power parameters of the gas integrated energy system can be obtained to obtain the recovery status of the electric-gas integrated energy system, and judge and implement improvements based on the recovery status. The invention can obtain the restoration sequence of power lines and natural gas pipelines after a large-scale failure of the electric-gas integrated energy system, instruct system construction personnel to repair the power lines and natural gas pipelines according to the obtained restoration sequence, and quickly restore the power load and natural gas load in the system. , thereby effectively improving the overall resilience of the electrical-electrical integrated energy system.

Description

technical field [0001] The invention belongs to an electric-gas integrated energy system restoration and optimization method belonging to the technical field of electric power systems and integrated energy systems, and relates to a recovery capability evaluation and improvement method of an electric-gas integrated energy system under the condition of deep coupling between an electric power system and a natural gas system. Background technique [0002] In recent years, the installed capacity of gas turbines has continued to increase, and the power generation of gas turbines accounts for a large proportion of the total power generation of the power system, resulting in the operation of the power system being more dependent on the natural gas system. At the same time, with the introduction of power-to-gas equipment, the gas production of the natural gas system gradually depends on the power load of the power system. However, the interdependent nature of the power system and the...
