Coordinated Optimization of Electricity-Gas Integrated Energy System

Abstract

This paper proposes a coordinated optimal dispatch model for the electricity-gas integrated energy system considering multiple reserve resources. The model takes into account the reserve resources including generator reserve capacity, energy storage equipment and interruptible load, and considers the transmission capacity of the reserve capacity in the electricity and natural gas network in the face of emergencies to ensure the safety and reliability of system operation. The simulation results confirm that the coordinated optimal scheduling model of the electricity-gas integrated energy system with multiple reserve resources proposed in this paper can reduce the total operating cost of the system and improve the flexibility of system operation.
