| Abstract: |
| Integrated energy system positively contributes to the improved energy utilization efficiency, multi-energy complement, and the construction of a low-carbon sustainable energy system. However, it is notable that the deep interdependency among multiple energy systems creates significant operational risks. As such, the research on security analysis and optimal control of electricity-gas integrated energy system is reviewed. The steady-state and transient energy flow models of electricity-gas integrated energy system are introduced, which includes the exact nonlinear, linear, and convex models. Then, the security analysis of electricity-gas integrated energy system is introduced, in which the state estimation, security assessment, reliability analysis, and resilience analysis are discussed. Subsequently, the optimal control model of electricity-gas integrated energy system is introduced, in which the multi-period optimal preventive and corrective models are proposed. Finally, the promising research directions on security analysis and optimal control of electricity-gas integrated energy system are summarized. |
