摘要：
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,relia-bility 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. © 2019, Electric Power Automation Equipment Press.
