摘要：

An IES(Integrated Energy System) formed by integrating and optimizing multiple energy systems provides a new solution to energy and environmental problems. The type and capacity of components in an EH(Energy Hub), which is the coupling link among multiple energy systems, play an important role in the secure and economic operation of IES. In this context, considering N-1 security criterion, an optimal placement model of EH for IES involved with electric power system, natural gas system and thermal load is proposed. Firstly, on the basis of the EH framework, the energy coupling part of an IES is modelled. Then, with the minimization of the annual comprehensive cost as the optimization objective, a mixed-integer se-cond order cone programming model for the optimal placement problem of EHs is established with the energy coupling constraints, electric power system operation constraints, natural gas system operation constraints together with N-1 security constraints of the electric power system all taken into account, and then solved by the YALMIP/GUROBI commercial solver. Finally, an IES example is employed to demonstrate the presented optimization model and solution method. © 2019, Electric Power Automation Equipment Press. All right reserved.
