摘要
Multi-energy integration system is increasingly becoming one of the effective solutions to the problems of energy shortage and irrational use. The energy hub with energy router is a kind of minimum typical structure of the multi-energy fusion system. Rational energy management of energies accessed to its ports help achieve high-efficiency and economical operation. First, this paper set basic operation strategies of energy router, analyzing energy balance equations of the energy hub and operation constraints of accessed equipment based on the basic operation strategies. Then the energy storage virtual queue was constructed based on Lyapunov optimization method which converters the time-coupled energy storage constraints into virtual queue stability, and the flexible loads virtual queue were constructed. Finally, Lyapunov-drift-penalty function was constructed to simplify the energy management problem achieving the goal of reducing operating costs by control decisions given according real-time operating state. The MATLAB programming algorithm was used to verify the effectiveness of the proposed energy management strategy. © 2019 Chin. Soc. for Elec. Eng.
