Short-Term Energy Cache Regulation for Energy Router: A Robust H-Infinity Approach

With the development and evolution of power system, the penetration of renewable energy increases continuously. The energy Internet is proposed as the future of conventional power systems, and it ensures the utilization efficiency of renewable energy sources and promises more reliable and intelligent energy services. Being able to transmit and cache energy-information flows among microgrids, energy routers play the key role in the construction of future energy Internet. It is important to ensure the stability of the core energy transmission functionalities of energy routers. In this paper, the short-term energy cache regulation for energy routers is investigated. A robust control method against the potential uncertainties in energy transmission processes is proposed. The energy cache regulation efficacy of the proposed control method is evaluated with numerical simulation. The results demonstrate the feasibility and effectiveness of the proposed method.
