A New Five-Port Energy Router Structure and Common Bus Voltage Stabilization Control Strategy

Multi-port energy routers are a core device that integrates distributed sources and enables energy-to-energy interconnections. For the routing system, construction of its topology, establishment internal model switching control common bus voltage stability key elements research. In this paper, five-port router structure is proposed, including PV port, an storage grid-connected DC load AC port. Among them, port involve bidirectional flow, which ports control. system state, strategy proposed based on topology flow direction. When external conditions change, can be stabilized by means quick response from saturated, state switched, works to achieve stability. The rapid stabilization free achieved combining fast predictive with properties multiple switching. Finally, feasibility verified building simulations in MATLAB.
