A Novel Power System Topology of Grid-Connected PV-Wind Hybrid System Using New Multiport Nine-Switch Converter

In this paper, the new configuration for hybrid photovoltaic (PV)/wind power generation system is proposed in order to improve the power system operation. The proposed power topology is based on the new nine-switch multiport converter and all energy sources are connected in parallel to a common DC link. The output characteristics of wind turbine driven by permanent magnet synchronous generator (PMSG), PV module and battery storage are presented. In order to achieve the maximum power point tracking (MPPT) for input sources the perturbation and observation algorithm is employed. Also, the operational principle of the new nine switch multiport converter is detailed. The proposed configuration can be connected to grid and load (BTS Station) simultaneously and it is the main feature of this topology. Eventually, provided simulation results confirm the feasibility and effectiveness of the suggested hybrid system topology.
