Simulation research of a novel wind and solar hybrid power system

The phase windings of open-winding permanent magnet machine are separated, one side of the open-winding permanent magnetic machine was connected to the rectifier for the DC output voltage, the other side was connected to the inverter for the regulation of the output voltage. The proposed machine has the prominent advantages of high reliability due to the elimination of the mutual influence, and it can be used in the novel wind and solar hybrid power system with the advantages of system structure simplification and control modules reduction compared to the traditional wind and solar hybrid system. The simulation model of the proposed system which is composed of wind turbine with fixed pitch, open-winding permanent magnet machine and control model for the maximize power point tracking(MPPT) of the turbine, was built by Matlab/simulink. Dynamic and steady-state characteristics of the hybrid power system with the wind power tracking algorithms were given to demonstrate the feasibility of the proposed wind power tracking algorithm. Simulation results show the validity of the modeling and control strategy of the proposed system.
