Abstract :
This paper deals with a DC-micro grid in an isolated island. The proposed method is composed of gearless wind power generation system, battery, and DC loads in DC distribution system. The battery can avoid DC over-voltages by absorbing the PMSG power during line-fault. In addition, the control schemes in this paper include the maximum power point tracking (MPPT) control and a pitch angle control for the gearless wind turbine generator. By means of the proposed method, high-reliable power can be supplied to DC distribution system during line-fault, and stable power supply from PMSG to the electrical power system after line-fault clearing can be achieved. The effectiveness of the proposed method is performed in a MATLAB/Simulink Rreg environment.
