In the case of operating in a very weak grid system, when wind generation becomes a significant portion of the power system or maybe the only energy supply, the wind power generators and converters are expected to help maintain the grid voltage. The terminal (grid) region convertor desires to vocation as an electrical energy source to assist control the terminal (grid) voltage amplitude and rate of recurrence by regulate the reactive control and active power flow, severally. For a direct-drive magnet synchronous generator through a full power convertor, the active power must be provided by the captured wind generation. The active power flow between the supply (captured wind power) and therefore the grid (load) should be balanced by actively controlling the generator speed and turbine pitch angle. In the study, the coordinated control of generator speed and blade pitch angle is planned along with a dc-link voltage controller. A model of the grid-side tool prepared as a voltage give for design and also the strategy relating to voltage and frequency regulation is given. Simulation is administered with totally different wind and cargo profile. The results show the wind energy will facilitate support the weak grid and power the native grid in complete mode still.
