Development of Control System for Grid Integration of Wind Generation System
This paper presents simulation results of a control scheme of a variable-speed wind turbine with a permanent magnetic synchronous generator (PMSG) integration into the utility grid. The problem of integration of wind is that it relies heavily on weather conditions and air speed. So, there is a necessity for developing control techniques for grid integration wind system including a method for voltage and current control that stabilises the voltage and current. The effectiveness of the PI controller in the system under different of weather and conditions is studied. A pitch angle controller module with PI control is developed in this work that is suitable for wind power conversion system. Then, the system behaviour and performance are studied. The system stability is also considered when there is a change in pitch angle or a fault in the system. This paper advocates that the proposed PI controller gives a good performance.
