Low rating and individual characteristics of the Distributed Generators (DGs) make the standalone Micro
Grid (MG) weak power system. When the standalone MG contains wind generation system, special care
should be taken during the starting process of the wind generation system to avoid the MG instability.
This study proposes a new soft starting controller to improve the starting process of the wind generation
system. In the proposed controller, both the wind turbine blade pitch angle (mechanical) and the thyristor
switches firing angles (electrical) are coordinated, and controlled simultaneously. The coordination aims
to minimize and suppress the undesirable effects and consequences of the wind generation system
starting on the standalone MG performance. With employing the proposed hybrid and coordinated
controller, the wind generator starting current grows very slowly until it reaches its rated value. On the
other side, without employing the proposed controller, the wind generator starting current suddenly
jumps and exceeds 400% of its rated value. Also, without employing the proposed controller, the MG
frequency drops to less than 49.3 Hz. In addition, the voltage at MG buses drops to 0.9 p.u. in absence of
the proposed controller compared with 0.95 p.u. if the controller is employed. The novelty on the proposed
controller is the coordination between the thyristor valve firing angle (electronic) and the wind turbine
blade pitch angle (mechanical) to achieve the desired performance. The overall performance and the
power quality of the standaloneMGhave been highly improved after employing the proposed coordinated
hybrid soft starting controller.
