Study of 5 MW grid connected PMSG wind turbine under voltage dip: Case study

The study and simulation presented in this article provide a comprehensive analysis of the dynamic and control performance of a wind turbine connected to the electrical network during a voltage dip. The wind turbine setup utilizes a Permanent Magnet Synchronous Generator (PMSG) with the goal of optimizing the power output from the variable speed wind system in these circumstances. The suggested control approach employs a converter on the generator side to regulate the DC bus voltage, and a converter on the network side to manage the active and reactive power flows into the grid. This approach aims to provide a good regulation of the DC bus voltage despite any disturbances caused by the drive train and to satisfy the requirements for active and reactive powers necessary to achieve optimal operation of the wind conversion system. The network side converter plays a crucial role in managing the power injection into the electrical network. During a voltage dip, it can be used to control the active and reactive powers injected into the network, thus reducing the effects of the voltage dip on the system. Additionally, the control strategy also takes into account the need to ensure that the system is operating at its most efficient state, and the active and reactive powers are optimized to meet this requirement.
