Grid Connection and Power Conditioning of Wind Farms

Wind power penetrations are increasing worldwide, and with these increasing penetrations come increasing worries about their impact on power systems operations. Wind interconnection studies are a very important step for maintaining grid reliability, stability, and power quality. The behavior of a wind plant during dynamic events is an important consideration in that it can impact the rest of the system, potentially compounding contingency event impacts with a suboptimal response. The response of a wind turbine to such an event is strongly influenced by the generator type, and each turbine type has different requirements in terms of low voltage ride through, reactive power requirements, and frequency control. Additional measures may also be taken to protect the generator in the case of an event, while still providing necessary services to the grid.
