SSCI analysis: Assessment of Interactions Involving Wind Farm Systems

<p>This presentation provides an overview of recently proposed generic EMTP wind turbine models, which have been validated against field measurements, and a benchmark study system for the assessment of low-frequency interactions involving wind farms in radial series-compensated grids. Based on these models, detailed EMTP results are presented and modal analysis is applied to help explaining some of the identified issues and provide mitigation. Finally, a recently proposed Abstract : Recently, field events involving adverse interaction between grid-connected inverters and the existing power infrastructure have been reported. Hence, the ever increasing integration of such devices is yielding the need for detailed EMT-Type models to better understand such phenomena, as well as reliable screening methodologies for the efficient identification of potentially critical scenarios during new interconnection processes. This work provides an overview of recently proposed generic EMTP wind turbine models, which have been validated against field measurements, and a benchmark study system for the assessment of low-frequency interactions (sub-synchronous control interaction) involving wind farms in radial series-compensated grids. Based on these models, detailed EMTP results are presented and modal analysis is applied to help explaining some of the identified issues and provide mitigation. Finally, a recently proposed methodology aiming at the efficient identification of critical scenarios, namely, the DQ-Scanning technique, is outlined and its effectiveness demonstrated by its application to the aforementioned systems.
