Impact of a 47 MVA Aeroderivative Gas Turbine Generator on a 346 MW Bulk Wind Farm - Case Study on Voltage & Frequency Response

This paper demonstrates the impact of a single GE LM2500XPRESS* Aeroderivative gas turbine generator (GTG), when operated in parallel with a bulk wind power plant, with regards to the latter's power transfer capacity, by providing the necessary voltage and reactive power support at the point of interconnection (POI). The hybrid application also improves the transient voltage response during large disturbances at the POI. It further demonstrates the GTG's positive impact on the network frequency profile during short-term load adjustment and loss of generation events.
