Abstract

When a large-scale offshore wind farm (OWF) is connected to a power system, the power quality of the connected power system can be significantly deteriorated under various operating conditions and employed parameters. This paper presents the analyzed results of voltage variations and short-circuit ratio (SCR) of Taiwan Power System connected with a large-scale OWF of 100 MW using a commercial power-system simulation software. Ten ultra-high-voltage bus of onshore substations that are close to the potential OWF are properly selected as the connection points. The voltage variations and SCR results at the connection points under different lengths of submarine cable are accomplished and analyzed when the OWF is connected to the selected buses. The simulated results can offer a reference for the development of OWFs in Taiwan in the near future.
