Voltage and frequency profile analysis of electricity networks with wind energy integration

Wind energy conversion systems (WECSs) are currently the most matured and preferred as bulk renewable energy generation systems across the world. Hence extensive research is being done on investigating the impact of wind energy integration on voltage and frequency of electricity networks for proper planning of their grid-integration such that network performance is not deteriorated, rather enhanced in terms of power quality and stability. This paper presents explores through modeling and simulation in DIgSILENT Powerfactory, how wind power plant technology, capacity and point of integration affect the voltage profile and frequency profile of utility power grid. Ensuring enhanced power quality in electricity networks is important particularly in the current wind energy deployment in South Africa.
