Impact of series active voltage conditioners on modernized grid

Series Active Voltage Conditioner (AVC) is the state of the art in voltage regulation and conditioning. A new method to model the AVC is developed in this paper. The paper also discusses the envisaged impact on grid-tied renewable energy sources and the associated impact of equivalent grid stiffness is examined. Grid behavior due to AVC operation during overvoltages and undervoltages is studied and impact on tied Wind Turbine Generators and Photovoltaic systems is discussed.
