Photovoltaic systems continue to be deployed at increasing levels and their impact on the electric grid needs to be evaluated more accurately. This includes the impact both in the local grid where they are connected and the impact on the operation of the whole system. As a consequence, adequate models of panels, inverters, and the rest of the grid are required. Models of photovoltaic systems need to characterize their dominant characteristics and effects on the electric grid for the different types of studies, i.e. load flow, harmonic distortion, voltage stability and electromagnetic transient studies. This paper gives an overview of models that are currently in use for different types of grid impact studies, and points to their applications and limitations.
