Important Considerations in Development of PV Inverter Models for High Frequency Emission (Supraharmonic) Studies

Conference Paper


Abstract


  • In addition to the low order harmonics, power electronic systems tend to emit high frequency emissions (HF) in the range of 2-150 kHz where photovoltaic (PV) inverters play an important role. The recent high penetration of PV inverters in electricity distribution networks has necessitated the development of PV inverter models suitable for HF studies. Some of the major concerns associated with this work include selecting a suitable modelling approach, building experimental setups and achieving a compromise between the simplicity and the accuracy of the model. Based on research undertaken using commercially available single-phase PV inverters, this paper presents in detail how the aforementioned concerns can be handled to develop inverter models that are suitable for HF emission studies.
