Abstract
Exponential growth of photovoltaic systems connected to the grid has been observed over the last decade in Brazil concurrently with concerns about the power quality and operational compliance of related equipment. In the past decades, there has been much research and debate regarding the definition of electromagnetic compatibility requirements. Since Brazil has both government and private entities responsible for the product certification and homologation process, it is important to discuss and analyze these entities’ roles from an electromagnetic compatibility viewpoint in photovoltaic systems connected to the network. Thus, it is our aim to amplify current discussions on the Brazilian scenario. This work provides, first, an analysis of the origin and propagation of conducted and radiated electromagnetic interference in grid-connected photovoltaic systems, highlighting such concepts as symmetrical and asymmetrical noise and unintended antenna effects. Finally, the standardization framework is investigated based on the Brazilian scenario and current standards.
