Abstract
With the rapid increase in renewable energy integration in the electric grid, grid codes around the world are getting updated with requirements of grid support functions (GSFs) for the distributed energy resources (DERs). The Canadian interconnection standard CSA C22.3 No. 9 recently underwent revision and recently completed the public review process. This revised standard included advanced GSFs for DER systems and the test procedures (mostly referring to IEEE 1547.1 or UL 1741 SA) for assessing these DER GSFs. Two commercial solar/photovoltaic (PV) smart inverters were tested at the CanmetENERGY inverter test facility following the test procedures from UL 1741 SA and using the parameters from CSA C22.3 No.9. This paper presents the important aspects of the test procedure while doing standard compliance tests for the selected GSFs. Test results, issues requiring future consideration and comments are presented in this paper.
