A revised IEEE 1547 is going through the IEEE balloting process and is expected to be finalized in February/March of 2018. The revised standard streamlines the advanced grid support functions that Distributed Energy Resources (DERs) can provide to help mitigate power quality and bulk system stability issues. These functions include but not limited to volt/VAR, frequency regulation, ride through, etc. However, the implementation of DERs with these advanced functions will not be straightforward and will most likely require distribution engineering planning studies to determine how they should function with legacy systems, including existing inverters and other power electronics technology, and to ascertain what additional requirements are needed for sensing, control and communication infrastructure. In this session, we will examine issues and recommend strategies to address advanced DER implementation challenges.
