MISO Distributed Energy Resources Journey

The seminar will focus on MISO’s DER integration journey. The purpose of the seminar is to cover the various drivers and responses to MISO’s evolving DER implementation. The initial representation began in 2018 with a simple request to identify where these resources exist, and identify MISO’s planned management of the data. In the past few years, Behind the Meter Generation & DER in particular have become a stable data source for reliability modeling within MISO. Creation of a new workbook for meta data behind DER has simplified the fuel variability of these injection sites to simple formulas, which exist outside of the PSSE case. This workbook has been able to alleviate numerous concerns of members that data will be used in unexpected ways. This transparency has also been expanded to include Transmission-interconnected intermittent resources. The exponential growth in representation of DER in MISO has benefitted from this augmentation.
