2021 Fall Reliability and Security Seminar Growing Variable Energy Resources and Grid Reliability
October 5-6 WebEx
Fall Reliability & Security Seminar
Agenda
SERC is committed to providing training and non-binding guidance to industry stakeholders regarding emerging and revised Reliability Standards. However, compliance depends on a number of factors including the precise language of the Standard, the specific facts and circumstances, and the quality of evidence. Purpose: To inform participants on the impacts of growing variable energy resources in the SERC Region, especially Inverter Based Resources (IBR) on Power Quality and Grid Reliability. Participants will explore best practices and lessons learned from performing various planning studies focused on IBR integration, as well as modeling and planning for growth in Battery Energy Storage Systems (BESS).

Proposed Modifications to the PJM Generator Deliverability Test to Better Handle the Evolving Resource Mix in PJM
This talk will begin with an overview of the changing resource mix in PJM and some of the current efforts underway at PJM to adapt to this new paradigm. The discussion will provide an introduction to the PJM Generator Deliverability Test purpose, study periods, and procedures, along with an overview of proposed modifications recommended by PJM that are being vetted through the PJM stakeholder process to better incorporate large penetrations of renewable resources. Jonathan will describe how traditional as well as Inverter Based Resources are modeled and dispatched as part of this steady-state reliability study. He will provide background on how regional deliverability requirements for wind and solar resources are derived and how they are applied on both a flowgate basis and on a zonal basis. Jonathan will also discuss how batteries are modeled and dispatched both as standalone resources and as part of hybrid resources. His discussion will provide some of the pros and cons of PJM’s proposed changes to its Generator Deliverability Test and highlight some of the challenges being faced as PJM seeks to implement the proposed changes.

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.
