Network Model Management

This 8-hour one-day course covers the operation of the ERCOT Network Model Management System (NMMS) and the associated processes. Attendees to the course will learn about the processes, procedures and activities that provide the necessary safeguards in modeling the ERCOT system.

This course includes:

• Instruction on the roles and responsibilities of ERCOT and the market participants (MPs) to maintain the ERCOT network models.
• Instruction on the management principles used to maintain a consistent framework for the network operations model, the congestion revenue right (CRR) auction model and the planning model.
• The impacts of potential changes to the ERCOT network models, illustrated by examples of typical transactions for transmission service providers (TSPs), qualified scheduling entities (QSEs) and ERCOT.
• The implementation timeline requirements for data submittals through the network operation model change request (NOMCR) and associated processes, including the prohibitions regarding the switching of new elements into the system without inclusion in the network model and authorization from ERCOT.
• The timelines for release of the model to the market, and the difference between posted incremental model releases and a full model release will also be discussed.
• Instruction on how an MP would use the NOMCR and the associated processes to update network models, manage outages, update protocol required information for any transmission element, coordinate switching of new devices onto the ERCOT grid with the modeling efforts and retiring of old devices from the ERCOT grid with their removal from the model.
• Introduction to the required data formats associated with NOMCRs and how to view the status of individual requests.

At the completion of this course, attendees should be able to describe the processes through which ERCOT will update and manage the network models.
