MISO Model Manager


The MISO Model Manager project is part of the larger Market System Enhancement (MSE) program to modernize MISO’s Energy & Ancillary Services Market systems.  Model Manager will modernize MISO’s modeling systems for meeting future performance, usability, reliability and security needs.  It includes the Siemens Smart Grid Engineering Manager (SGEM) application which will be configured to MISO’s specifications.  The MISO Model Manager will enable MISO members to submit and maintain accurate power system modeling data utilized in MISO’s real-time and market operations applications.

Frequently Asked Questions

The initial phases of the project will replace Extranet Modeling Webtool and Commercial model Attachment B model data submittal processes with MISO Model Manager and implement integrations with downstream model consumers. The MISO Model Manager is the Siemens Smart Grid Engineering Manager (SGEM) application which will be configured to MISO’s specifications.

Future phases of the project will integrate Operating horizon and Planning horizon processes to enable members to submit modeling data once to MISO for inclusion in all applicable models.

MISO Model Manager will NOT be used to gather MISO energy and ancillary services market data that is submitted via the Market User Interface (MUI).

MISO Model Manager is being implemented and is scheduled to start parallel operations in the 3rd quarter of 2021.  Member training will begin in August and parallel operations testing will start in September, 2021.  Cut over to the new modeling system is scheduled for Q1 of 2022.

MISO Model Manager is an extensible and scalable modeling system that can adapt rapidly to the modeling needs of a changing power grid. Current modeling processes are inefficient, and the cost to expand the model is high. The MISO Model Manager project will standardize and centralize the collection, organization and distribution of model data into MISO’s reliability, markets and planning functions.

The project will enable more frequent model updates and allow members to submit data only once for multiple MISO processes. It provides cost efficiencies through automation of model build processes and market efficiencies through improved validation of model data within a single source.

Members will be able to submit Network and Commercial model data to MISO with improved data visualization and validation. MISO Model Manager will provide members’ with timely feedback on data quality and completeness. Model change review status will be provided to members so you know your changes will be included in the models.

Methods and data formats to submit modeling data to MISO will be changing. Model data changes will be submitted via graphical user interface or Common Information Model (CIM) standards based XML formatted files. An application programming interface (API) will also be available to enable members to submit data from machine to machine.

The need to provide network and commercial model changes to MISO per modeling schedules.

SUSTAINED VALUE

  • Single system of record for operations, planning and market model data
  • Common Information Model (CIM) standardizes data definitions
  • Front-end data validation and visualization
  • Process automation with reduced building costs
  • Monthly model updates that reduce uncertainty
  • Standardizes data exchange with the EMS and market system that reduces model propagation costs

CUSTOMER SATISFACTION

  • Eliminates duplicate model data submissions
  • Graphical interface facilitates review and submission of model updates

PREPARE FOR THE FUTURE

  • Efficient scaling of models for new market products, Distributed Energy Resources (DER) and renewables
  • Integrated ratings process
  • Modeling data source to support members’ model updates

MISO provides stakeholders updates on the MMM at monthly Modeling User Group (MUG) meetings.  Training opportunities will also be communicated through this forum.  For notifications on meeting and materials, please sign up for the Modeling User Group distribution list under your MISO profile.

MISO will share the validation data with Market Participants for their review during Q3, 2021. 

MISO Model Manager performs data validations at several points in the data submittal and review process. Additional validations are performed by MISO after Model Change Requests are submitted to MISO Model Manager. Market Participants will be able to monitor their status throughout the review process. 

Yes, MISO Model Manager provides the ability for Market Participants to view their commercial model data and the status of changes to be included in future production models. 

Yes, MISO Model Manager enables electronic submission and review  for Commercial model changes with MISO Model Manager. 

Yes, MISO Model Manager enables radial line data submittal.
