The MISO Model Manager project is enabling MISO members to provide modeling data to MISO to maintain accurate power system models that are used by our real-time and market operations. MISO modeling systems required modernization to meet future performance, usability, reliability, and security needs. The initial phase of project for network and commercial models is complete. The next phase of the project includes planning horizon models.
MISO requires members to transition to the new modeling system. This change is part of the larger Market System Enhancement (MSE) program to modernize the MISO Energy & Ancillary Services Market system.
Phase 1 of the project has replaced Extranet Modeling Webtool and Commercial model Attachment B model data submittal processes with MISO Model. The MISO Model Manager is the Siemens Smart Grid Engineering Manager application which will be configured to MISO’s specifications.
Phase 2 of MISO Model Manager project provides internal data integrations to move modeling data efficiently to model data consumers within MISO. Phase 2 does not directly impact MISO members.
Phase 3 of the project will integrate Operating horizon and Planning horizon processes to enable centralized data submission by members to MISO for inclusion in applicable models. This phase will replace the Model On Demand system for MISO 2026 Series.
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). Financial Transmission Rights (FTR) models are a combination of operations and planning information. FTR models will not be made from Model Manager at this time. Planning horizon model are not included in the initial phase of the project. Model On Demand will still be used for Planning model data submittal until Phase 3 of project is completed.
Phase 1 is completed. Phase 3 implementation is scheduled for 2023 and 2024. Parallel Operations will happen during the MISO 2025 Series starting in Fall 2024. Please see Status Updates below for latest schedule information.
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 through a single system 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 are able to submit Network and Commercial model data to MISO with graphical user interface editing, improved data visualization and validation. MISO Model Manager provides members with timely feedback on data quality and completeness. Model change review status are available so members know your changes will be included in the models. Advanced modeling capabilities will be available to the MISO Series planning modeling process after Phase 3 is completed.
Methods and data formats to submit modeling data to MISO will be changing. Model data changes will be submitted via a 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 modeling data to MISO per existing modeling schedules.
PREPARE FOR THE FUTURE
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.
On-line training is available in MISO Learning Center. The instructor lead training sessions have been recorded and videos are posted on MUG extranet page. See latest Status Updates below for future training sessions.
