Deploying CIM to Bridge the Modeling Gap Between Operations and Planning Mike usa.siemens.com/digitalgrid unrestricted © Siemens AG 2017

Innovative utilities are using CIM to deploy Network Model Management (NMM) solutions, that bring Planning, Operations and Energy Market models together, to eliminate duplicate efforts, increase reliability, and streamline compliance. Elevator speech on benefits of using CIM for NMM.

What is the CIM Standard? A tool that provides a common language An information model representing real-world utility objects Defines a standard data exchange format Provides application upgrade independence CIM allows companies to select the best choice of software tools for the job and not those from a single vendor just because they can communicate with each other.

CIM is a proven exchange method Tested by multiple users since 2000 Used by the ERCOT Nodal Model Management System since 2010 ENTSO-E planning model exchange using CIM since 2009 CIM is now a valued and proven standard in the industry, that is getting stronger and more defined every day. All changes are tested by multiple venders.

Why is a standards based model design innovative? It will allow you to take advantage of work accomplished before you You will get out of maintaining custom interfaces between software applications CIM will push data conversion effort to Vendors Software can be updated independently CIM is knocking down barriers between network modeling groups. One model for everyone.

Applying CIM to the Model Management Problem

Today’s model management problem Existing processes are not automated and are labor intensive and time consuming Lack of uniform, automated electronic coordination also provides opportunities for data errors Model inconsistencies between or within organizations cause inaccuracies in reliability evaluation Inconsistent models cause a significant direct negative bottom line impact NERC is enforcing modeling codes with audit trails for all model data There is a lot of wasted time and effort in maintaining duplicate models. Simple missed key can translate into bad decisions made from planning case results.

Work Flow: Operations and Planning Network Modeling Operations’ Needs Planning’s Needs Accurate cases representing actual past, present and future network conditions Efficient topology processor Real-Time Studies Robust state estimator Common language with Planning Efficiency when managing hundreds of designs Comprehensive contingency analysis Optimization analysis for real and reactive power injection Common language with Operations Capability to integrate future projects and models with present and past models Open architecture and common data exchange A Network Model Management solution will need to maintain the individual needs, as well as addressing the common ground. It is important to analyze all groups using network models to identify needs. Duplicate efforts in building models!

Common network model solution Use CIM as the standard based model exchange format Align planning, operations, outage, and asset management models Consolidate power system modeling functions across domains in a single source master repository The solution takes a standard, plus process, plus people to realize Network Model Management.

Network model management goals Uniform modeling between Planning, Operations and Energy Markets to… Synchronize workflow efficiencies Eliminate manual updating by multiple business units Increase reliability with data consistency Simplify compliance (ie. NERC MOD-33) Streamline model change collection Vet models for the state estimator Reduce EMS model build and deployment time With a unified system model utilities will see large efficiency gains, faster modeling updates, and more dependable results Vetting the network against a state estimator yields a planning model which produces accurate results.

Real world CIM compliant Network Model Management (NMM) solutions

What a CIM NMM software looks like Utilizes open CIM data formats, to break the dependencies on proprietary data formats Has a single data repository that is platform-independent (such as Oracle and SQL Server) Allows Modeling Engineers to work with a consistent set of data Enables compliance with North America (NERC) and European (ENTSO-E CGMES) data modeling and exchange standards Full auditing capabilities to track changes and recreate events Establishes a sustainable path to interoperability, and data governance Automates key tasks such as case assembly, data submission, and data validation Everything really relates back to CIM as the catalyst to make all of this possible… One model passed to multiple applications.

Siemens PTI PSS®ODMS NMM Solution: A CIM-based transmission network modeling and analysis tool CIM based PSS®ODMS is the centerpiece of the solution, with other needed software on the periphery One of the necessary (or unfortunate) evils today is the need for adapters, where software either does not fully comply with CIM or simply does not utilize it

Siemens PTI’s experience deploying PSS®ODMS NMM Solutions U.S. ISO - 2001 Australian TSO - 2004 U.S. ISO - 2007 European Utility - 2010 Fingrid – 2010 PSS®ODMS was built from the ground up to be a Network Model Manager PSS®ODMS has a long history in supporting Network Model Management AEP - 2017
