NMM keeps your network topology and connectivity data consistent and up to date. Support planning, system analysis, and integration workflows with a reliable network model.
Network Model Management (NMM) provides a central topology repository, integrated with planning, simulation tools, EMS/DMS, and hierarchical structures. It offers a single repository concept for all consumers of the Network Model; moreover, it supports multiple users, model parts, boundary parts, workspaces, and model assemblies. As opposed to simpler solutions that track only the current version of the network model, the solution offers a complete audit trail over each granular change in the network model.
A Common Information Model (CIM)-based Network Model Management Solution provides and maintains valuable connectivity with users’ databases, data sources, applications, and Asset Management hierarchy. It effortlessly manages power system planning and development activities with the assurance of data quality and integrity and a fundamental single-source-of-truth basis.
CIM-Based Network Model Management Solution will ease integrations with your external sources of network and substation data, validate data before importing it, and maintain a full audit trail of changes. In addition, it will save time with Auto-Layout Diagrams Creation based on CIM Data.
Ready for CIM CGMES 3.0
We ensure compliance with CIM CGMES 3.0 by supporting CIM profiles within CIM 16 (IEC 61970 and IEC 61968 standards), including profiles for power flow, dynamics, short-circuit analysis, and other relevant applications.
We actively participates in ENTSO-E CGMES 3.0 interoperability workshops to ensure seamless exchange of grid models and data among different utilities and systems and to demonstrate and to validate its compliance with CGMES 3.0.
During these workshops, we collaborate with other vendors, identifies potential interoperability issues, and stays updated on latest developments and best practices related to CGMES 3.0.
NMM uses CIM 16 as its base, defined by the IEC 61970 and IEC 61968-4 standards and provides a standardized framework for exchanging grid models and operational information among different enterprise systems in the electrical power industry.
Native CIM-based Data Repository
Repository stores CIM data in native format within its relations, classes, and attributes, which has a huge advantage in terms of data management flexibility and performance compared with triple-state databases or even flat files. It stores CIM data in its native format meaning that the NMM can store MRIDs and exchange CIM data without conversions or MRID recalculations.
User Interface and Visualization
NMM model part explorer module provides user-friendly navigation either through the list of model parts, model part branches, and versions, or through graphical branch representation. IPS®NMM diagram view module provides a hierarchical rendering of CIM data using the equipment container’s hierarchy.
Version Control System
The version control concept is far more than a simple data audit trail. It enables branching, merge, and rollback operations, and the versions are assigned to CIM change sets.
Advanced Validation Rule Engine and Scripting
Validation module provides an infrastructure for a user to specify as many validation rules in runtime as necessary and store these in the IPS®NMM database. Once stored, the validation rules can be executed on-demand in any active model part version (model loaded to the application). Users can configure their own rules and scripts using Python or C# scripting. The validation rules are processed by the internal rule engine. IPS®NMM comes with out-of-the-box Level 3, Level 4, and Level 5 ENTSO-E Validation Rules, which can be used to verify and validate data after it is created, approved, imported from enterprise data sources, or before being sent to network model consumers.
IPS® Identity Provider and Authorization Server
Best practices in Cyber Security Authentication and Authorization, transparent IPS® Identity and Access Management.
WebAPI
The NMM fully supports secure CIM-based integration via RESTful Web API or direct file exchange through import/export options. RESTful Web API allows the execution of internally stored Python scripts and validation rules; it also enables browsing and CIM-level CRUD operations on CIM objects. Storing data in its native CIM format eliminates conversions and ensures vendor-agnostic, seamless CIM CGMES interoperability, compatible with current and upcoming CIM CGMES 3.0 profile versions.
File Exchange
The NMM supports the import and conversion of PSS®E .raw, .sec, and .dyn files to CIM and the reverse conversion back to PSS®E. Object registry data mapping between external systems ensures smooth integration.
Baseline for Outage Management System
Once a validated NMM model is in place, it can be shared or integrated across various systems, including the IPS CIM-based Outage Management System (OMS). OMS determines outage groups by engaging in a topological/connectivity search. It identifies which substations and topological elements are connected through specific overhead lines and conducting equipment. Afterward, it determines the associated assets and planned maintenance activities for each outage group during an outage event.
Facility Ratings – FERC Order 881
Ratings and several rating types can be integrated with external systems or defined within the IPS standard Advanced Facility Ratings Management tool.
