Cimphony Concert

Cimphony Concert is a scaleable, next generation Open Data Engine (ODE) for managing power system data. Cimphony Concert allows users to create a Digital Twin of their system, acting as a Network Model Management (NMM) system with full historical tracking of changes using a blockchain architecture. The system supports the automatic integration of the as-built electrical network asset data with high-volume real-time data from smart metersphasor measurement units, and SCADA measurement points.

Cimphony Concert is the core database for the industry-leading Distributed Energy Resource Management Systems (DERMS) solution, delivering scalable, high-performance, redundant data storage built on the IEC 61968/61970/62335 Common Information Model (CIM) standards. The ISO/IEC standard OData API provides a rich, standardised API with support for complex querying and integration into standard office tools such as Sharepoint and Microsoft Excel.

Digital Twin

Cimphony Concert is built to support large, complex data sets, supporting the management of full distribution systems and high volume real-time data sources as a fully integrated digital twin.  Deployments of Cimphony can store hundreds of millions of data elements and billions of smart meter and PMU readings.

Security

Cimphony Concert is designed to support on-premises and cloud deployments on AWS and Azure, with role-based access controls, support for federated identity management, redundancy, encrypted communications, and encryption at-rest.

Data Visualisation

Cimphony Concert has its own web based user interfaces for data browsing and editing, and integrates with other Open Grid Systems’ products including Cimphony Orchestra and Grid Insight to support data editing and advanced data visualisation using 3D geographical and schematic interfaces.

Micro Service API

Cimphony Concert implements a micro-service interface built on the ISO/IEC OData v4.0 RESTful Application Programming Interface (API) standard. Through this interfaces third party systems can access data at multiple levels of granularity, with full meta-data access.

This approach to external interfaces allows for applications to build their own data interface specifications with a combination of search parameters, filters and expansions to define the query and resulting payload, rather than relying on static, pre-built interfaces with fixed structures.

The interface provides a machine-readable meta-data definitions using the standard OData Entity Data Model. This allows external systems to access a fully annotated meta-model definition directly from the API including data types, relationships and properties.

The event-driven notification interface allows systems to register for changes at the data-set, type, record or property level. This enables real-time integration between multiple systems using a micro-service architecture built on open, secure RESTful APIs.

OData v4.0 API

Cimphony Concert uses the IEC/ISO approved OData standard to define its RESTful API. This OASIS standard is supported by multiple external systems including standard productivity software including Power BI and Microsoft Excel.  The API can be used with OData client libraries or as a simple RESTful endpoint accessed using standard HTTPS connections.

Event Driven Notifications

Cimphony Concert manages and tracks all changes to data within the underlying databases.  External systems can register to be notified on changes to data in real-time. This is used to manage the interactions between Front-End ProcessorsAnalysis Engines,Market Participants, and Market Balancing Engines in next-generation DERMS platforms.

Complex Queries

The OData interface supports complex queries, with filtering, sorting and expansion of associated data elements. This rich query language allows external systems to access as-built, realtime and historical data via the RESTful API.

Grid Reporter

Grid Reporter is a smart-phone application, allowing customers, internal staff, emergency services, contractors and other utility personnel to report outages, damaged equipment and fallen lines on Android and iOS devices.

Grid Reporter provides improved customer engagement with sub-30 second submission of outage or damage reports with an automated, real-time identification of the corresponding electrical network component based on the submitted geographical data.

An attached photo allows the operators to quickly determine if the faulty equipment is one of their own assets.

Improved Resoration Time

Customer-submitted photos allows for faster assessment of damage by operators to reduce restoration time and customer minutes lost.

Data Quality

Accurate location data from smartphone GPS & magnetometer combined with customer-verified matching, allows for accurate fault location identification.

Instant Report Submission

Reduction in time to submit an outage report compared to traditional call centre based reporting. During extreme weather events the system allows customers to submit reports instantly, with automated messages informing them of any ongoing problems on the network.

SSEN Power Track

Open Grid Systems also create white labelled versions of Grid Reporter so the Utilities’ own branding and styling can be incorporated. Scottish & Southern Electricity Network‘s (SSEN) Power Track App is an example of this and has been successfully used by SSEN since 2018.

SSEN serves 3.7m customers on their networks across central southern England and the north of Scotland.

Power Track is available on both iOS and Android, offering SSEN’s customers a way to view, report and be notified of planned, live and resolved faults on their network.

SSEN’s customer relations personnel use Grid Insight to view customer submitted reports, respond to those customers, and dispatch crew to the right areas to rectify the faults.

Grid Insight

Grid Insight is Open Grid Systems’ data-driven  geographical and schematic interfaces.  Grid Insight provides rich web-based user interfaces for visualising and interacting with large, complex data sets using cutting-edge 3D interfaces.

The animated display at the top of this page is an example of the DERMS visualisation plug-in for Grid Insight running on IEC CIM data from Cimphony Concert, combined with power-flow results from the DERMS Analysis module.

Grid Insight is used by utilities for network situational awareness, interacting with customer submitted outage reports, running historical data analysis, and for real-time notification of network incidents including lightning strikes and customer reports of damage to the network.

Lightning Tracker

Real-time and historical lightning strike visualisation. The system performs real-time matching of lightning strikes with a complete system analytical model in IEC CIM covering transmission and distribution.

Any lightning strike is matched with network assets in real-time, with control engineers notified of potential lightning strikes on the network < 10 seconds after the strike has occured.

Historical analysis mode allows time and spatial based searching of 10+ years of lightning strikes.

Grid Reporter

Grid Insight is the platform for the administrative interface for Grid Reporter. This provides customer service representatives with an overview of the reports submitted by customers and the ability to message customers directly regarding their outage/damage report.
