The document discusses how integrating GIS with other systems using a common data model, such as the PowerGrid model, can optimize electric utility grid operations by providing a single source of consolidated network data. This allows data to be shared across applications such as DMS, asset management, and planning systems. The example of the Finnish utility Fingrid's project demonstrates integrating GIS with IBM Maximo for asset management and extracting network data in CIM format for transmission planning software.

Informi GIS Handout Following Presentation at Esri UC 2014 Informi GIS A/S Author: Jens Dalsgaard July 4th 2014 www.informi.dk http://www.linkedin.com/in/jensdalsgaard Visualizing Knowledge Optimizing Electric Utility Grid Operations through GIS and Powergrid - Integrating Asset Management & Extracting to CIM Summary: Previously siloed systems are broken down and data is increasingly shared across lines of business. For an electric utility operator the most fundamental data is the network model. With the right network model, grid documentation can be shared between applications, thus ensuring consolidated data usage. GIS is the logical center for electric utilities. Implementing the PowerGrid data model en- sures that grid documentation can be shared across platforms like DMS and asset man- agement. Besides this, in GIS itself offers great support for in-field crew and central dis- patching teams.

Optimizing Electric Utility Grid Operations Using GIS Informi GIS July 4 th 2014 Page 2 / 12 Jaegerborg Allé 4 DK - 2920 Charlottenlund Phone: +45 3996 5900 Introduction Typically, Electric utility companies have acquired or developed a large number of extremely specialized software solutions to support specific challenges met in the business over the years. But often such systems are custom developed and are referred to as point-solutions – they may each be useful in a specific context, but there’s a lack of consistency and coherence in between the many systems. Each part-solution requires specific data to operate so users must obtain separate skills for each application. Thus, upholding opera- tions and services for the many diverse applications can take its toll on the IT-department. As the electric utility companies continue into the digital age, former previously siloed systems are broken down and data is increasingly shared across lines of business. For a grid operator the most fundamental data is the network model. The advanced PowerGrid data model from Informi GIS allows focus on a single network model shared between applications which support business needs in a much broader perspective. Various Complex Tasks in Electric Utility Operations Today an electric utility must be able to support a large number of complex tasks – a few examples are: Optimizing grid operation during highly fluctuating production and consumption Optimizing asset life cycle cost and operability Extracting asset data for benchmarking, valuations etc. Supporting the various planning phases Protecting buried assets from excavation damage Calculating overhead line sag Calculating induced voltage on nearby underground pipelines Pinpointing fault location, based on distance relay output Planning outages and switching operations Supporting field crew operation Keeping track of field crew position Ensuring management, overview of grid operation, planned service … … It is fairly obvious that IT-solutions are needed – but which and how? This paper aims at briefly describing an approach and a solution that ensures consolidated grid documenta- tion using the ArcGIS solution from Esri. A solution built on 20+ years of experience in delivering solutions to electric distribution and transmission utilities; a solution that proves useful in all of the above mentioned tasks and many more.

In order to maintain its position among the most reliable and lean TSO’s, Fingrid needed a robust, flexible and fully integrated grid, asset and work management system – data should be entered once and distributed as needed. The winning solution had ArcGIS as a cornerstone component. The ELVIS project was a rare opportunity to build a fully coherent solution, combining best in class products, industry standards and stringent architec- tural principles. As intended, it serves as a “point-of-reference” system for any modern network utility. The ELVIS solution delivers a consolidated grid design, asset and work management solution. Centered on the electrical grid model the solution supports key planning areas such as project management as well as grid and asset modelling though out the asset lifecycle. In this project the Powergrid data model from Informi GIS is essential. Besides providing a data foundation for DMS and asset management systems, the GIS solution in itself sup- ports a large number of business processes related to data maintenance, grid planning, field crew support etc. The presentation by Informi GIS, IBM and Fingrid at Esri UC 2014 gave a glimpse into this solution - we’ll readily elaborate on this upon request. 1 http://www.fingrid.fi/en/company/elvis/Pages/default.aspx

Optimizing Electric Utility Grid Operations Using GIS Informi GIS July 4 th 2014 Page 4 / 12 Jaegerborg Allé 4 DK - 2920 Charlottenlund Phone: +45 3996 5900 Smart Grid – Definition and Ways of Optimizing Grid Operation You have probably all seen several definitions on Smart Grid – but let us here add another definition here: “Automating an optimized grid operation despite significantly fluctuating production and consumption – to largest possible extent even during faults.” Power production depends more and more on how the wind blows and how the sun shines. Consumers are expected to act more on market fluctuation – when energy is cheap, more will be used. Metering and forecasting consumption is part of the picture, and many vendors offer solutions for this: However, metering alone leaves out a crucial part of the equation: The grid itself. In order to optimize grid operation (minimizing losses, avoiding overloading/damaging equipment etc.) we must know how the grid is connected what types of cables/overhead lines transport the energy where the customers (loads) are connected in the grid … In the following pages we’ll take a look at how GIS lets you document such data – in doing so we’ll be look- ing at an example from one of our electric utility distribution customers. Figure 1: Metering voltages and power flow in substations and at customers offers useful input when optimizing grid operation

Also, the substation layout is registered revealing transformers, bus bars, bays, breakers etc. – obviously including how everything’s connected (internally as well as to external cables/overhead lines) and with property data. The cables/overhead lines shown above colored by feeder also are shown connected to the bays in the substation. 2 Besides allowing documenting projects using versioning. Figure 2: Part of a typical low voltage cable and overhead line grid. The coloring here reveals what is fed from which bay in the substation in question. The yellow rings reveal relevant tie points that are useful in switching operations during faults.

Data on consumption, customer type etc. is automatically updated based on regular extracts from a relevant third party system. Here loads are symbolized with circles revealing annual consumption. Figure 3: The same part of the grid this time symbolized by type of cable / overhead lines. Although connectivity is a crucial part of the equation, there are many other important aspects. For in- stance, the GIS data model holds information on types of cables, overhead lines etc. Crucial data on trans- formers, circuit breakers, fuses etc. is also documented… Combining this grid documentation with customer and load information extracted regularly from a billing / AMR system GIS offers the consolidated picture of the grid allowing advanced analyses used in optimizing grid operations.

This CIM XML is subsequently imported into a market leading software package used for transmission plan- ning and analysis (fault analysis, contingency analysis...). The PowerGrid data model and Esri ArcGIS thus provide the foundation for efficiently establishing and maintaining the complete grid documentation needed in grid operation optimization.

It’s worth noting that a lot of asset management related tasks can be handled by using GIS alone. Besides allowing reports needed in benchmarking, valuation etc. GIS offers the ability to visualize e.g. re- cently completed as well as upcoming service tasks, perform automated route planning and assign tasks and corresponding routes to individual field crews. Central dispatching units may visualize in a map where specific service cars are and use this in e.g. assigning ad-hoc tasks. Management and planning teams may easily follow progress using dashboards that reveal KPIs using ArcGIS standard functionality. For the field crew, GIS offers flexible tools allowing easy access to relevant data. Besides accessing data needed in the field, the field crew may in the field document tasks performed etc. – even take photos and assign these to document certain issues. Standard mobile devices may be used –laptops, tablets or smart phones – no expensive and hard to service special equipment. Some companies prefer devices that run Windows, others prefer Android or IOS (Ap- ple OS) – all of these operating systems are supported. When moving into areas with limited network cover- age the user may go off-line and still access data – once back in areas with network coverage, changes can be synchronized. In this way, GIS is used also in optimizing in-field ser- vice planning and execution, which further optimizes electric utility operations.

The main functionality of the Maximo asset register is to hold information about the assets, their specifica- tions, the costs for maintenance, and their condition. The Location and operating function of the assets is maintained, enabling tracking of individual assets between locations and functions. This also includes ad- vanced grid value calculations as well as loadability and hazardous voltages calculations. For work/maintenance management Maximo is used as a way of automating and orchestrating business processes with relation to managing work orders and the associated resources, service providers, schedules and cost, while capturing the resulting changes to condition or cost figures at the location or asset level. IBM has implemented a two-way integration between GIS and Maximo allowing needed data to flow from GIS to the asset management system – and vice versa. When new grid is being documented in GIS, integra- tion ensures the correct generation of corresponding entities in Maximo. nd when asset data is en- tered/altered in Maximo, integration makes it available in GIS. Such consolidated and integrated data management further increases the value of data and allows the cus- tomer to optimize the system usage and value.

Initial migration from previous source systems allows good starting point but most likely won’t get you all the way. Besides this, users may make mistakes when editing data. ArcGIS holds efficient tools for analyzing and verifying that the data quality requirements are met. Where requirements are not met, the user is guided to data needing further processing. ArcGIS offers useful functionality to experts throughout the organization that work with the grid – be it the central planning team, the field crews doing maintenance, the dispatching teams, the outage management teams or management. And it’s a well-known fact that nothing works better in establishing and maintaining a high data quality than offering useful functionality to the experts throughout the organization that actual- ly work with the grid. The ability to easily access GIS data through fully fledged desktop applications or through standard web browsers and using standard mobile eases deployment, ensures return of investment and helps ensure da- ta quality that makes the difference between actually being able to optimize grid operations or simply dreaming of it.
