The Role of GIS in the Smart Grid
As two-way communications enhance dialogue between power consumers and suppliers, network operators are beginning to require location as a standard for effective system management.
By Christine Easterfield
Many factors are changing the way our energy networks operate: regulatory agencies, the rise of renewable energy sources, and smart technologies that drive intelligent devices in the home or along the network. As the electrical power grid grows ever smarter, these developments are causing organizations to take a closer look at the technologies that support the management and operation of the network.
Up to now, energy networks have been a one-way channel from generation to consumption, but emerging technologies that enable two-way communications are creating the possibility of a dialogue between the consumer and the supplier. This results in a consumer who knows in real time how much power they are using (and at what cost), and a utility that has better management, pricing, and forecasting tools for its network.
It also blurs the distinction between consumer and provider, enabling the customer to become an occasional supplier as local generation facilities and the use of electric vehicle batteries for load-balancing storage become a reality. Manufacturing businesses may even find themselves making minute-by-minute decisions about switching on their generators, either to send power to their factories, or to sell it to the grid.
Who, What, and Where
This greater involvement with the energy consumer has implications for the records that infrastructure companies maintain. What we used to call "mapping the last mile" — referring to the leg of the network that reaches the customer — is now crucial to understanding how each consumer is connected. Network managers need to know where a far greater number of occasional, distributed generation points (such as industrial sites or rooftop solar panels) connect with the grid, and what impact they have on the overall power flow.
Location has always been a crucial consideration, whether network operators are calculating losses, balancing loads, or planning new extensions. These latest changes create demand for technology that has location as a standard component, supporting new devices, software, and services throughout the system — from the generation plant to the consumer's meter.

With its acquisition of Pointools, the infrastructure software provider prepares to leverage a new fundamental data type across the ProjectWise and AssetWise platforms.
By Cadalyst Staff
During its Be Inspired: Thought Leadership in Infrastructure event held in Amsterdam last week, Bentley Systems announced the acquisition of Pointools, a developer of hardware-neutral point cloud software. The purchase comes two years after the two companies signed a technology agreement allowing Bentley to embed Pointools' Vortex API engine in MicroStation. With the new acquisition, Bentley plans to assimilate point cloud processing and data management throughout its ProjectWise and AssetWise platforms.
As scanning hardware prices fall, point cloud capture is becoming ever more affordable, but the data is often limited to temporary, task-specific purposes because the outsize files defy storage and querying. "The scale of the files has meant they're not as useful as they could be throughout the project," CEO Greg Bentley explained during his Be Inspired keynote address.
With those challenges out of the way, point clouds, as a fundamental data type, can serve as "as-operated" 3D models for infrastructure assets. "Point clouds no longer by virtue of their size need be throwaways," Mr. Bentley continued. "We have the opportunity now to include point clouds in all of our workflows." Read more »
