The power grid isn’t what it used to be. Grid operators need to address the growing challenges of a new “active grid,” which requires integrating microgrids, renewables, demand response, and customers that not only consume energy but produce it, too (Figure 1).
For systems integrators (SIs), this represents an opportunity to be on the leading edge of a massive technological investment. Their power provider customers now need generation and energy management capabilities all the way down to the low-voltage distribution network.
But the new active grid needs a level of visibility and control that existing systems and methods can’t provide. SCADA systems, for example, don’t do a very good job of allowing operators to peer into what’s happening at the medium and lower voltage levels of their grids. Instead, utilities need scalable control systems capable of integrating Internet of Things, edge intelligence, and Big Data technologies.
Existing control systems can give operators visibility into the higher voltage layer but are largely blind to the lower layers, where more and more energy assets are being added. “That’s causing a lot of disturbances,” said Juan Prieto, senior manager in charge of energy modeling and control systems at Indra.
“It’s causing transformers to burn up and taking voltages out of control,” he continued, “and utilities do not have the tools to monitor what’s going on and do something about it.”
Utilities and the SIs who serve them need a unified platform that can integrate and manage all grid assets at the edge, manage the massive volume of information generated by the Internet of Things, and enable future scalability. That’s what Indra and Intel offer with Indra’s Active Grid Management Suite (AGM)—see Figure 2.
The Indra platform combines an open architecture with state-of-the-art distributed analytics to monitor and manage a wide range of energy assets across the grid. The solution helps customers:
- Reduce costs by optimizing asset monitoring and management across the grid
- Improve grid reliability through real-time diagnosis and optimal response
- Provide real-time information exchange among systems regardless of manufacturer
- Furnish a comprehensive view of all monitoring and control resources while avoiding vendor-locking and bottlenecks
- Enable new use cases through insights gained from grid interoperability, scalability, and analytics-driven insights
And for SIs who specialize in utilities but aren’t as familiar with IoT technologies, partnering with a solutions aggregator—who can work with them to sell, customize and quickly deploy a repeatable solution—can help.
Lowering Costs and Carbon Emissions
Smart management can benefit your utility customer in a number of ways.
It can reduce costs by allowing assets to run closer to their design limits, which optimizes their productivity. That enables operators to remove excess capacity from their grids. The life of the asset can also be extended by better maintenance management based on the system’s better handling of information.
Smart grid management can also decrease carbon emissions. It smooths the integration of alternative energy sources—wind, solar, and such—to the grid. It also allows energy to be produced closer to where it’s consumed, which not only saves on transmission and distribution costs but on fossil fuels required to support higher transmission and distribution levels.
Managing on the Edges
At the heart of inGRID AGM are intelligent edge nodes based on Intel Atom® processors. The gateways gather information from energy assets on the grid in real time, and perform analytics on that data. “Because you have intelligence capability at the edge, you don’t need to send raw data in massive volumes to the operator for a decision,” Prieto explained. “You can filter that information, analyze it, and send only what is relevant for the operator to take into consideration.”
Information on the system can be shared among the edge nodes, the cloud, and legacy operational technology systems through Indra’s bus architecture. Such sharing facilitates monitoring, analytics, and asset optimization. From the cloud, the data can be represented in dashboards and reports, which in turn can be used to simulate asset changes or have big data analysis applied to it with Indra’s analytics software.
The inGRID AGM suite offers a number of benefits. For example, Indra’s iSpeed bus can increase compatibility across a wide variety of vendors and protocols. In addition, Indra’s monitoring portal can perform centralized, real-time grid asset monitoring of all voltage levels, and generate early warnings.
The suite also has a built-in what-if analysis tool for simulating changes before they’re performed, and powerful analytics for discovering trends and predicting outcomes from both historical and real-time information. What’s more, the suite can handle multiple use cases, such as medium- and lower-voltage monitoring, asset condition monitoring, distributed energy resources, and DR integration. This is good news for SIs, who can expand their offerings to include new use cases and post-deployment monitoring.
Indra’s edge nodes can also issue corrective instructions to assets, like batteries, to enable them to “self-heal,” and configure assets automatically to compensate for faulty assets or redirect power to where it’s needed most.
Partnering with Intel
Indra has partnered with Intel since 2015 because of the chipmaker’s proven track record in processing volumes of data generated from an IoT deployment. “Everything is about processing the information on the grid,” Prieto said. “If you can’t process it, you will not be able to react fast enough. You will not be able to add value and improve how you manage these systems.”
Intel® hardware and software allow Indra to offer an end-to-end solution. Gateways based on Intel® technology provide the edge processing needed for the smart energy grid, driving reliability through edge device management and robust security features. Intel also provides powerful cloud computing through Amazon Web Services servers built on Intel® Xeon® processors.
Intel components are also designed to operate in a variety of conditions. “Some have to work in the field, processing information generated in substations and distribution transformers under extreme external conditions,” Prieto explained.
“And they need to be secure because as you open an infrastructure to monitor more elements, the more open it gets, the more risky it gets,” he continued. “Intel chips incorporate hardware encryption technology to ensure the secure exchange of information on the system.”
The bottom line? SIs have a new opportunity to help their power providers accelerate their journey to the smart grid—and to help their customers successfully manage their grids with post-deployment services.
Opening New Opportunities
With better control of the grid, new business models may begin to emerge. Organizations may want to have smart grids of their own. Operators could provide services related to those “micro grids,” especially with the help of knowledgeable SIs. At some point, even individual consumers could become energy brokers. If they have excess power from their solar panels or are going on vacation, with the help of the smart grid, they could sell power to their neighbors.
“This infrastructure will allow new markets to happen,” Prieto said, for end-customers and SIs alike. “This isn’t science fiction. We’re seeing it happening now.”
