is your power utility smart enough to survive another decade
DESCRIPTION
Power utilities worldwide are looking for ways to extend the life of in-field assets while also improving service levels to power subscribers. Existing energy infrastructure deployed across our nation is largely composed of assets with extremely limited communication capabilities based on SCADA protocols, such as DNP3. By the end of 2024, over $7 trillion of infrastructure upgrades will be required. These challenges can be addressed with smarter distribution grids that control and monitor assets down to the level of neighborhoods and individual homes. These smart grids incorporate military-grade securable protocols and hardened architectures. They use hygiene services and bi-directional conversion to Data Distribution Service (DDS) software for all internal and intra-network signalling. And they source intelligence in nodes with continued secure communications to existing operational management systems. The result is distributed management, distributed intelligence and distributed security for high resolution analysis, implementation of evolving policy controls and reasonable price to performance ratio (IRR). This webinar, co-hosted by RTI and LocalGrid, will discuss the evolution and benefits of smart grids, as well as advancements such as: Localized control rather than centralized protocol hygiene (energy firewalls) Analytics and policy control rather than just security Over the air DDS-assisted updates to change duty cycle and capabilities, and reduce service costs Mesh-/fabric-based network topologies for self-healing, fault-tolerant networks (multi-master topologies) Verification of DR compliance using DDS On Demand: http://ecast.opensystemsmedia.com/443TRANSCRIPT

DDS: Enabling Smarter Distribution Grids

Centralized Monitoring and Control
• Constrains volume of real time data that can ‑be analyzed– Capacity of network links– Servers
• Poor latency• Single point of failure
• Doesn’t scale (cost, tech)– More sensors– Distributed generation
• Limits efficiency, responsiveness– Demand response– Fault isolation, correction– Predictive maintenance

Other Impediments to Modernization
• Protocols galore– SCADA, DNP3, IEC 61850, C37.118, proprietary– Expensive app development and integration
• Security

Data Distribution Service (DDS)
• Software “data bus”• Distributes data where its needed, when its needed• Completely decentralized

Simple Yet Powerful Paradigm
• Applications write (publish) and read (subscribe) data
• Like a database but for data in motion
• DDS automatically routes data between publishers and subscribers
• Data: raw, processed or commands• Decoupling: apps require no
awareness of source or destination• Normalized data model• Extensive Quality of Service

Decentralized Architecture
• Peer-to-peer communication– No centralized software, servers or message brokers
• Minimizes software infrastructure that has to be deployed and managed
• No single point of failure or choke point• Very low latency, high throughput, scalable

Broad Interoperability for Heterogeneous Systems
• Programming languages and environments– C, C++, C#/.NET, Java, Ada– REST/HTTP– LabVIEW, MATLAB, Simulink, UML
• Operating systems– Windows, Linux, Unix, Mac OS– Embedded, real time, partitioned– Mobile
• Processor families– x86, ARM, PowerPC– 32- and 64-bit
• Transport types– Shared memory– LAN (incl. multicast)– WAN– Wireless– Low bandwidth

Automatic Discovery EnablesAutonomous Systems• Plug and play, self forming, self healing• No system administration required• Automatic failover• Apps and devices are dynamically upgradeable– Never have to restart an entire system
• Apps can be notified when data sources/sinks join/leave (presence)

Minimizes and Optimizes Bandwidth
• Fine grained subscription control: by time and content• Only subscribed data is sent within or between subnets• Most metadata exchanged only at discovery time• Efficient binary encoding• Optional data compression• Connectionless: tolerant of intermittent networks
