The deregulation of the 1990s to today’s constantly changing and evolving power generation product portfolio the industry has had to adapt and everyone knows there will be more changes. In recent years, the technology of the power generation industry has developed rapidly. Processors are getting faster and cheaper. The network is constantly evolving and availability is increasing.
The Industrial Internet of Things (IIoT). In March 2014, a group of visionary companies came together to form the Industrial Internet Consortium (IIC). The charter aims to gather the organizations and technologies needed to accelerate the development of the Industrial Internet by identifying, combining, and promoting best practices. In short, the participants recognized the evolving landscape of various industries and the need for fair norms and standards for the development of industrial / autonomous systems. Now, IIC has become a leading resource for all industries developing through the Industrial Internet type.
The autonomous systems are everywhere, from shared roads to drone inspection infrastructure. There is a big difference between these fast-autonomous systems and network control systems and can’t work in seconds or minutes. They can make decisions and take action in seconds without having to transfer large data files to the server and wait for instructions. They interact to optimize and communicate. It happened quickly. When things happen quickly, demand changes. The same is true of the energy sector. We can see that the electricity produced by fossil fuels is getting less and less, and the advantages in terms of economics and renewable energy at retirement are becoming more and more obvious. The problem is that large rotating coal-fired power plants cannot easily be replaced by thousands of small residential distributed power sources. By focusing on the factory, we have excellent predictability, outstanding performance, and a deep understanding of dynamics. With the influx of distributed energy and these things have changed a lot.
Our world gets closer and the advent of countless new connected devices, traditional hub and spoke systems are beginning to collapse. All server-based control system and optimization systems, there is a delay. Moving information from field devices across the network to server-hosted applications takes time. Server-hosted applications require a lot of work to read packets, package and transfer the packets over the network, decompress them, and write them to a database. In Traditional spoke architecture it takes time to suitable for large-scale centralized and slow-changing systems, but it cannot reduce speed and performance. In high-performance systems, the server exists but does not depend on Instead data and equipment are the focus. IIoT systems are all about performance; mission-critical, lifesaving, scalable, secure, more detailed than using a smartphone to turn lights on or off. However, in order for these systems (or even systems of systems) to exist, instant and accurate data must be provided in the required form, the required location, and the required security. For many years, IIoT has been addressing these requirements with data-centric and data bus concepts.
For years, when migrating to a distributed system is ownership and access. The utility systems have focused on what the utilities have. The equipment, network and land are strictly controlled by the utility company. Today, this ownership model has completely disappeared. Influx of distributed energy comes in many shapes, sizes and ownership. However, just because the utility does not own it does not mean that it does not contain important information. IIoT systems allow utility companies (almost all participants) to obtain secure real-time information about relevant data through any type of network infrastructure.
In power industry the data-centricity is a relatively new concept. The world has been able (and working well) to scan devices and communicate instructions in seconds or even minutes. With this setting, there is no need to be data-centric. When requirements change considering frequency or voltage support, different systems, fast control, etc. the data must be centered. Data round trip from device to server to server is very time consuming.
Data-centric can authorize the data on the device and then provide it to any connected device or system through the data bus. Through a data framework called a publish / subscribe device, the device can publish data to a public virtual network connection and any number of subscribers can receive the data. In the publish as long as you use modern IIoT data connectivity software such as data distribution services, latency is very low. In order to power on the connected devices, the data bus and the data of the connected devices need to be enabled. Back to the data-centric discussion, the data bus becomes the main component. Just because the device has modern IIoT capabilities, it doesn’t mean much if it can’t connect to and communicate with devices with similar capabilities.
The core tasks of the Industrial Internet include: enhancing the safety of global military capabilities, system proficiency precise over spread edge to back-end, analysis with plug-and-play capabilities, and application optimization and management.
Grids are usually focused on resilience utilities, military, college campuses, hospitals, municipalities and everyone are looking to increase resilience. Resiliency can be achieved by providing a decentralized architecture in IIOT design that can be reconfigured immediately. Then, for devices, software, subsystems, and back-end computing environments, subsystem discovery and fault-tolerant failover become necessary. Resiliency improves when the data needed to optimize the system does not need to be transferred between servers which may or may not be available. Without a single point of failure, fault tolerance will be greatly improved. As we move confidently into the future of influx of distributed energy, utilities and power generation companies must use the power of IIoT to quickly integrate proven applications into larger system systems.
Not only does influx of distributed energy exist, it will also have a direct and tangible impact on the future of the grid. Although the way forward is still blurred, the learning and standards deployed through IIoT systems will greatly promote the development of the power grid. Indeed, we are fortunate to have the support of giants in the electrical industry.
