Digital Substation Engineering Is Future-Proofing the Grid
Time has not been a friend to power grids across the world. What has largely been a mechanical and physical environment since the dawn of grid energy has not adapted to change very well. So much of the grid is terribly outdated for this very reason. But as utilities are systematically implementing upgrades, they are also bringing substations into the digital realm. They are future-proofing their infrastructure at the same time.
Future-proofing is not about preventing any and all changes in the future. It is about building systems that easily adapt regardless of how things evolve. It is something the grid has lacked since its inception. But thanks to digital substation engineering and other future-proofing policies, we are changing that.
The Digital Transformation Comes to Energy
Business operations have been embracing the digital revolution for years. It is a revolution that should not be confused with digitization.
Digitization is little more than transitioning from paper documents and other legacy records to their digital counterparts. Digitalization goes far beyond documents. It is the process of replacing all sorts of legacy tools with better alternatives built on top of digital technologies.
In the substation engineering world, the most prominent example is the virtual substation. A virtual substation is a software substation hosted in the cloud. Software and digital components replace the physical components in a physical substation.
The fact that the digital transformation has finally come to the energy sector is huge. Its implications are still not fully understood. But we expect most of it to be very, very good.
Why Digitalize the Substation
All of this raises the question of why we should digitalize the substation. Consider the following five benefits of doing so:
Data-driven Decisions – Digitalization opens the door to real-time monitoring and predictive analytics. Both produce invaluable data that drives decisions regarding maintenance, upgrades, etc.
Integrated Resources – Distributed energy resources and renewable generation are fully integrated with more traditional forms of generation distribution through digital technologies.
Efficiency – Digitalization brings automation, remote operation, and reduced hardware needs to substation engineering. The substation is more efficient as a result. It is also less expensive to maintain and operate.
Reliability – Digitalization opens the door to better production schemes, dynamic controls, and built-in scalability. The result is a substation that is more reliable and flexible.
Safety – Because digitalization encourages remote maintenance and upgrades, there is less of a need for technicians to physically visit substation sites. They are safer in their day-to-day work.
Digitalization keeps the best of the physical substation environment and combines it with digital alternatives for the rest. The combination creates a powerful piece of infrastructure that is future-proofed against whatever comes down the pike years from now.
Its Time Has Come
In a way, it's almost a good thing that the grid has not kept pace with the rest of the world. Why? Because it is now easier to make the case for digitalization. The time has come for digitalization to take its place throughout the energy sector. There's no better place to start than substation engineering.
From virtualization to predictive analytics and remote monitoring to maintenance, digitalization pulls the doors wide open to new technologies that are literally transforming how we engineer modern substations. It's an exciting time to be part of this industry.
Here at Commonwealth, we are firm believers in upgrading infrastructure to meet modern technological opportunities. Where systems can be improved through digital technologies, they ought to be. It makes little sense to ignore digitalization when it has proven so helpful in so many other industries. It can be equally helpful to energy distribution.
