Market Trends

Transition from Conventional Substations to Fully Digital and Intelligent Grids

 Conventional substations were characterized by fragmented control systems, a lack of data visibility, and a wait-and-watch approach to maintenance. All this has led to system downtime and a greater risk of failures. Today, the industry is adopting digital substations that are replete with intelligent devices and standardized communication interfaces. The effect has been a system that can track events in real time, detect potential failures before their occurrence, and implement control operations from a central point. The results include seamless information flow between substations, faster identification and isolation of faults, and optimal usage of assets. Digital substations have overall improved the stability of the grid system and reduced losses. They have ensured more optimal usage of the increasing electricity demand."

Rapid Integration of Renewable Energy and Distributed Power Sources

The accelerating integration of renewable energy sources has emerged as a defining trend in the substation automation market.. In traditional design concepts, there was a unidirectional flow of power from generation stations, and there was difficulty in adaptability with the variability of solar, wind, and DER. With the increasing adoption of these sources of energy, there has been an upgrade of the automated stations to adapt to the bidirectionality of flows, the variations in voltages, and the balancing of the load at a rapid rate of time. The latest technology allows adaptability and rapid adjustment in grid control with the generation of power. This reinforces that substation automation has become an essential milestone in the energy revolution for efficient integration of renewables into the grid.
