The power generations in modern times are becoming increasingly dynamic as there are increasingly diverse power sources, which makes the grid react to the unpredictable generation of power. It can be avoided by using digital substations, which utilize the digital for energy conversion.
Digital Substation Market Dynamics and Trends
The low cost of ownership majorly drives the global digital substation market through asset monitoring and optimized grid operation, with increased system awareness and proactive monitoring of demand, thereby making the system more resilient. Moreover, other factors such as reduced engineering work improved the safety of the workforce, and easier & faster testing and commissioning are some driving factors for the market in the upcoming years.
Reduction in operational cost and initial investment
Commissioning a digital substation reduces operational costs, which aids in the market’s growth during the forecast period. For instance, a digital substation reduces the use of copper signal cable, which directly impacts the investment needed to set up a digital substation. It is fitted with fiber optic cables instead of copper wires, reducing the carbon footprint by 50% and resulting in a lower impact on the environment.
The room size is 30% less than the conventional substation, positively impacting the digital substation's operational costs. Additionally, the prevalence of IIoT (Industrial Internet of Things), specifically in energy sectors, leads to the adoption of smart grid components, enhancing operational ability as they are more reliable and sustainable. Thus, it helps obtain a longer system life cycle and optimal use of resources coupled with higher efficiency.
Increased safety and cybersecurity during the implementation of digital substation
The growing need to implement a high-security transmission network is a major driving factor for the market in the upcoming years. The implementation of a digital substation protects the workforce from the high voltage equipment and wires as they are now digitalized, and the use of the optic fibers eliminates the electrical connection between high voltage equipment and protection and control equipment which thereby reduces the risk of electrocution and increasing the safety of the personnel. Furthermore, cybersecurity issues such as cyber-attack from external systems are a major threat in many countries across the globe, a fully optimized digital substation integration of systems without having any devastating effect on security issues across its communication network.
Lack of skilled labor hampers the growth of the market
Due to the paradigm shift from traditional substations to digital substations, the technology requires a skilled labor force that might go beyond IEC 61850 standard. It also requires strong domain knowledge of network infrastructure, cyber security, and other technologies involved in using the digital substation. Furthermore, a digital substation requires frequent maintenance to maintain the substation working for a long period.
Digital Substation Market Segment and Shares Analysis
The global digital substation market is segmented on module, usage, voltage, end-user, and region.
Need to replace the old aging system of the conventional energy distributions system to augment the growth of the market during the forecast period
The global digital substation market is bifurcated into hardware, fiber optic communications network, and SCADA (Supervisory Control and Data Acquisition). Out of the mentioned list, hardware is the largest segment in terms of revenue. However, the fiber optic communications network is expected to witness the highest growth rate during the forecast period.
The hardware segment includes various components such as transformers, earth devices, isolators, bus bars, protection devices, and interfacing units. Transformers are the most crucial part of the hardware segment. They are primarily deployed in the substation to lower voltage from high to low to be delivered in either overhead or underground line to the customer. Various new technologies are used in the transformer to evolve the distribution system process, and the latest technology is an optical transformer. The optical transformers use optical sensors to realize the current and voltage in the high-voltage substation line. Thus, the ongoing development of the transformer to make it technologically advanced and developed is having a positive impact on the segment's growth during the forecast period.
