Almulla S. | Hawashin D. | Al Shab M.

Abstract: Digital substations are the next generation of power substations that influences modern digital technology to transform the way electricity is transmitted and distributed. It is transforming the electrical power systems industry, implementing advanced technologies such as the IEC 61850 standard and Ethernet communication, offering a wide range of benefits such as enhanced reliability, reduced maintenance costs, and improved efficiency. This paper provides a comprehensive overview of digital substations covering their definition and levels. In addition, real-world case will be addressed as an example of implementing digital substations. The paper also explores the opportunities associated with the implementation of digital substations in real-world case studies. However, the implementation of digital substations also poses challenges that must be addressed to realize the full potential of this technology. Overall, digital substations represent a significant shift in the power industry towards a more advanced, intelligent, and sustainable future.
