Dr. Kezunovic gave a presentation at PSERC, which is available at T&D Webinars. The title of the seminar is “Interoperability Requirements as an Enabler of Smart Grid Integrative Research” and it can be accessed online: [webinar] [slides]. More information is available at PSERC T&D Webinars page.

Interoperability and role of the relevant standards

Dr. Kezunovic just published an article in Electric Perspectives magazine from EEI:

Depending on the utility’s needs, there are four different design approaches to the substations of the future.

The electricity grid was invented in the 19th century and greatly expanded in the 20th. Recognizing the grid’s complexity and relevance, the National Academy of Sciences declared the electricity system the world’s largest “machine” and placed it at the top of the list of the greatest engineering achievements of the 20th century. The challenge facing electricity systems in future is to maintain the reliable and safe operation of this ever-expanding but already complex machine.

Technological, economic, and societal needs have driven most electricity system developments. And recently, a large emphasis has been placed on the use of renewable energy resources and the electrification of transportation, both affecting future development of the grid. As a result, grid expansion is needed, but the reliability and safety challenges in an interconnected world expand as well. This concern was highlighted over the last decade by several widespread power system failures that had an enormous impact on the economy and livelihoods in both developed and undeveloped countries. Read the entire article.
