Whenever new applied sciences are launched into the ability grid, there’s all the time an opportunity they may disrupt the system, presumably even resulting in blackouts.
Finding methods to cope with the affect on the grid brought on by incorporating renewable power has been the main focus of
Vijay Vittal’s analysis for almost 20 years. He is a professor of energy methods engineering within the Fulton program at Arizona State University, in Tempe.
The IEEE Life Fellow is credited with figuring out how finest to isolate elements of the ability grid to stop your complete grid from happening.
He was a part of an IEEE process pressure that in 2020 issued a
report that described how tools used for storing power, transferring energy over lengthy distances, and integrating renewable power might affect energy system stability. The report really helpful methods to characterize and outline the issue.

An
article he cowrote that was primarily based on the report obtained a 2022 IEEE Power & Energy Society Prize Paper Award.
The award was “a welcome surprise,” he says, although “we thought the document turned out very well.”
From synchronous machines to quick response energy electronics
That article was an replace of a 2004
article that Vittal coauthored as a member of a joint process pressure fashioned by the IEEE Power & Energy Society and CIGRE, a world affiliation of energy system professionals, headquartered in Paris.
“
Definition and Classification of Power System Stability” addressed methods that, on the time, had been dominated by synchronous machines—motors and turbines—and their controls. By 2016, fast-acting energy electronics had been being launched to the grid, and their traits differed from the rotating machines used almost a decade earlier than.
“These issues required a reevaluation of how we had defined and classified stability in 2004,” Vittal says.
He and others from the
PES energy system dynamic efficiency committee and the CIGRE Council of Large Systems’ research committee fashioned a process pressure in 2016 to replace the 2004 doc.
In “
Definition and Classification of Power System Stability: Revisited and Extended,” the committee famous that converter-interfaced technology know-how and cargo and transmission gadgets had been more and more being built-in, inflicting the dynamic response of energy methods to turn out to be extra depending on advanced fast-response energy digital gadgets. The gadgets embrace electrochemical storage options, high-voltage direct-current strains for transferring energy over lengthy distances, versatile alternating-current transmission system gadgets to assist stabilize the grid, and energy digital converter interfaces that combine renewable power.
“The synchronous machine has one big advantage,” Vittal says. “It has this pure means to supply assist when it comes to the kinetic power of the inertia, whereas wind generators and photovoltaic photo voltaic methods don’t inherently have that functionality.
“Renewable systems don’t have the inertia in their systems to keep things spinning. This creates a whole new set of stability issues, performance issues, and characteristics that were not seen in the system when it was primarily dominated by synchronous generators.”
Vijay Vittal receives the 2018 Kundur Power System Dynamics and Control Award from then president of the IEEE Power & Energy Society, Saifur Rahman.PES
New instruments and extra engineers
The integration of recent applied sciences into the grid isn’t the one subject, Vittal says. Also wanted, he says, are higher analytical instruments and extra energy engineers.
The electrical grids within the United States and in Europe are interconnected, he says, and planning and working them requires new instruments.
“The computational problem of handling these large systems is enormous,” he says. “We need efficient computational techniques.”
Today’s deterministic evaluation exhibits solely whether or not an influence system is tolerant to recognized faults and hazards and is safely working. Vittal says probabilistic instruments must be developed to supply extra lifelike danger estimates.
Another concern he has is a pending labor scarcity.
“Several engineers who have a tremendous amount of experience and an excellent feel for how the systems work are either close to retiring or have retired,” he says. “There is this system memory that is fast disappearing.”
An early curiosity in energy engineering
Power engineering runs in Vittal’s household. His maternal grandfather was chief engineer at a hydroelectric station in Karnataka, India, the place Vittal grew up. While pursuing a bachelor’s diploma in electrical engineering on the
B.M.S. College of Engineering, in Bangalore, Vittal took an elective course on energy system evaluation. It piqued his curiosity in energy engineering.
Two years after graduating in 1977, he earned a grasp’s diploma in EE on the
Indian Institute of Technology, Kanpur. He was impressed to work on energy system stability points by an advisor conducting analysis within the space.
Vittal moved to the United States to pursue a Ph.D. in EE at
Iowa State University, in Ames. After he graduated in 1982, he accepted a place on the college as a school member. He taught energy engineering there for 22 years, with a break in 1993 and 1994 to function energy methods program director for the U.S. National Science Foundation’s Division of Electrical and Communication Systems, in Washington, D.C. The NSF acknowledged him in 1985 with its Presidential Young Investigator Award.
He left Iowa State in 2005 to hitch Arizona State, the place he has served as director of its
Power Systems Engineering Research Center. In 2019 he was named a regents professor, the very best school place.
He says he has by no means been taken with getting a job in trade.
“I like working with students,” he says. “Working with young people recharges my batteries.”
