Protecting the solar energy grid from cyberattacks

A long term driven by renewables promises sustainable strength and a cleaner environment – but that doesn’t suggest it’s with out threats. Incorporating further factors of era these types of as photo voltaic farms can inadvertently introduce soft entry factors for cyber hackers in search of to exploit weaknesses in the nation’s electricity grid.

That is why Jin Ye and WenZhan Tune, professors in the College of Georgia College of Engineering, are doing work with a consortium of partners from the general public and private sectors to shore up the country’s electricity grid’s defenses.

Utilizing a $three.6 million grant from the U.S. Office of Electrical power Photo voltaic Electrical power Technologies Office environment, Ye and Tune is section of a multilevel cyber protection task that aims to safely combine photo voltaic electricity systems into the grid. The College of Arkansas is the direct institution on the task when the College of Georgia is the 2nd-premier receiver of the funding.

Ye, an assistant professor, and Tune, the Georgia Electrical power Mickey A. Brown Professor in Engineering, will acquire improved cybersecurity systems at two vital junctures – the photo voltaic PV inverter which connects photo voltaic electricity models to the grid, as very well as the broader technique itself. They intend to craft algorithms and use a equipment mastering-dependent hybrid intrusion detection technique to better guard photo voltaic technologies from attacks. This two-stage solution to shielding the grid adds a layer of security, when also firming up a person of the extra susceptible ports of assault, the social PV inverter itself.

“For photo voltaic strength, there is an amplified penetration of PV systems into the current market, and the electricity grid is increasing extra dependent on them,” Tune reported. “It is much a lot easier to assault photo voltaic systems, which are more and more deployed almost everywhere, instead than assault a centralized electricity generator, which is extra securely guarded as a vital facility.”

The scientists want to create a new framework for the inverters exactly where various security abilities, these types of as source chain security and firmware safety, can be utilized. In addition, complementary technique security techniques will make use of on a regular basis readily available knowledge from photo voltaic farms and other era amenities to fortify security measures.

“Across the various partners, every single researcher is in charge of his or her own components of the task, when doing work with each other to make confident items combine in the end,” reported Ye.
