The ongoing struggle to keep the US electric grid safe from attacks can seem like a losing proposition, especially given recent reports of Russian-sponsored hacking attempts and a serious warning about increasing vulnerability. However, there are quieter accounts of progress among those working to keep the grid safe.
Berkeley Lab Threat Detection Tool
One is a 3-year project led by Berkeley Lab researchers and supported by several key partners that features a new tool to detect cyber-physical attacks. The researchers designed a new architecture that combines a micro phasor measurement unit (μPMU) that captures data about the grid’s physical state with information from commonly used SCADA monitoring systems. Together, the combined data provides real-time feedback about grid performance through a redundant set of measurements with high fidelity. The idea is to bridge the gap between the physical world and the cyber world and find discrepancies that could indicate certain types of attacks are underway against grid components.
The Department of Energy (DOE) supported Berkeley Lab project is moving to the technology transfer stage, with the team preparing a final report and meeting with industry stakeholders to introduce them to this novel security framework. Partners on the project included EnerNex, EPRI, Riverside Public Utilities, and Southern Company.
Insurance Model to Protect the Grid?
In what seems like a stretch, two University of Wisconsin-Milwaukee researchers are investigating the potential of a new insurance model aimed at motivating utilities and regulators to invest more in cybersecurity assets. The idea is to support utilities implementing high cybersecurity tools with lower insurance premiums, and to penalize those with low cybersecurity processes with higher premiums. The two have funding from the National Science Foundation to build predictive models in a project that blends several disciplines, including electrical engineering, computer science, actuarial science, and statistics. More to come on this front, for sure.
Going Retro for Grid Security?
Meanwhile, there is a move in Congress to support older style tools to help safeguard the grid. The retro effort comes in the form of a senate bill that, if passed, would direct the national laboratories to partner with private companies to identify analog approaches that do not rely on digital infrastructure or tools. According to senators supporting the bill, the idea springs from the 2015 cyber attack on Ukraine’s energy grid in which operators restored power relatively quickly using human-powered or analog systems instead of digital. The bill is not without critics, one of whom claims it is a mistake to look backward for answers such as the ones proposed, though he applauds the focus being placed on enhanced security.
So the Grid Could Be Okay?
The takeaway from these disparate and under-the-radar efforts should be a sense of calm that not all is doom and gloom when it comes to grid security. The grid might be tougher than you think. The good guys are working on new solutions, too (be sure to check out Navigant Research’s recent report, Managing IoT Cybersecurity Threats in the Energy Cloud Ecosystem). Some solutions might have limited effects, like going retro, but there is hope future attacks will be countered with robust defenses that thwart attacks and keep the grid safe.
Power Standards Lab μPMU
Note: Developed at Power Standards Lab under a project led by Berkeley Lab and funded by DOE’s ARPA-E program, µPMUs are designed to increase situational awareness at the power distribution grid level.
