The Federal Energy Regulatory Commission (FERC) issued “new mandatory standards for inverter-based resources (IBRs) in an effort to enhance the reliability of the bulk electric system. IBRs are solar photovoltaic, wind, fuel cell and battery storage resources that use power electronic devices to change direct current power to alternating current power, to be transmitted on the bulk-power system.
In its November 17 action orders, FERC focused on three IBR-relateded actions:
- An order directing the North American Electric Reliability Corp. (NERC) to develop a plan to register the entities that own and operate IBRs;
- A Notice of Proposed Rulemaking to direct NERC to develop reliability standards for IBRs that cover data sharing, model validation, planning and operational studies, and performance requirements; and
- An order approving reliability standards that are related to IBRs, which NERC proposed earlier in 2022.”

“The $52 billion spending plan outlined in the CHIPS and Science Act that has been signed into law has significant implications for the semiconductor ecosystem—from chip manufacturers to engineers and production teams.
EE Times asked two design engineers to weigh in on the implications of the Act for engineers in the U.S., in the short and long term. Will it simply help return the design engineering process to status quo pre-2020? Or are there greater changes afoot that will drive a significant shakeup of the semiconductor design and manufacturing process? The answer lies somewhere in between.”
PowerMag – The case for advanced analytics and remote diagnostics: During the last 25 years significant advancements have been made in remote monitoring capabilities for power plants. A number of operations and maintenance (O&M) functions can routinely be managed remotely, and it is also becoming more common for peaking and renewable energy plants to be remotely operated reliably and safely.
Operating and maintaining a full-scale power plant remotely presents challenges that require sophisticated systems, reliable sensor and diagnostic equipment, stable high-bandwidth communication, and advanced security protocols. Even with progress made in each of these areas, some plant managers don’t foresee a scenario where remote operations will become the norm. But even in cases where there are no plans to run a generating station from a remote location, there is still a solid case for adopting remote technology.
Here are five reasons why the case for remote technology is stronger today than ever before.

Science News and Carnegie Mellon University – Many natural organisms have the ability to repair themselves. Now, manufactured machines will be able to mimic this property. In findings published this week in Nature Materials, researchers at Carnegie Mellon University have created a self-healing material that spontaneously repairs itself under extreme mechanical damage.
This soft-matter composite material is composed of liquid metal droplets suspended in a soft elastomer. When damaged, the droplets rupture to form new connections with neighboring droplets and reroute electrical signals without interruption. Circuits produced with conductive traces of this material remain fully and continuously operational when severed, punctured, or had material removed.
Applications for its use include bio-inspired robotics, human-machine interaction, and wearable computing. Because the material also exhibits high electrical conductivity that does not change when stretched, it is ideal for use in power and data transmission.
All About Circuits – As the pandemic resurges in many parts of the world, researchers have found a way to bring the speed and accuracy of infection testing to mobile devices with a lab-on-a-chip.
A new lab-on-a-chip has been developed by researchers at Imperial College London who hope it can pave the way for low-cost portable diagnostic testing. The lab-on-a-chip (LoC) technology, known as TriSilix, is a “micro laboratory” that can reportedly perform a scaled-down version of the polymerase chain reaction (PCR) test on the spot, presenting its results in just a few minutes. PCR, which detects viruses and bacteria in biological samples, is usually performed in a laboratory, meaning that test results don’t become immediately available.
Each LoC device contains a DNA sensor, temperature detector, and heater so that the testing process can be automated. According to the researchers’ published findings in Nature Communications, a standard smartphone battery is capable of powering up to 35 tests on a single charge.
