Managing uncertainty has always been a central part of electric grid operations, but today’s risks to reliable operations look very different than just a few years ago. Understanding and addressing these risks is vital to meeting our reliability imperative—a responsibility shared by grid operators, utilities, and states to ensure reliability of the electricity system. Over…

At a concert, a band member may break off into a solo to captivate the audience. However, it is the other side of the solo that sets the best bands apart: orchestrating the return of the soloist back to playing as a full band in perfect harmony. The same can be said about the two…

Until recently, practical applications of grid-forming (GFM) inverters were limited to micro and isolated grids and in smaller grid applications on the order of a few tens of megawatts. Over the past 12 months, the landscape has changed rapidly, with more than ten projects on the order of several hundred megawatts being developed worldwide for…

Introduction Let’s face it, accurate and reality-based modeling of the dynamic performance of inverter-based resources is not easy. The quality of the analysis performed, and thus the reliability of the bulk power system (BPS), depends on the accuracy, fidelity, and appropriate parameterization of the models used. The first step to improving inverter-based resource model accuracy…

Power system operators around the world are pushing the limits of integrating inverter-interfaced generation from wind and solar to very high levels approaching 100%, including in South Australia, Ireland, the Hawaiian Islands, and Great Britain. These and several others have identified the value of grid-forming (GFM) technology as the key enabler to support this transition.…

  New England is in the midst of a radical transformation in how the region consumes and produces electricity. Decarbonizing the economy means residents will rely on the electric grid to charge their vehicles and heat their homes and businesses—and it means clean, renewable resources must supply that power. New England’s clean energy transition has…

We have reached a key moment in the energy transition. Regulators, system operators, standardization bodies, and research institutions have reached consensus that a decarbonized system will necessarily consist of inverter-based resources (IBRs) and that an inverter-based system needs grid-forming (GFM ) technology to be stable. In line with this understanding, there has been significant development…

An estimated 427 GW of battery storage capacity was in the interconnection queues around the U.S. as of the end of 2021. In the absence of any incentives or requirements for more advanced control capabilities, all of these resources are being planned with conventional grid-following (GFL) controls. Some of these batteries will be built in…

While much of Washington and the energy policy community spent this year preoccupied with the vicissitudes of the Inflation Reduction Act (IRA), pending actions at the Federal Energy Regulatory Commission (FERC) will determine whether the IRA’s 10-year extension of clean energy tax credits can successfully drive the nation towards decarbonization. With Senator Manchin’s energy permitting…

Introduction The process for connecting large generators to the bulk electric system in the United States (U.S.) was designed in the early 2000’s. For about a decade, wind and natural gas resources had the largest share in the interconnection queues and have since then grown into mature technologies, with sophisticated plants designed by experienced engineers.…
