Distributed generation resources (DGRs), such as solar on our roofs and battery storage devices in our garages, can help lower the cost of electricity and increase consumer choice, while providing clean, local energy. As DGRs become more common, it’s crucial to understand their effects on both local and regional grids. This helps planners better navigate…

Is anyone else suffering from “The Baader-Meinhof Phenomenon” where now that I’m seeing lots of commercials about electric vehicles (EVs), it feels like they are everywhere? It’s the same phenomenon that applied on those road trips as a kid where you looked for blue cars and they suddenly appeared. While walking my dog, Wallie, the…

As the global energy landscape rapidly shifts towards renewable energy sources, ensuring the stability and reliability of power systems has become more complex and critical than ever before. One of the key components in this evolving grid architecture is the grid-forming inverter-based resource. These grid-forming inverters (GFMIs), unlike traditional grid-following inverters, are designed to “form”…

  U.S. Interconnection Queues Have Unprecedented Amounts of Renewable Energy and Storage Grid interconnection, the process of connecting generators or energy storage to the electric grid, has emerged as a significant obstacle to the energy transition in the United States. From 2000 to 2010, the U.S. averaged between 500 to 1,000 new annual transmission interconnection…

For long-term transmission planning, the topology of the existing transmission grid is typically assumed to be fixed, and not a decision variable. But this may be about to change in the U.S. with FERC Order 1920, which requires consideration of transmission switching among other technologies. Using transmission switching as a decision variable can provide significant…
