I’ve been a researcher in power electronics for a long time, mostly in grid applications like high-voltage DC (HVDC), flexible AC transmission systems (FACTS), distributed generation, and microgrids. Those are still active areas of research, but for me, the really interesting research questions right now are not about individual technologies but about the system challenge:…

The Federal Energy Regulatory Commission’s (FERC) Order 2222 has triggered a much-needed nationwide discourse on how to integrate distributed energy resources (DERs) into wholesale markets. At the same time, our efforts to value and compensate DERs for distribution-level benefits are barely scratching the surface, a gap that is severely constraining progress on decarbonization, resilience, and…

Evolving Electricity Supply and Demand Electrification of end uses and the decarbonization of electricity supply are among the key strategies in the broader transition to economy-wide decarbonization. Each one is rooted in separate parts of the energy system, but they are inherently linked. As electricity is increasingly used to meet energy demands within residential and…

The increasing percentage of distributed energy resources (DERs) brings a degree of uncertainty in bulk power system planning and operations. Additionally, it introduces an element of uncertainty with regard to distribution planning and operations, especially with regard to the dynamic behavior of DERs in juxtaposition with the behavior of induction motors. Legacy interconnection standards such…

If you follow ESIG conferences and webinars you will find some themes and ideas that run through many of the presentations: Power systems can operate reliably with high penetrations of variable energy sources. Certain ways of operating and planning power systems work well with renewables, and those ways are pretty different from the traditional industry…

The planet’s current energy system based on fossil fuel–derived energy has come with unwanted environmental impacts, largely driven by emissions that impact climate and local air and water quality. As society drives toward a cleaner, more sustainable energy system, the cost improvements and scale of wind and solar energy are enabling an economically viable transition…
