The design and operation of distributed energy systems in under fundamental changes due to new opportunities and looming challenges. On one hand, the proliferation of distributed energy resources (DERs) and the emergence of new business models offer novel means to enhance resiliency of distributed systems. On the other hand, climate change is likely to induce more frequent and severe extreme weather events, thus compromising resiliency and low-carbon targets of the energy systems. I collaboratively develop a new analytical framework that integrates the planning of DERs and demand response (DR) programs for improving the resiliency of renewables-dominant power systems in the face of extreme events.
