Reliability Value of Long-Duration Energy Storage against Extreme Events in High-Renewable Grids: A Full-Year AC-OPF Assessment
Jeongdong Kim, Jonggeol Na, Sungho Shin
Long-duration energy storage (LDES) can mitigate prolonged renewable--load imbalances during Dunkelflaute events, but existing studies rely on zonal or linearized DC network models…
Watts vs. Bytes: Turning Data Centers into Grid Assets via Storage Compute Co-Optimization
Shaohui Liu, Sungho Shin, Deepjyoti Deka
Data center interconnections increasingly face tighter peak-demand and ramp-rate limits while being expected to support grid operations. Satisfying these requirements calls for coo…
Approximate Dynamic Programming for Degradation-aware Market Participation of Battery Energy Storage Systems: Bridging Market and Degradation Timescales
Flemming Holtorf, Sungho Shin
We present an approximate dynamic programming framework for designing degradation-aware market participation policies for battery energy storage systems. The approach employs a tai…
