Auction-Based Scheduling of Excess Energy Consumption to Enhance Grid Upward Flexibility

Ahmed Abada, Marc St-Hilaire, Wei Shi
2021 IEEE Access  
Existing datacenter-based grid balancing approaches have focused on providing downward flexibility and only considered the case of owner-operated datacenters.  ...  In contrast, our system focuses on providing upward flexibility to target the increasingly frequent problem of excess energy from renewables, and it uses public cloud datacenters to increase the participation  ...  As future work, we are planning several enhancements to the system model, such as including the cost of migration, maximizing the sale revenue of the auction, and targeting NP-hard complexity of the system  ...
