Abstract: Techniques are provided for implementing garbage collection and bin synchronization for a distributed storage architecture of worker nodes managing distributed storage composed of bins of blocks. As the distributed storage architecture scales out to accommodate more storage and worker nodes, garbage collection used to free unused blocks becomes unmanageable and slow. Accordingly garbage collection is improved by utilizing heuristics to dynamically speed up or down garbage collection and set sizes for subsets of a bin to process instead of the entire bin. This ensures that garbage collection does not use stale information about what blocks are in-use, and ensures garbage collection does not unduly impact client I/O processing or conversely falls behind on garbage collection. Garbage collection can be incorporated into a bin sync process to improve the efficiency of the bin sync process so that unused blocks are not needlessly copied by the bin sync process.

Abstract: A system for restoring an electrical distribution grid from cyber-physical attacks includes local controllers with grid-edge, inverter-based resource (IBR) field devices that collect IBR field device measurement data and compute power ratio deviations and regulate terminal voltages and system frequency of a respective IBR field device. IBR manager clients communicate with IBR local controller clusters and neighboring IBR manager clients and receive IBR field device measurement data and power ratio deviations and direct a selected local controller to adjust terminal voltage and system frequency within a connected IBR field device. A management server system implements a distributionally robust optimization (DRO) model and generates a sub-grid plan of terminal voltages and system frequencies for IBR manager clients and local controllers that minimizes expected load loss and compensates for power ratio deviations when subject to a cyber-physical attack.
