Power Control Center Applications using Highly Available Distributed RAM (HADRAM)

With on-going deregulation, with tighter interdependence between energy providers, and with growing demands on reliability, Power Control Centers (PCC) need to both scale up and to allow access to comprehensive real-time data. In this paper, we propose to build PCCs based on geographically distributed and tightly coupled clusters of heterogeneous computer clusters. Our proposal, Highly Available Distributed Random Access Memory (HADRAM), and Distributed Linear Hashing with scalable availability (LH*RS) uses the distributed memory in the cluster to store all data, with redundancy needed for recovery in case of data loss. This approach allows very fast fail-over, but also lends itself to remote data accesses.
