This paper investigates a Solid State Transformer (SST) based DC microgrid architecture, addressing the design and control of the multiple SST power conversion stages and the power management strategy required for its integration with other microgrid elements, such as storage devices and local distributed generation. The advantages of a SST in relation to conventional low frequency transformers are...
Reliable broadcast protocol is a fundamental buildingblock in fault-tolerant distributed systems. It consists of a basicprimitive that provides agreement among processes of the system on the delivery of each broadcast message, i.e., either none or all correct processes deliver the message, despite failures of processes. In this work, we propose a reliable broadcast solution on top of the VCube, assuming...
A quorum system is a collection of process sets (quorums) which intersect among themselves. Quorums are used by many distributed applications such as mutual exclusion, data replication, and for the dissemination of information. This work presents an autonomic solution to build a majority quorum system that is self-adaptive by dymically reconfiguring itself if processes fail. Processes can fail by...
This paper describes a new resonant converter topology, using a solid-state asymmetric bridge to increase the energy efficiency of the solid-state switching circuit being designed to replace the actual pulse transformer and thyratron based resonant modulator that supplies the 60 kV target potential for the ion acceleration of the On-Line Isotope Mass Separator ISOLDE accelerator. The preliminary results...
This paper presents an autonomic algorithm for constructing minimum spanning trees in a distributed system. Processes are virtually organized on a hypercube-like topology, called VCube. The spanning trees are dynamically created from any source process and regenerated transparently when processes become faulty. Any tree reconstruction is autonomously done based on the virtual topology and on fault...
Distributed mutual exclusion is a basic building block of distributed systems that coordinates the access to critical shared resources. This work introduces a novel permission-based k-mutual exclusion algorithm for distributed systems with crash faults. Processes monitor each other and organize themselves on an adaptive virtual topology that is based on the hypercube and presents several logarithmic...
