We give a protocol for Asynchronous Distributed Key Generation (A-DKG) that is optimally resilient (can withstand $${{\varvec{f}}}<\frac{{{\varvec{n}}}}{{{\varvec{3}}}}$$ faulty parties), has constant expected number of rounds, $${{\varvec{O}}}({\varvec{\lambda }} {{\varvec{n}}}^{{\varvec{3}}})$$ communication complexity, and assumes only the existence PKI. Prior to our work, best A-DKG protoco...

Development of distributed generations&rsquo; technology, trends in the use of these sources to improve some of the problems such as high losses, low reliability, low power quality and high costs in distributed networks. Choose the correct location to install and proper capacity of these sources, such as important things that must be considered in their use. Since distribution networks are actu...

due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. in order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. minimizing the losses in the system would bring two types of saving, in real life, one is ...

Generating a distributed key, where a constant fraction of the players can reconstruct the key, is an essential component of many largescale distributed computing tasks such as fully peer-to-peer computation and voting schemes. Previous solutions relied on a dedicated broadcast channel and had at least quadratic cost per player to handle a constant fraction of adversaries, which is not practica...

in this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. the objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. the combination of firefly algorithm, parti...

This paper presents two optimizations of the master-slave paradigm which provides more robustness. The former uses a mobile master which randomly jumps from node to node in order to dispatch the bandwidth load during the application execution. The latter aims to fully decentralize the paradigm like peer-to-peer systems. We present and experiment our new schemes on an application dedicated to te...

Conventional passive distribution networks are changing to modern active distribution networks which are not radial. Conventional load flow methods should be modified for new distribution networks analysis. In modern distribution networks distributed generation (DG) units are embedded with conventional and/or renewable resources. DG units are generally modeled as PV or PQ nodes which inject ...
