“…The time that elapses between the occurrence of fault and the fault clearing, just before the system becomes unstable, is defined as CCT [4]. In [5,6], CCT of grid connected induction generator was found by considering approximate steady state model. The steady state approximation of squirrel cage induction generator may not give accurate CCT as the transient behaviour of SCIG is neglected.…”

“…The distributed generators (DGs), especially based on renewable energies, are more and more present in distribution networks [1]- [11]. The increasing worldwide concern on environment-friendly and sustainable energy exploitation, and the consequent economical pressure posed by means of economical incentives are the main mechanisms that are driving towards a high penetration of renewable DGs (RDGs) [12]- [14]. Many issues arise from the introduction of DGs in the distribution network: power quality, power flow direction, nonintentional islanding, increased fault currents, protection discoordination, recloses operation, and so on [5]- [9], [13]- [22].…”

Techniques able to assess distribution networks reliability have to be adapted to the Smart Grid paradigm that is going to be implemented in real scenarios in the next future. In this perspective, an algorithm for distribution systems reliability assessment in the presence of distributed generators, accounting for islanding operation too, is presented in this paper. The procedures of the algorithm are the core of an analytical method and random/sequential Monte Carlo simulation methods developed by the authors in previous works. These methods are based on two elements: the first one is a generalized systematic approach able to identify the fault effect on a network's node thanks to some topological rules (called "cases") applicable to any radial network; the second one is a technique to faster compute reliability indices by aggregating faulted branches (called "set of branches") and nodes (called "set of nodes"). The paper proposes two automatic and general procedures to identify the cases and the sets, which are useful for implementation of both analytical and Monte Carlo simulation methods.

The diversification of the energy supply associated with the increasing interest in clean energy sources make most of the countries seek new technologies that could meet these needs. In this way, there has been a large increase in the number of wind turbines connected to the network. Considering the technological development and consequent increase in their capacity, the impact of wind turbines upon the network has been considered increasingly important for both steady state and dynamic conditions. In view of that, this paper will present a dynamic analysis of the impacts, especially electromechanical transients, caused by doubly-fed induction generator (DFIG) based wind turbines connected to the transmission electrical system.
