Bayesian Networks Application to Reliability Evaluation of Distribution Systems Containing Micro-Grids or Looped Network

A Bi-Level Optimization Approach for Optimal Operation of Distribution Networks with Retailers and Micro-grids

Distributed energy resources (DERs) including distributed generators (DGs) and controllable loads (CLs) are managed in the form of several microgrids (MGs) in active distributions networks (ADNs) to meet the demand locally. On the other hand, some loads of distribution networks (DNs) can be supplied by retailers which participate in wholesale energy markets. Therefore, there are several decisio...

An Evaluation of the Systems Reliability Using Fuzzy Lifetime Distribution

Application of cut set method to reliability evaluation of mine ventilation networks

Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...

Optimal Self-healing of Smart Distribution Grids Based on Spanning Trees to Improve System Reliability

In this paper, a self-healing approach for smart distribution network is presented based on Graph theory and cut sets. In the proposed Graph theory based approach, the upstream grid and all the existing microgrids are modeled as a common node after fault occurrence. Thereafter, the maneuvering lines which are in the cut sets are selected as the recovery path for alternatives networks by making ...

Application of Bayesian Networks to Reliability Evaluation of Software System for Subsea Blowout Preventers

The work develops a redundant software system for subsea blowout preventers, including control logics, human-machine interface (HMI) programs, remote access and redundant databases in order to meet the high reliability requirement of subsea drilling. The Bayesian networks (BN) for control logics, HMI programs and redundant databases are built and then the whole BN are established. The quantitat...
