Distribution systems are the major interface between electricity consumer and electrical transmission system. Requisite amount of planning is necessary for these to be in order as they vast complex. An important concern on operation distribution its voltage stability. Placing Distributed Generation (DGs) system can address concerns a better way. The location rating DGs going have deep impact pr...

For over a decade, distributed generations (DGs) have sufficiently convinced the researchers that they are economic and environment-friendly solution can be integrated with centralized generations. The optimal planning of requires appropriate location sizing their corresponding control various power network types to obtain best technical, economical, commercial, regulatory objectives. Most thes...

This paper aims to address the combination of distributed generation placement and dynamic distribution network reconfiguration. Herein, a multi-strategy multi-objective improved black widow algorithm is proposed. A model established, which considers objectives minimizing active power loss, voltage deviation, carbon emission. The proposed significantly enhances traversal capability search speed...

Along with economic growth of countries which leads to their increased energy requirements,the problem of power quality and reliability of the networks have been more considered andin recent decades, we witnessed a noticeable growing trend of distributed generation sources(DG) in distribution networks. Occurrence of DG in distribution systems, in addition tochanging the utilization of these sys...

These days randomized-based population optimization algorithms are in wide use in different branches of science such as bioinformatics, chemical physics andpower engineering. An important group of these algorithms is inspired by physical processes or entities’ behavior. A new approach of applying optimization-based social relationships among the members of a community is investigated in this pa...

OBJECTIVE To compare speech performance and levels of oral impairment between two types of lingual brackets. METHODS A parallel-group randomized controlled trial was carried out on patients with Class II, Division 1 malocclusion treated at the University of Hama School of Dentistry in Hama, Syria. A total of 46 participants (mean age: 22.3 ± 2.3 years) with maxillary dentoalveolar protrusion ...
