Allocation of DG in Distribution Network Using Parameter Independent JAYA Algorithm
Pandey Anand Kumar,Kirmani Sheeraz,Kumar Ankesh,Akhtar Iram 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.3
Integration of DGs in the distribution network has led to challenges in making the system reliability, and other parameters improve. This paper gives a detailed discussion on the placement of DG in the distribution system using the new algorithm ‘JAYA’ having no control parameter which makes the algorithm simple than previous used algorithms and also give best solutions according to the study. Three system parameters are considered for DG placement solution: active power loss reduction, voltage deviation reduction and voltage stability index maximization. The methodology is presented to calculate the optimal values for varying load profiles i.e. constant, residential, commercial and industrial. Type-1 DG placement is considered for placement. Simultaneous improvement of all factors using weight based multi-objective function is used. Standard test system IEEE-33 and 69 bus is used to validate the applicability of the methodology and compared to other optimization methods, the results presented proves the JAYA to be better optimization of optimal DG calculation as the method is simple, feasible and have good applicability with other nature inspired and meta-heuristic methods.
A curious case of a lost capsule: A rare case of small bowel diaphragm disease

Diaphragm disease (DD) is a rare condition that is associated with the use of nonsteroidal anti-inflammatory drugs. It is characterized by multiple diaphragm- like septa that cause a narrowing of the small bowel lumen. The diagnosis of this disorder can be challenging due to its rarity and its nonspecific symptoms, which often suggest other, more probable diseases. We report the case of a 16-year-old boy who presented with iron-deficiency anemia that did not respond to iron supplementation. Despite undergoing endoscopy and computed tomography (CT) enterography, the cause of his condition could not be identified. Capsule endoscopy was attempted, but due to technical difficulties, images could not be obtained. Two years later, the patient's symptoms persisted, prompting further investigation. CT enterography revealed a foreign body in the distal ileum, which was identified as the previously administered capsule. Diagnostic laparoscopy with intraoperative endoscopy was performed to retrieve the capsule. This procedure also revealed multiple short-segment strictures causing luminal narrowing and ulcerations. These were confirmed by histopathology to be lesions associated with DD.
