The demand for low voltage DC (LVDC) distribution systems is increasing due to the rapid development of power conversion technology, increase DC-based digital loads, and expansion distributed generation (DG). For stable operation LVDC system, it necessary develop a protection method. In this paper, fault section estimated using wavelet transform (WT) in system. classified into line bus. charact...

Fault detection and isolation are important tasks to improve the protection system of low voltage direct current (LVDC) networks. Nowadays, there challenges related strategies in LVDC systems. In this paper, two proposed methods for fault faulty segment through line bus measurement were discussed. The impacts grid characteristics protective devices under pre-fault normal, under-fault, post-faul...

Low-voltage (LV) and high-voltage (HV) DC distribution systems are being investigated as alternatives due to the growth of energy resources (DER), loads such solar wind power systems, storage sources (ESSs). Furthermore, an HV/LV system offers various advantages, including lower conversion losses, easier connecting strategy for DERs, less complex management techniques. As renewable increasingly...

This paper presents an in-depth comparison of the benefits and limitations using a low-voltage DC (LVDC) microgrid versus AC with regard to integration low-carbon technologies. To this end, novel approach for charging electric vehicles (EVs) on distribution networks by utilizing LVDC backbone is discussed. The global aim conducted study investigate overall energy losses as well voltage stabilit...

در میان شبکۀ معابر شهری، راه‌های اضطراری امدادرسانی حین زلزله، به‌ویژه مرحلۀ پاسخ به بحران، نقش مهمی ایفا می‌کنند. حفظ عملکرد این شبکه از معابر، ساعات اولیۀ پس اهمیت بسزایی دارد. محافظت و مقاوم‌سازی اجزای آسیب‌پذیر شبکه، به‌خصوص پل‌ها، پیش وقوع تأثیر شایان توجهی کاهش خسارات آسیب‌ها اغلب اوقات تمامی آسیب‌پذیر، به‌دلیل محدودیت بودجه، عملاً ناممکن است. ایجاب می‌کند که با شناسایی دقیق گزینه‌های ابتد...

The main objective pursued by this survey is to debate the feasibility of a new distribution system in low voltage direct current (LVDC) microgrids and its impact on social development. To end, study provides valuable information for renewable energy planners researchers, giving insights or solutions reduce transition gap between network future DC microgrids. Mainly, article divided into interl...

Low-voltage direct current (LVDC) systems have been increasingly studied as new efficient power systems. However, existing studies primarily focused on conversion designs, control, and operation, research ground configurations of LVDC systemsis insufficient. Consideration the installation criteria protective equipment grounding is crucial because in general households for end users are highly a...
