Delivery Reliability Optimalization in Distribution Systems with Backup Coverage

An Evaluation of the Systems Reliability Using Fuzzy Lifetime Distribution

coordination of protective schemes in distribution and subtransmission systems including distributed generation

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...

Reliability Analysis of Fault Tolerant Systems with Multi- Fault Coverage

Fault-tolerance has been an essential architectural attribute for achieving high reliability in many critical applications of digital systems. Automatic fault and error handling mechanisms play a crucial role in implementing fault tolerance because an uncovered (undetected) fault may lead to a system or a subsystem failure even when adequate redundancy exists. Examples of this effect can be fou...

Analyses of delivery reliability in power systems

This paper describes a newly developed method for analyzing reliability in complex systems such as electrical power systems. The method is based on splitting up Markov models into smaller unit models, thus enabling building large, complex models and analyzing them as a unit but with the original level of details. Traditionally, such analyses have been made using simple models to fit the system ...

Reliability Assessment of Distribution Systems in Presence of Microgrids Considering Uncertainty in Generation and Load Demand

The microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. Normally, microgrids contain renewable-energy-based Distributed Generation (DG) units, which their output power varies with different environmental conditions. In addition, load demand usually changes with factors such as hourly and seasonal customer activities. Hence, these issues hav...
