[ 1 ] - تاثیر فیلترهای اکتیو و پسیو در کاهش ولتاژ القایی شفت ژنراتورهای سنکرون با استفاده از کنترلر و مقایسه آنها

این مقاله بر روی کاهش ولتاژ القایی شفت با استفاده فیلترهای پسیو و اکتیو تمرکز نموده است. فیلتر پسیو از نوع RLC بوده و فیلتر اکتیو یک مبدل DC/DC باک کنترل شونده می باشد. فیلترهای پسیو و اکتیو در خروجی یکسوساز تریستوری قرار گرفته اند. از فیلترها به منظور کاهش پیک های فرکانس بالای ناشی از سوئیچینگ یکسوساز استفاده شده است. در سیستم تحریک استاتیک روشن و خاموش شدن تریستورها باعث ایجاد پیک های فرکانس ...

[ 2 ] - Feasibility study of presenting a dynamic stochastic model based on mixed integer second-order conic programming to solve optimal distribution network reconfiguration in the presence of resources and demand-side management

Nowadays, with the use of devices such as fossil distributed generation and renewable energy resources and energy storage systems that are operated at the level of distribution networks, the problem of optimal reconfiguration has faced major challenges, so any change in the power of this resources can have different results in reconfiguration. Similarly, load changes during the day can lead to ...

[ 3 ] - Stochastic Security Constrained Transmission and Battery Expansion Planning In Integrated Gas-Electricity Systems Considering High Penetration of Renewable Resources..

In this study, a new model is proposed to solve the problem of transmission and battery expansion planning considering integrated electricity and gas systems. The presented model is a bi-level stochastic planning model, where transmission and battery expansion planning modeling is done on one level, and gas network modeling is done on the other level. Here, the impact of the high penetration of...

[ 4 ] - Bi-Level Optimization of Microgrids Considering Electric Vehicles under the Worst Conditions of Renewable Resource Output

In this paper, a two-level optimization model of mixed quadratic integer programming (MIQP) is presented in order to optimally operate microgrids under worst-case output conditions of renewable energy sources. This two-level model is divided into two high-level and low-level problems. In the high-level problem, the goal is to reduce energy loss and load shedding in the demand response program, ...
