F. Babaei; A. Safari; J. Salehi; H. Shayeghi

Articles in Press, Corrected Proof, Available Online from 28 December 2023


  Although the presence of clean energy resources in power systems is required to reduce greenhouse gas emissions, system security faces severe challenges due to its increased intelligence and expansion, as well as the high penetration of renewable energy resources. According to new operating policies, ...  Read More

Co-Evolutionary Multi-Swarm PSO Based Optimal Placement of Miscellaneous ‎DGs in a Real Electricity Grids Regarding Uncertainties

G. Derakhshan; H. Shahsavari; A. Safari

Volume 10, Issue 1 , April 2022, , Pages 71-79


  Distributed generators (DGs) facilitate minimizing a monetary objective for controlling overload or low-voltage obstacles. In conjunction with controlling such complications, a DG unit can be allocated for maximum reliability or efficiency. This study presents a new method based on a new index for locating ...  Read More

A Bi-Level Optimization Approach for Optimal Operation of Distribution Networks with Retailers and Micro-grids

H. Fateh; A. Safari; S. Bahramara

Volume 8, Issue 1 , February 2020, , Pages 15-21


  Distributed energy resources (DERs) including distributed generators (DGs) and controllable loads (CLs) are managed in the form of several microgrids (MGs) in active distributions networks (ADNs) to meet the demand locally. On the other hand, some loads of distribution networks (DNs) can be supplied ...  Read More

SCA based Fractional-order PID Controller Considering Delayed EV Aggregators

F. Babaei; A. Safari

Volume 8, Issue 1 , February 2020, , Pages 75-85


  The EVs battery has the ability to enhance the balance between the load demand and power generation units. The EV aggregators to manage the random behaviour of EV owners and increasing EVs participation in the ancillary services market are employed. The presence of aggregators could lead to time-varying ...  Read More
