R. Behkam; A. Moradzadeh; H. Karami; M.S. Nadery; B. Mohammadi ivatloo; G.B. Gharehpetian; S. Tenbohlen

Volume 11, Issue 1 , April 2023, , Pages 11-21


  The Frequency Response Analysis (FRA) technique has advantages in identifying faults related to power transformers, but it suffers from the interpretation of frequency responses. This paper presents an approach based on statistical indices and Artificial Neural Network (ANN) methods to interpret frequency ...  Read More

Micro Grid
A Repetitive Control- Based Approach for Power Sharing Among Boost Converters in DC Microgrids

M. Zolfaghari; G. B. Gharehpetian; M. Abedi

Volume 7, Issue 2 , October 2019, , Pages 168-175


  In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller ...  Read More

Micro Grid
Control of Inverter-Interfaced Distributed Generation Units for Voltage and Current Harmonics Compensation in Grid-Connected Microgrids

Reza Ghanizadeh; Mahmoud Ebadian; Gevork B. Gharehpetian

Volume 4, Issue 1 , June 2016, , Pages 66-82

  In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC voltage harmonics. In absence of sensitive loads at PCC, ...  Read More
