A simplified static frequency converter model for electromechanical transient stability studies of 16 Hz railways
John Laury, Lars Abrahamsson, Math H. J Bollen
With increased share of Static Frequency Converters (SFCs) in 16 Hz railway grids concerns about stability have increased. Stability studies for such low-frequency rai…
A rotary frequency converter model for electromechanical transient studies of 16 Hz railway systems
John Laury, Lars Abrahamsson, Math H. J Bollen
Railway power systems operating at a nominal frequency below the frequency of the public grid (50 or 60 Hz) are special in many senses. One is that they exist in a just few countri…
Optimal Design of Hybrid AC/DC Microgrids
Hossein Lotfi, Amin Khodaei, Shay Bahramirad +1
DC loads (such as computers, data centres, electric vehicle chargers, and LED lamps) and dc distributed energy resources (such as fuel cells, solar photovoltaics, and energy storag…
Capturing the Variabilities of Distribution Network Net-Load via Available Flexibility of Microgrids
Alireza Majzoobi, Amin Khodaei, Shay Bahramirad +1
Renewable energy has attracted significant attention over the last decade, conceivably due to its environmental benefits and the recent drops in the development and deployment cost…
