Analytical approach for adequacy assessment of cyber–physical multi-microgrid distribution systems with distributed generation
Barani, Mostafa; Vadlamudi, Vijay Venu (Peer reviewed; Journal article, 2022)In recent years, there has been a marked increase in the deployment of information and communication technologies (ICTs) in power systems. ICTs impart a cyber-physical nature to power systems, and though they improve the ... -
BATTPOWER Toolbox: Memory-Efficient and High-Performance Multi-Period AC Optimal Power Flow Solver
Zaferanlouei, Salman; Farahmand, Hossein; Vadlamudi, Vijay Venu; Korpås, Magnus (Peer reviewed; Journal article, 2021)In this paper, we introduce an Interior Point-based (IP) Multi-Period AC Optimal Power Flow (MPOPF) solver for the integration of Stationary Energy Storage Systems (SESS) and Electric Vehicles (EV). The primary methodology ... -
The Effect of Non-Ideal Operating Conditions on Reliability of Inverters in Microgrids
Berg, Sondre Johan Kjellin; Göthner, Fredrik T. B. W.; Vadlamudi, Vijay Venu; Peftitsis, Dimosthenis (Peer reviewed; Journal article, 2020)Microgrids are becoming increasingly popular due to modern trends in power consumption and distribution.
