Analysis of Local and Centralized Control of PV Inverters for Voltage Support in Distribution Feeders
Ceylan, Oguzhan; Paudyal, Sumit; Pisica, Ioana (IEEE, 2021)Higher photovoltaic penetration on distribution system brings operational challenges including overvoltage issues. With smart inverters, efficient voltage control can be achieved through adjusting active/reactive powers ... -
Assessment of Harmonic Distortion on Distribution Feeders with Electric Vehicles and Residential PVs
Ceylan, Oğuzhan; Paudyal, Sumit; Dahal, Sudarshan; Karki, Nava R. (IEEE, 2017)Power-electronic interfacing based devices such as photovoltaic (PV) panels and electric vehicles (EVs) cause voltage/current harmonic distortions on the power grid. The harmonic current profiles from EVs and PVs depend ... -
Comparative Study of Active Power Curtailment Methods of PVs for Preventing Overvoltage on Distribution Feeders
Paudyal, Sumit; Bhattarai, Bishnu P.; Tonkoski, Reinaldo; Dahal, Sudarshan; Ceylan, Oğuzhan (IEEE, 2018)Overvoltage is one of the major issues on distribution grids with high penetration of photovoltaic (PV) generation. Overvoltage could be prevented through the control of active/reactive power of PVs. However given the high ... -

Ceylan, Oğuzhan; Taşkın, Gülsen; Paudyal, Sumit (IEEE, 2020)Due to increasing volume of measurements in smart grids, surrogate based learning approaches for modeling the power grids are becoming popular. This paper uses regression based models to find the unknown state variables ... -
Coordinated Electric Vehicle Charging With Reactive Power Support to Distribution Grids
Wang, Jingyuan; Bharati, Guna R.; Paudyal, Sumit; Ceylan, Oğuzhan; Bhattarai, Bishnu P.; Myers, Kurt S. (IEEE, 2019)We develop hierarchical coordination frameworks to optimally manage active and reactive power dispatch of number of spatially distributed electric vehicles (EVs) incorporating distribution grid level constraints. The ... -
Nodal Sensitivity-Based Smart Inverter Control for Voltage Regulation in Distribution Feeder
Ceylan, Oğuzhan; Paudyal, Sumit; Pisica, Ioana (IEEE Electron Devices Society, 2021)Overvoltage is one of the issues in distribution grids with high penetration of photovoltaics (PVs). Centralized or droop-based methods of active power curtailment (APC) and/or reactive power control of PVs are viable ... -
Semi-Centralized Control of Distributed Generation in Smart Grids
Ceylan, Oğuzhan; Pisica, Ioana; Paudyal, Sumit (IEEE, 2018)This paper proposes a semi-centralized intelligent control approach for voltage regulation in distribution grids based on sensitivity calculations. The model checks the voltage magnitudes of each end of each lateral in the ...
