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 ... -
Multi-Agent model of electricity networks - a perspective on distribution network charges
Pisica, Ioana; Ceylan, Oğuzhan (Institute of Electrical and Electronics Engineers Inc., 2019)In the UK, DNOs are regulated by Ofgem to use two common distribution use of system charging methodologies: Common Distribution Charging Methodology and Extra-High Voltage Distribution Charging Methodology. To account for ... -
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 ... -
Voltage Control of Unbalanced Distribution Systems with Penetration of Renewable Sources: A Gradient-Based Optimization Approach
Ebadi, Ramin; Senyuz, Hande; Aboshady, Fathy; Ceylan, Oguzhan; Pisica, Ioana; Ozdemir, Aydogan (IEEE, 2022)The penetration of distributed energy resources (DERs), including renewable energy sources (RES), into electric power systems has led to several challenges for the system operators. Despite various economic and environmental ...
