    Analysis of Output Voltage Harmonics of Voltage Source Inverter used PI and PID Controllers Optimized with ITAE Performance Criteria
    (E D P Sciences, 2017) Gul, Ozan; Tan, Nusret
    In this article, PI and PID controllers are designed using ITAE (Integral Time Absolute Error) Performance Criteria in order to obtain the controller parameters assuring Unproved response at selected load. The voltage source inverter (VSI) including PI and PID controllers whose parameters are estimated by minimizing errors using ITAE performance criteria are modeled in MATLAB environment. The stability analysis of the control system will be presented. VSI controlled with the PI-ITAE and the PID-ITAE controller are simulated for various loads and the results are analyzed using FFT analysis for observing and comparing the total harmonic distortion (THD) of the output voltage. The quality of the sinusoidal waveform is more important than the quantity and in order to achieve that, we need to reduce the harmonic content in the output.

    Effect of Shunt Capacitors on Power Systems Containing Renewable Energy Resources
    (Ieee, 2015) Gul, Ozan; Kaygusuz, Asim; Tan, Nusret
    In this paper, the effects of shunt capacitor on electrical network integrated with renewable energy resources are investigated. For this proposes, we conduct 24-hours load flow analyses for IEEE 39 buses power system containing intermittent renewable sources modeled by hourly generation profiles during a day using Matlab program, and then shunt capacitor connected to the selected load buses on systems and power factor changes in buses are evaluated during a day.

    A smart building power management concept: Smart socket applications with DC distribution
    (Elsevier Sci Ltd, 2015) Keles, Cemal; Karabiber, Abdulkerim; Akcin, Murat; Kaygusuz, Asim; Alagoz, Bads Baykant; Gul, Ozan
    Recent developments in power electronics increase DC bus utilization in electrical distribution systems due to its numerous advantages compared to AC distribution system in term of energy efficiency, safety, electromagnetic compatibility and renewable energy integration. This study presents a power management system concept based on domestic DC distribution with smart sockets for future smart houses. Energy efficient smart buildings are possible by integrating smart meter, smart sockets, domestic renewable energy generation and energy storage systems for integrated energy management, and this integrated system supports demand side load management, distributed generation and distributed storage provisions of future smart grids. Coming era of smart grids has implications for domestic DC distribution concepts with smarts sockets. Paper describes use of smart DC sockets as an integral part of building power management automation and presents a load shedding algorithm for plug load control for buildings. Simulations show performance of the proposed system components. (C) 2014 Elsevier Ltd. All rights reserved.
