Item On-board Vehicle-to-Grid (V2G) integrator for power transaction in smart grid environment(Institute of Electrical and Electronics Engineers Inc., 2014) Koduri, N.; Hampannavar, S.; Yaragatti, R.Y.The growing oil demands and the economic concerns have inspired the governments, car manufactures and the environmentalist to promote the manufacturing of Electrical Vehicles (EV). With developments in the power grid and advancements in the vehicle technology the EVs can contribute to the grid by selling or buying power from the grid. For the effective and efficient use of the V2G there is a major scope to develop the V2G integrators like On-Board and Off-Board. In this paper the On-Board V2G integrator is proposed and is modeled using MATLAB/SIMULINK. The conversion efficiency of 90% is obtained and the benefits of V2G are listed. © 2014 IEEE.Item Modeling and architectural frame work of off-board V2G integrator for smart grid(International Journal of Renewable Energy Research icolak@gazi.edu.tr, 2014) Hampannavar, S.; Yaragatti, R.Y.; Swapna, M.The serious environmental concerns and growing oil demands have influenced the development of Electrical Vehicles (EV). The group of EVs can contribute largely to the grid requirements and participate in power transaction in order to meet the load demands. The Vehicle-to-Grid (V2G) helps in maintaining the power system stability for a short duration of time. The Off-Board and On-Board are two types integrators used for connecting EVs to the electric grid. In this paper the Off-Board V2G integrator framework is proposed. The modeling and simulation is carried out using MATLAB/SIMULINK. The V2G (discharging) operation is considered with two EVs connected to the grid.Item Development of wireless access support for EV to smart meter communication in vehicle-to-grid (V2G)(International Journal of Renewable Energy Research icolak@gazi.edu.tr, 2015) Hampannavar, S.; Yaragatti, R.Y.Vehicle -to-Grid (V2G) supports ancillary services like peak shaving, valley filling, load levelling and the battery of the electric vehicle (EV) provide reactive power support to the grid. V2G also helps in maintaining the grid stability forshort duration of time. The communication between EV and the Smart Meter is very crucial for smooth functioning of V2G. The WiFi single input single ouput/multiple input multiple output(SISO/MIMO) protocol is proposed for EV to Smart Meter communication in indoor wireless environment. The channel models B and C are used as they are developed for residential apartment and office buildingsdue to the fact that EVs are usually parked in these locations. The MIMO environment is considered for simulating these channel models. The physical layer of WiFi (SISO) protocol is modeled in MATLAB/SIMULINK and its performance is investigated.Item Modeling and comprehensive analysis of WiMAX protocol for grid control center to aggregator communication in vehicle-to-grid (V2G)(International Journal of Renewable Energy Research icolak@gazi.edu.tr, 2015) Hampannavar, S.; Yaragatti, R.Y.V2G has become a reality with development in power grid and advancements in vehicle technology. The electric vehicles (EV) will gradually replace the existing vehicles due to growing oil demand and environment concerns. The EVs can be integrated to the grid for power transaction and can contribute power to the grid. The Grid Control Center (GCC) to aggregator communication is very crucial in V2G operation in order to meet the load demand. The fixed WiMAX (Worldwide Interoperability for Microwave Access) protocol is proposed for GCC to aggregator communication. The applicable path loss models for WiMAX protocol are analysed and compared. The physical layer of WiMAX protocol is modeled in MATLAB/SIMULINK and its performance is investigated.Item Development of Wireless Access Support for EV to Smart Meter Communication in Vehicle-to-Grid (V2G)(Gazi Universitesi, 2015) Hampannavar, S.; R.y, U.Vehicle -to-Grid (V2G) supports ancillary services like peak shaving, valley filling, load levelling and the battery of the electric vehicle (EV) provide reactive power support to the grid.
