    Design a Grid Tie Inverter for PMSG Wind Turbine using FPGA & DSP Builder
    (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2016) Çolak, İlhami; Hossain, Eklas; Bayındır, Ramazan; Hossain, Jakir
    The recent makeshift in fuel choice, renewable energy sources has been considered as the most popular form of its kind because of its environment friendly approaches, less cost tariff policy and the natural fuel abundance. This inclusion in power system promotes Micro-grid system to optimize the overall distribution. FPGA, elaborated as Field Programmable Gate Array, proposes chances for enhanced performance and coveted flexibility in design for the digital control. Conversely, the erudite convolution of the Hardware Description Language (HDL) coding, a way translating to HDL, can be an undesirable hurdle for the professional system designers. The design, depicted in this letter, is an instance of system modeling for FPGA-based digital control, which necessarily has the desired ability to auto-generate the HDL codes. The architecture of this design uses the DSP Builder technology, in a MATLAB / SIMULINK platform. A three phase full-bridge gird tied inverter for wind system and a three phase full-bridge inverter for grid connected wind system are built that demonstrates the close correlation with the model. The necessary simulations, results and the experimental analysis have also been highlighted for the different control techniques such as PI, dq, and the PWM control technique.

    Designing a Competitive Electric Vehicle Charging Station with Solar PV and Storage
    (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015) Çolak, İlhami; Bayındır, Ramazan; Aksöz, Ahmet; Hossain, Eklas; Sayılgan, Sabri
    An electrical vehicle charging station is a charging power supply for electrical vehicles. This paper proposes design of a model for a PV based electrical vehicle that forecasts total power output under particular conditions of Ankara city. First PV cell parameters are determined and then PV array formed including cells designed in order to calculate cumulative effect. Using actual irradiation and temperature values we try to catch an approximation of output power for the future needs.

    Voltage and Frequency Stability Analysis of AC Microgrid
    (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015) Çolak, İlhami; Bayındır, Ramazan; Al-Nussari, Mohammed; Hossain, Eklas
    Microgrid is a single controllable unit constituting distributed generation (DG) and load in the power system. The micro source includes photovoltaic (PV) cells, wind turbine, micro turbine, fuel cell, electric accumulator and flywheel etc. Usually, the micro source operates in parallel with the normal distributed network that uses the power electronic devices. There are two typical operation modes of micro grid as the grid-connected mode and islanding mode. Thus, the running control problem is one key issue of the microgrid, which needs to be resolved in the actual operation. For exact synchronism, to protect the system and to reduce the load in case of imbalance condition, a control system is necessary to bring the system instability while providing efficient and robust electricity to the micro grid. This paper mainly analyses the micro sources with different types of loads and dispersion characteristics in different operating mode using droop control method.
