Abstract

Wind energy is an intermittent renewable resource and the amount of electricity produced depends on wind conditions and turbine characteristics. Wind power capacity in the U.S. has reached more than 65 GW in 2014, which is up from 61 GW in 2013. The average power consumption for the state of Georgia for a month is 1098 kWh. Wind energy generation has attracted much interest in the last few years. Doubly-Fed Induction Generators (DFIGs) have some advantages over synchronous and induction generators when used in wind farms, such as variable speed operation, active and reactive power control, and lower converter cost. So this research proposal seeks to model and make a complete analysis for components of a wind turbine generator (WTG) system to store energy in the system and supply loads with the stored energy. Focus is placed on the storage of energy into a lead acid battery and using the battery with the inverter as a dispatchable energy source. As storage device and inverter acts as a steam power plant generator. Simulink is used to implement this system on three stages for all system’ elements like wind turbine, wind generator, loads, dc-dc converter, ac-dc inverter, controller and battery. Results show the validity of the work. We use the desired power value delivered to each load to determine characteristics of the wind turbine system. Some characteristics are: wind speed (m/s), rotor speed (RPM), torque (N.m), wind power (kW), and charging/discharging characteristics for the battery. We will design a wind turbine generator power system based off of the desired load and it’s characteristics with the aid of Simulink and power system toolbox in MATLAB. The battery storage system is optimized for maximum power output by minimizing losses at charge and discharge. Finally, the proposed real system to implement this simulation work is presented with its components in details on small scale. Such models may be tested together with other distributed system models in order to evaluate and predict the overall system performance. The proposed research presents an optimum operation wind power system micro-grid distribution generation for smart grid applications. The experimental test-bed is implemented to validate the simulation work even with small scale values. Availability of models of all these components at all stages in system development is very important in system sizing, cost analysis and monitoring.
