Modelling and Control Design for Variable Speed Wind Turbine Energy System

Renewable energy from wind is the safest form of energy. Wind turbine based energy generators have the potential to generate high amount of electric power if there is a proper wind velocity and control mechanisms. This can certainly reduce the dependency on solar photovoltaic based energy systems, which needs huge space to install the solar photovoltaic panels. However, the output power of wind turbine is affected by the uncertain wind velocity. The output mechanical power has to be properly controlled. Hence, the wind energy system efficacy depends on how well this uncertainty is addressed. The major challenge is to design and control the wind turbine systems that has a suitable mediator between the power generator and the load, which counters the damage to the load due to variable voltages produced by the varying wind velocity. Keeping this in view, this paper implements all-important PID control design methods for wind energy application and recommends the most suitable method for its controller design. The overall analysis is presented via detailed quantitative results that are evaluated with the help of time-domain performance index parameters.
