“…On modern wind turbines, it is possible to adjust the angle of the blades through a control mechanism [11]. If C p -curve is known for a specific wind with a radius of turbine rotor R turbine , it is easy to construct the curve of C p as a function of rotational speed for a wind speed v wind .…”

In this paper, the control scheme of a wind energy conversion system for remote sites using fuzzy logic is presented. Two fuzzy controllers are proposed: the first one is dedicated to the maximum power point tracking (MPPT) of a variable speed permanent magnet synchronous generator wind turbine. The second fuzzy controller has the the objective to manage both the production and the storage of electricity for optimum performances of the system in respecting load demand. Several simulation results are given to show the effectiveness and the good performances of the proposed control structure.

“…The highest value of C p is typically obtained for λ values in the range of 8 to 9 (when the tip of the blades moves 8 to 9 times faster than incoming wind). On modern wind turbines, it is possible to adjust the pitch angle of the entire blade through servo mechanism (Jorgensen et al, 1997;Charly, 2007). Assuming constant wind speed V wind , the tips speed ratio λ will vary proportionally to the rotational speed of wind turbine rotor.If C p -λ curve is known for specific wind turbine with a turbine rotor radius R, it is easy to construct the curve of C p against rotational speed for any wind speed.…”

Abstract:In the growing electricity supply industry and open access market for electricity worldwide, renewable sources are getting added into the grid system. This affects the grid power quality. To assess the impact on grid due to wind energy integration, the knowledge of electrical characteristic of wind turbine and associated control equipments are required.The paper presents a simulation set-up for wind turbine in MATLAB / SIMULINK, with front end converter and interconnected system. The presented control scheme provides the wind power flow to the grid through a converter. The injected power in the system at the point of common coupling is ensured within the power quality norms.
