17 An Efficient Approach to Power Coefficient and Tip Speed Ratio Relationship Modeling in Maximum Power Point Tracking of Wind Power Generation

As a developing country, Bangladesh has a rapidly increasing demand of electric power for the development of its socio-economic condition. In the context of Bangladesh, one of the solutions for renewable energy sources is wind energy, especially in coastal areas. For maximum utilization of wind energy, MPPT (Maximum Power Point Tracking) is preferred in implementation of wind farms. Maximum power point tracking increases total power output, thus making the system more cost efficient. MPPT involves estimation of future wind data, working out logical relation between Tip Speed Ratio (λ) and Power Coefficient (C_p). This relation is found to vital as wind farms operate in very agile, dynamic and robust condition. Thus, this paper aims at finding a logical relation between C_p and λ and showing its usage for realizing MPPT. A unique relation between C_p and λ is proposed in this paper in order to investigate power generation without MPPT. A comparison is made with real data to show the effectiveness our approach to find non-optimal generated power as well to.
