Adaptive MPPT control algorithm for small-scale wind energy conversion systems

This paper presents a new adaptive control scheme for small-scale wind energy conversion systems to extract maximum power from turbulent wind for microgrid systems. To improve the system reliability, the proposed maximum power point tracking algorithm is implemented without using mechanical sensors for the measurement of wind speed and generator speed. These two mechanical quantities are estimated from the measured electrical quantities of the system. During initial stage of execution, the control algorithm runs in system-independent mode and after acquiring system related information, it enters into system-specific mode. Effectiveness of the proposed control scheme is verified through simulation studies.
