Abstract：A new control strategy is proposed based on the characteristics of hybrid excitation Synchronous Generator(HESG) and wind power generation systems, which can achieve maximum power point tracking(MPPT) and flexible control for the active power and the reactive power of the system. The speed of HESG is regulated by controlling the excitation current, which can make the speed of HESG operate in the optimal speed and will achieve maximum power point tracking. The three-phase grid-connected inverter of wind power generation systems is controlled by using the flexible power control in two-phase stationary reference frame, which can achieve decoupling and flexible control for the active power and the reactive power. Simulated and experimental results show that the system has a good steady and dynamic performance, and realizes maximum power point tracking.
