Control of Virtual Synchronous Generator Combined With Active Power Smoothing
A novel control strategy for virtual synchronous generator combined with active power smoothing is proposed. This strategy not only enables grid-connected inverters to obtain moments of inertia,and the ability of participating in micro-grid frequency adjustment and voltage regulator, just like the synchronous generator, but also enables the inverters to smooth active power fluctuation of micro-grid. Virtual synchronous generator current generation algorithm, active power smoothing current generation algorithm, and the integration of the two algorithms is proposed. Meanwhile, the tracking control method of instruction current based on repetitive and PI control is given. System simulation is carried out on MATLAB / Simulink and simulation results verify the validity of the proposed control strategy.
