An optimized control scheme for a single-phase grid-forming photovoltaic-supercapacitor system considering dynamic response improvement and double-line frequency power decoupling is proposed. Compared with the conventional scheme, this scheme integrates the supercapacitor energy storage with double-line frequency power decoupling, and there is no need for additional power decoupling circuits. The DC-link proportional integral resonant control, virtual rotor kinetic energy feedforward control and photovoltaic power feedforward control suitable for this topology are studied, so that the capacitance of the DC-link capacitor and supercapacitor is reduced. In addition, a small-signal linearized model for the second-order generalized integrator-based power calculation part is established, and a sector-based state feedback damping control scheme is put forward to improve the dynamic performance of the system. Experimental results verified the effectiveness of the proposed control scheme.
