Virtual synchronous generator (VSG) has been developed recent years as a promising grid-tied inverter control strategy because it can improve the penetration of the renewable energy. Due to introducing virtual inertia, the active power loop of VSG behaves as a typical second-order system, which may cause active power oscillation. It is a key issue that designing the parameters of active power control...
This paper proposes a robust tracking method with application to the DC-AC PWM converter of the green energy. The proposed method has the merits of hyperbolic tangential sliding hyperplane (HTSH), grey prediction (GP) and firefly algorithm (FA). The HTSH has the robustness of classical sliding mode control (SMC) and increases the system's convergence speed. However, once a highly nonlinear load occurs,...
