A Virtual Inertia Control Method for Series-type Inverters System in Islanded Mode

This paper proposes a virtual inertia power factor angle droop (VI-PFA-droop) control to improve dynamic frequency stability of series-type inverters in islanded mode. This control method can provide necessary inertia support while achieve excellent power balance under different loads. Eigenvalue analysis of is finished to prove the small signal stability. And the feasibility of the proposed method is verified by experiment results on Hardware-In-the-Loop.
