Traditionally, control strategies like Power System Stabilizers (PSS) in synchronous machines have proved to be effective in damping such oscillations in power systems dominated by synchronous generation , .
In and , it is pointed out that when parameters such as virtual impedance, virtual damping, and virtual inertia have specific proportional relationships, the active power oscillation during the parallel operation of VSG can be suppressed.
CONCLUSION This paper has investigated the damping capability of P-f/Q-V droop-based Grid-Forming power converters (GFOR) and it proposed supplementary power oscillation damping controllers for the active- and reactive-power injections (POD-P and POD-Q, respectively) to damp electromechanical oscillations.
Although virtual synchronous generators (VSGs) operating in parallel can provide inertial and damping support for isolated microgrids, when load disturbances occur, it will lead to problems such as active power and frequency oscillations.
