| Outline of Final Research Achievements |
This study developed three methods for grid-connected power conversion systems; filter-resonance damping control, fast and wide system stabilization, and efficient simulation methods. An active damping control based on virtual resistors is developed to suppress filter resonances. An energy-based control method based on the Lyapunov function is developed to stabilize the system fast and widely. A new stabilized control method which can suppress the resonance is developed with combination of the above two control methods, and it is validated theoretically and experimentally. A fast and efficient simulation method based on the circuit-partitioning technique is developed and modified for applications including digital control programs. The three developed methods are useful to develop stable grid systems without filter resonances.
