Abstract：In the distributed-generation grid-connected system, the grid-connected inverter and the filter are important to convert and transmit the energy. In this paper, a T filter which replaces the transitional L filter is used to reduce the harmonics of the grid-current. In order to avoid the instability of system to which the T-filter brings, this paper proposes an interconnection and damping assignment-passivity based control method which is based on the passivity based control, and analyses the stability of the controller in detail. The correctness and validity of the proposed control algorithm are proved to achieve stability with good stability and dynamic ability by simulation and experimental results.
