报告简介:Initially, for the three-phase grid-connected inverters, inverter current limitation is achieved by embedding droop control dynamics into both nonlinear bounded integral controller (BIC) and state- limiting PI (sl-PI) controllers, the closed-loop system stability is examined, and the analytic stability conditions are provided. Furthermore, an improved virtual synchronous control structure is proposed by coupling DC-link voltage and AC frequency dynamics and applied to three-phase grid-connected inverters. Finally, a nonlinear droop controller that can guarantee the current-limiting property and avoid the undesired circulating current issue in AC microgrids with parallel three-phase inverters is designed. The performances of proposed controllers are verified via simulation, experimental and hardware-in-the loop studies considering both grid-connected and stand- alone modes.
