Web4 mar. 2013 · Control strategies are studied after modeling [15, 16] and VSC-based MTDC has attracted much attention [17, 18], especially for wind farm integration. At present, the common used VSC-MTDC control strategies are voltage drop characteristic method and master-slave method [20, 21]. But now all these strategies are still in the stage of … WebFurther, a back/forward iterative method for the AC/DC distribution system incorporating VSC-MTDC is proposed. At last, the effectiveness of the back/forward iterative method is verified with a modified IEEE14 bus AC/DC distribution system. The algorithm achieves bi-direction power flow calculation and converges to control objection of inverters.
