Research on OPF and Reliability Evaluation of VSC-MTDC System Considering Wind Power Connection

Based on the characteristics of clean energy integration in the Energy Internet, this paper proposes an optimal AC/DC power flow algorithm of multi-terminal flexible dc transmission system considering wind power connection. Combined with the analysis and research on the reliability evaluation system of comprehensive energy system, a simulation model of VSC-MTDC system is established to calculate the power flow distribution. By analyzing and comparing the calculation results before and after the OPF of the VSC-MTDC system, the effectiveness of the optimization method proposed in this paper is verified, which provides theoretical basis and data foundation for the further development of energy Internet.
