要約(日本語): In order for large-scale wind power transmissions, a multi-terminal VSC HVDC system installation is considered in this paper. Optimal power flow analysis with system constraint considerations is carried out. DC grid transient stability is also taken into account in the analysis. As the DC fault type, bipole-to-ground faults are considered to simulate the most severe condition. A protection strategy to prevent the fault propagations in both AC and DC grids is explained. The numerical results are discussed to be effective to find the optimal operation solution while maintaining DC grid transient stability.
