  • Short-Term Reliability Assessment of UHVdc Systems Based

    Jun 17, 2019Abstract: The short-term reliability of the ultra-high-voltage dc (UHVdc) systems has enormous influence on the security of the whole power system. The frequency and duration (FD) algorithm based on the Markov process (MP) will reduce the accuracy of the short-term reliability indices, due to the exponentially distributed parameters and the strict premises for the state aggregation andCited by: 2
