Reliability Evaluation Method of AC/DC Hybrid Distribution Network Considering Voltage Source Converter Restoration Capability and Network Reconfiguration

In the AC/DC hybrid distribution network, non-faulty areas can maintain uninterrupted power supply by adjusting control mode of voltage source converter (VSC) after a fault. addition, also be restored through network reconfiguration. To account for impact these two restoration methods on reliability accurately, this article proposed evaluation method considering VSC capability and First, optimization model reconfiguration modes is established, which give full play to while ensuring radial constraints network. Then, failure effects analysis (FMEA) introduced combined with analyze caused faults Among them, FMEA utilized determine topology fault isolation, basis, solved obtain outage time loads in Finally, aforementioned work sequential Monte Carlo evaluate adequately simulate fluctuation characteristics distributed generation (DG) load. The case study shows that accurately
