In recent years, High Voltage Direct Current (HVDC) and Medium Voltage Direct Current (MVDC) networks are being increasingly deployed in long distance power transmission and distribution, primarily because of its low power delivery loss, low construction cost, and easy control of power flow. Along with the development of HVDC/MVDC is the demand for more reliable HVDC/MVDC networks; thus, comprehensive and objective reliability evaluation for HVDC/MVDC networks has become a pressing topic. Previous research has been conducted for different types of HVDC/MVDC systems; however, real-time or operational reliability evaluation of HVDC/MVDC systems has not been studied thus far. For example, since HVDC transmission systems are being deployed to interconnect wind farms with the main grid, the volatile output of wind farms is able to affect the availability of power electronic devices on a real-time basis, and the reliability of the overall HVDC transmission system can be affected accordingly. This project aims at evaluating the operational reliability of HVDC/MVDC networks considering the real-time impact of power electronics. A comprehensive set of scenarios will be studied to demonstrate the real-time operational reliability of the HVDC/MVDC systems as well as the impact of the power electronics. In addition, a commercial-grade, comprehensive software tool will be developed for enabling informed decision-making in HVDC/MVDC-related power system planning and operations for a broad range of users.
