Analysis of the Correlation Between Reliability Indices and Outage Costs in MVDC Systems

This study analyzes the correlation between reliability indices and outage costs in Medium Voltage Direct Current (MVDC) systems. By evaluating key reliability indices such as SAIDI, SAIFI, and EENS, the outage costs were calculated. The analysis results show a strong positive correlation between the reliability indices and outage costs, indicating that a decrease in reliability leads to increased economic losses. Based on these findings, we propose reliability improvement strategies for the efficient and stable operation of MVDC systems. This study provides fundamental data for enhancing the reliability of MVDC systems and contributes to improving the economic efficiency of power system operations.
