Abstract Reliability optimal distribution (ROD) for high voltage direct current (HVDC) transmission systems can be used to choose reliability parameters of components to meet the requirement of a pre-specified system reliability performance. It is becoming an important means of decision-making for HVDC transmission project of bidding, planning and designing processes. Based on the property of the system reliability increasing with the reliability performance of components, this paper proposes a non-linear programming model for the ROD, which considers a wide range of constraints including the pre-specified system reliability. This model can be solved using the bisection method. Therefore, the optimal reliability parameters of components can be obtained. Case study of a HVDC transmission system of single 12-pulse was used to illustrate the performance of the proposed algorithm. A wide range of system reliability indices including the forced energy unavailability (FEA) and monopole forced outage times (MUOT) are the pre-specified indices. Results from the case study show that the method is feasible and effective.
