ABSTRACT
The increasing variety of DC microgrid configurations has created a challenge for engineers in selecting the optimal design. To address this, Multi-Criteria Decision Analysis (MCDA) provides a systematic approach. In this study, five distinct DC microgrid configurations are defined as potential alternatives: unipolar, bipolar, multi-terminal topology, multi-bus topology, ring topology, and AC microgrid. MCDA allows for the establishment of relevant evaluation criteria specific to each configuration, such as pro-tection schemes, fault resilience, and overall system cost. By systematically analysing the MCDA results using the AHP tech-nique, the most suitable DC microgrid design can be identified, which inherently determines the optimal type of distribution bus. AHP assigns weights to each evaluation criterion based on its relative importance. The study concludes with a comprehensive sensitivity analysis and an investigation of optimization techniques. This assessment integrates perspectives from both expert judgments and relevant scientific publications.
