- <p>This master's thesis investigates the role of multiport power converters (MPCs) in enhancing the resilience and efficiency of distribution grids. The research focuses on reducing energy not supplied (ENS) and facilitating the integration of distributed energy resources (DER). Utilizing a modified IEEE 33-bus test system, simulations were conducted to evaluate the performance of MPCs under various scenarios, including single- and double-line failures and grid-forming and grid-following operation modes of distributed generation (DG) units.</p> <p>Despite that in the base case the electrical performance of the distribution grid is already acceptable, the study reveals that MPCs significantly improve grid performance, particularly in voltage regulation and loss reduction. Economic feasibility analysis indicates that partial-scale MPCs provide a more cost-effective solution for grid performance enhancement. Additionally, the research assesses the potential revenue from battery energy storage systems (BESS) participation in electricity markets, highlighting the revenues from day-ahead markets and ancillary services markets. The findings support the adoption of MPCs as a viable strategy for modernizing distribution networks to accommodate increasing DER integration and achieve sustainable energy objectives.</p>
