A Battery-Oriented Multiport DC-DC Converter for Enhanced Power Management in SST

Year: 2025

Type: conference-paper

Abstract: In response to the growing demand for technological solutions aimed at enhancing the stability of electrical power systems, this paper proposes a new approach to power flow management in solid-state transformers (SST). Within the context of smart grids, the increasing integration of renewable energy sources (RES) introduces greater uncertainty and variability, making it critical to balance mismatched generation and consumption periods. This study explores the integration of batteries into the core of the SST architecture, targeting power grid stabilization and galvanic isolation between the medium-voltage (MV) and low-voltage (LV) subsystems. To this end, a triple active bridge (TAB) converter is used in the SST’s isolated stage, offering enhanced flexibility and resilience by enabling energy storage and demand-driven power routing. Computational simulations validate the proposed multiport DC-DC converter, which employs a dual-phase shift (DPS) modulation to control both the direction and magnitude of the power flow. The results confirm the approach’s compatibility with modern electrical power systems, addressing the main challenges and opportunities.
