A Direct Current (DC) bus architecture is essential today as a large portion of modern appliances operate on DC power. However, a traditional Power Control Unit (PCU) typically does not support DC load integration. This paper proposes an advanced PCU facilitating a DC bus arrangement designed to integrate Distributed Energy Resources (DERs) into a conventional single-phase grid, enabling efficient power supply to residential buildings. The system facilitates seamless interfacing of DERs, DC/AC loads, and a battery energy storage system under a unified, coordinated control scheme. The proposed PCU ensures efficient power management, maintains stable DC bus voltage, and automatically adapts to common challenges such as islanding conditions and fluctuations in input power from variable renewable sources like solar and wind. Simulation results validate the effectiveness of the system in both grid-connected and islanded operating modes, demonstrating its capability to maintain system stability and reliability.
Key words: Power control unit / Distributed energy resources / Battery energy storage system / Hysteresis current controller / Sliding mode controller
