| Summary: | This research article presents a proposal and analysis of a multi-port converter designed to enhance electrical resilience for residential users located at the edge of the public service grid. The converter, which is capable of generating alternating current, is designed to decouple undesired effects at the common connection point with the electrical grid, particularly those commonly encountered in weak nodes. This objective is achieved through a decoupling stage that absorbs undesired dynamics by regulating a direct current link. Furthermore, by incorporating a self-generation and storage port, the system adds electrical energy management capability that allows the provision of auxiliary functions to the electrical grid and the maintenance of electrical supply during extended periods of grid unavailability. The validity of this proposal is supported by a reliability analysis based on Markov chains, and is experimentally validated through a prototype. The prototype is subjected to significant fluctuations in load to incorporate the worst-case scenario, as depicted by the CBEMA performance characteristic curve. The results demonstrate the ability of the converter to maintain a stable output voltage, improving the MTBF and ensuring continuous operation during grid disconnection. |
