| Abstract | ||
| The number of renewable and decentralized power plants is rising globally, due to the need to minimize emissions that have an impact on the climate. The hybrid distribution network has recently attracted much attention since it combines the best features of AC and DC microgrids (MGs). Despite the several benefits of integrating a hybrid MG into the distribution network, it also offers some challenges. The development of a reliable protection system generalized for both AC and DC sub-MGs and the coordination between them is one of the most important challenges facing hybrid MG technology. Even though they both have a substantial mutual influence, most recent studies only concentrate on one side, DC or AC. This study thoroughly analyzes the system under various conditions and discusses some recent protective strategies that can be applied to such a system. The study also outlines the benefits of the hybrid AC/DC network and some of the protection challenges that the hybrid MG faces. The research also compares the system behavior under both disturbance and fault conditions. Additionally, a thorough illustration is provided of how a fault in the AC-microgrid (MG) affects the DC-MG and vice versa. | ||
