In a large-scale microgrid, the choice between a centralized and decentralized energy management system (EMS) involves several trade-offs related to communication infrastructure, computational complexity, resilience, scalability, and cost. A centralized EMS collects data from all devices in the microgrid and performs optimization and control functions at a central location. This approach allows for a global view of the system and enables sophisticated optimization algorithms to be implemented, potentially leading to more efficient operation. However, it requires a robust and high-bandwidth communication infrastructure to transmit data from all devices to the central controller. The computational complexity of the optimization algorithms can also be high, especially for large-scale microgrids with many distri....
