IEC 61850 enhances interoperability in smart grid communication compared to legacy protocols primarily through its standardized data models and communication services. Interoperability means that devices from different manufacturers can communicate and exchange information seamlessly. Legacy protocols, such as DNP3 and Modbus, often use proprietary data formats and communication methods, which make it difficult to integrate devices from different vendors. IEC 61850 defines a common language for smart grid devices, enabling them to understand each other regard....
