Operation and Supervision Control in Smart Transformer-based Meshed and Hybrid Grids

Solid-state transformer-based smart transformer (ST) can operate in meshed and hybrid grids, which can increase the hosting capacity of renewables and meanwhile reduce the reinforcements in electric grids. In order to adapt the new paradigm, the system performances of the ST-based meshed and hybrid grids are studied and then an effective energy management system (EMS), which is based on a distributed control architecture, is presented to control the meshed and hybrid grids operating in an intelligent and coordinated way.
