Interface Protection and Energy Management System for Microgrid using Internet of Things

The restructuring of power systems, performance enhancements in the renewable energy generation technologies and evolutions in power electronics based high power switching devices has collectively facilitated the technical realization of microgrids in power systems. Reduction in Peak power demands on the main grid, good voltage regulation and utilization of renewable energy sources are the important technical benefits of Micro Grids with Distributed Energy Resources(DERs). Control and protection of micro grids during its various operating modes are very essential for the secure and reliable operation of microgrid interfaced main grids. Isolation of micro grids after a fault in main grid and energy management during mode transition are the important challenges of micro grids. The power electronics based micro grids requires faster isolation of faulty parts hence the operating time of the control and protection systems need to be faster. Hence this paper proposes a method for interface protection and energy management using Internet of Things (IoT).
