Matlab/Stateflow based-Multiagent System Application for Energy Management of Microgrid with Stand-alone Operation

Considering the environmental concerns, limitation of natural resources and power demand pressure, there is a great need to involve the distributed energy resource (DER) which can be operated as interconnected or as stand-alone mode from the main power grid. This paper proposes an application of Matlab/Stateflow-based MAS for energy management and control in a hybrid energy system including diesel generation system. An overall power management strategy is designed for the proposed system to manage power flows among different energy sources and the storage unit in the system. A simulation model for the hybrid energy system was developed using Matlab/Simulink and SimPowerSystems. The system performance under the different scenarios was verified by carrying out simulation studies using practical load demand profile and real weather data.
