Microgrid technology provides a solution which improves grid reliability and reduces environmental pollution through coordinated dispatching distributed generation energy storage device and loads.But because of its flexible structure and support of various types of distributed generations and loads,microgrid is more complex to be controlled than traditional grid.Now microgrid control technology is the important subject on microgrid research field.There are two questions that need to be solved in the field of microgrid control,one is loads can receive high quality electirc power when the system is in process of grid connection,grid isolation and grid connection/ isolation conversion,the other is microgrid control systems can coordinate scheduling the microgrid components,guarantee the stability of the system when the system fault.Multi-agent system is a new artificial intelligence technology,its flexibility and distributed features meet the demand for coordination and control of the microgrid distributed generation.It is important to research on MAS on microgrid research field.The thesis first analyzes the microgrid network structure,and selects hybrid AC/DC microgrid structure as the object of study.Second,through the analyzes of FIPA standard,the thesis selects JADE as a MAS development platform.The function of microgrid agents has been designed,which include MGC Agent,PV Agent,Battery Agent and Load Agent.Third the photovoltaic unit,battery and inverter controller simulation model has been designed in the Matlab/Simulink environment and the thesis analyzes the characteristics curve of the photovoltaic cell and MPPT.Lastly the thesis selects hybrid AC-DC microgrid as the control object of the MAS.Coordination layer of MGC Agent and execution layer of microgrid equipment agent has been builded in the MAS,the hybrid AC/DC microgrid system has achieved coordinated control.
