 Micro-grid is an advanced application to utilize distributed renewable energy． Due to the randomness and intermittency of renewable energy and the environmental uncertainty，it is important to seek an effective dynamic reconfiguration strategy to ensure the efficient and stable operation of micro-grid． To solve the problem of micro-grid energy management，a dynamic reconfiguration strategy was proposed for micro-grid architecture based on the multi-agent system ( MAS) technology． Firstly，the mathematic model of micro-grid aiming at a maximum economic benefit is built based on the analysis of the excitation conditions and basic characteristics of micro-grid's reconfiguration． Secondly，the micro-grid energy management system ( MEMS) based on MAS and the potential game algorithm introduced as the core optimization algorithm is built based on the self-benefit maximization of distributed power supply． It realized the dynamic reconfiguration of micro-grid through the interaction of each agent． Potential game has excellent distributed characteristics that realize absolute distributed dynamic reconfiguration by combining topology with core optimization algorithm． Finally，simulation verification was carried out by an example of islanded micro-grid． Simulation results show that micro-grid can realize effectivelly dynamic reconfiguration while ensuring that individuals have sufficient autonomy and independent decision-making ability． Simulation results also verify the validity of the proposed methods．
