Abstract: Active distribution network（ADN） with high penetration of renewable energy will be faced with several operation problems, such as changeable topology, large scale of communication information, and large computing amount, etc. To cope with these problems, a distributed source-load-storage coordinative modeling method was proposed based on multi-agent system（MAS）. To improve limitations of centralized control mode of ADN, center-zone distributed control mode, center-unit distributed control mode and completely distributed control mode were introduced, and an analytical comparison of these three modes showed that the consensus based completely distributed one was the best solution considering topology and communication mode of ADN. Therefore, a source-grid-load MAS coordinative optimization model on the basis of consensus based completely distributed control mode was presented to maximize the profit of ADN. Meanwhile, the consensus terms were defined for further consensus based calculation.
