To solve the problem of the active power balance between supply and demand under different conditions, an active power coordination control method for autonomous microgrid based on the multi-agent system (MAS) is presented. It builds a MAS which consists of distributed generation agents, load agent, and upper agent. Their functions are described in detail. When the outputs of renewable generators are insufficient, the economic dispatch model of the autonomous microgrid is established, and the CPLEX branch-and-bound technique is adopted to solve the model. When the outputs of renewable generators are sufficient, the power supply and demand model of the autonomous microgrid is established, which includes the power utilizations, and the improved distributed subgradient algorithm is used to solve the convex optimization problem of the model. The effectiveness of the proposed control strategy is validated by the example system simulation.
