摘　　要：针对自治微电网不同状况下的功率供需平衡问题,提出基于多代理系统(MAS)的微电网有功协调控制方法。构建由分布式电源代理、负荷代理和上层代理组成的多代理控制系统,并对各代理具体功能进行详细分析。在可再生能源发电不足时,建立微电网的经济调度模型,通过调用CPLEX分支定界方法进行求解。在可再生能源发电充足时,建立计及发电利用率的微电网供需平衡模型,利用改进的次梯度算法求解模型中的凸优化问题。通过算例系统仿真,验证所述控制策略的有效性。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.
