摘要:
基于多智能体一致性理论，设计了具有完全分布式特征的微网能量管理调度策略，以解决集中式控制方式通信压力大和无法满足即插即用要求的问题。以可控发电单元和储能单元运行成本最低为目标函数，结合微网功率平衡和发电单元出力的约束条件，建立了分布控制式微网最优经济调度模型。根据多智能体及一致性理论设计了微网的分布式能量管理调度算法，给出了该方法的具体实施步骤。通过在IEEE-14节点微电网系统中的仿真算例，验证了所提出调度策略的正确性和有效性。

Abstract:
On the basis of the MAS consensus theory, this paper studies the distributed energy management scheduling strategy of the microgrid, aiming at solving the disadvantages of the central-controlled strategies such as high communication pressure and incapable of satisfying the requirement of plug and play. Taking the minimum cost of all controllable generators and the energy storage units as the objective function and combining the constraints of the microgrid power balance and generator outputs, the distributed-control optimal economic scheduling model of microgrids is established. According to the multi-agent system framework and consensus algorithm, this paper presents a distributed energy management algorithm for microgrids, and gives the concrete implementation steps of distributed energy management scheduling strategy of microgrids. Through the simulation of the IEEE-14 test system, the correctness and validity of the proposed scheduling strategy is verified.
