论文摘要
在本文中，我们提出了DC Mcirogroids的原始分布式控制框架。我们首先将（最佳）控制目标制定为适合能源交易市场的总体游戏。然后，基于双重理论，我们分析了所提出的聚合游戏的等效分布式最佳条件，并设计了一个分布式控制方案来解决它。通过以保持功率保留方式将直流麦伦格里德和设计的分布式控制系统互连，我们将直流微电网的状态引导到所需的最佳平衡，满足一组预定义的局部和耦合约束。最后，基于奇异的扰动系统理论，我们分析了闭环系统的收敛性。仿真结果显示了所提出的控制框架的出色表现。
In this paper we propose an original distributed control framework for DC mcirogrids. We first formulate the (optimal) control objectives as an aggregative game suitable for the energy trading market. Then, based on the dual theory, we analyze the equivalent distributed optimal condition for the proposed aggregative game and design a distributed control scheme to solve it. By interconnecting the DC mcirogrid and the designed distributed control system in a power preserving way, we steer the DC microgrid's state to the desired optimal equilibrium, satisfying a predefined set of local and coupling constraints. Finally, based on the singular perturbation system theory, we analyze the convergence of the closed-loop system. The simulation results show excellent performance of the proposed control framework.
