At present, the hierarchical control strategy which includes cyber and physical layers is one of the most widely used control strategies in networked direct current microgrid. In general, through the controller and actuator, the communication data in cyber layer can be used to accomplish the control missions in physical layer, e.g. achieving stable operation or economic operation etc. However, when actuator fault occurs in communication, the normal operation of cyber layer will be affected. Thus, the control effect of physical layer will be also affected. Considering with the above problems, a hierarchical control strategy based on adaptive dynamic program and event-triggered consensus algorithms is proposed to realize the economic operation of microgrid. In this strategy, the main designs are as follows: 1. To deal with the actuator fault problem in the process of consensus control, the fault observer and adaptive dynamic program-based controller are designed in the cyber layer; 2. Also in the cyber layer, an event-triggered consensus algorithm is proposed to adjust distributed energy resources to output their optimal power and make microgrid run economically; 3. To maintain the voltage stable while the power is adjusted, a secondary control strategy is proposed in the physical layer. Finally, the experimental results have verified the effectiveness of the designed strategies.

目前，包括网络层和物理层的分层控制策略是网络化直流微电网中使用最广泛的控制策略之一。通常，通过控制器和执行器，网络层的通信数据可用于完成物理层的控制任务，例如实现稳定运行或经济运行等。但是，当执行器在通信中发生故障时，网络的正常运行层将受到影响。因此，物理层的控制效果也会受到影响。针对上述问题，提出了一种基于自适应动态程序和事件触发共识算法的分层控制策略，以实现微电网的经济运行。在此策略中，主要设计如下：1。为了解决共识控制过程中的执行器故障问题，在网络层设计了故障观测器和自适应动态程序控制器。2.同样在网络层，提出了一种事件触发的共识算法，以调整分布式能源以输出其最佳功率，并使微电网经济运行；3.为了在调整电源时保持电压稳定，在物理层中提出了一种辅助控制策略。最后，实验结果验证了所设计策略的有效性。提出了一种事件触发的共识算法，用于调整分布式能源以输出其最优功率，并使微电网经济运行。3.为了在调整电源时保持电压稳定，在物理层中提出了一种辅助控制策略。最后，实验结果验证了所设计策略的有效性。提出了一种事件触发的共识算法，用于调整分布式能源以输出其最优功率，并使微电网经济运行。3.为了在调整电源时保持电压稳定，在物理层中提出了一种辅助控制策略。最后，实验结果验证了所设计策略的有效性。
