摘要

In this chapter, the basic structure for the distributed secondary control is established, where the control protocol is made up of pinning-based and consensus-based algorithms. On this basis, the saddle-node bifurcation behavior, subcritical Hopf bifurcation behavior, and hidden attractors of the microgrid are studied. It is also found that the location of pinned controllers and the topology of communication network have a significant impact on the microgrid stability. Finally, a design procedure of the distributed secondary control system is demonstrated.
