ADMM-based consensus droop control and distributed pinning droop control of isolated AC microgrids

In this chapter, we will focus on the primary and secondary controls for proper power sharing and set-point restoring operations of MGs. Traditionally, the power sharing is achieved by the decentralized droop scheme of each DIC. Although proper real power sharing can be achieved in most existing methods, incorrect reactive power sharing has been observed. In recent years, advocates of distributed multiagent systems (MAS) have been broadly adopted as promising solutions for MG control and operations. Under this framework, the primary control and the secondary control can be efficiently integrated into a single distributed task.
