Abstract

This chapter presents a local-distributed control for hybrid series–parallel microgrid in islanded mode. A number of local converters in series type are controlled as a consistent string by distributed cooperative control without a central controller, and power demand among parallel strings is shared in a decentralized manner. Hence only an in-string sparse low-bandwidth communication (LBC) network is sufficient for limited information exchange among local converters. With the control, the frequency synchronization and proper power sharing can be achieved under both the resistive-inductive (RL) and resistive-capacitive (RC) loads. Moreover, the reliability and redundancy of hybrid series–parallel microgrid are improved, and the communication costs are reduced. The overall system stability is analyzed and reasonable design ranges of control parameters are given. Finally, the feasibility and effectiveness of the proposed solution are verified by simulation tests.
