Abstract

This chapter briefly discusses the various control principles and techniques for the primary and secondary control of microgrids. More specifically, proper active and reactive power-sharing among the distributed energy resources is discussed under the primary control aspect, whereas dynamic power-sharing ratio modification and regulating the voltage and frequency are discussed under the secondary control. A modified control technique is also discussed for the BESs in comparison to DERs. The advantages and limitations of each suggested technique are discussed and demonstrated by some simulation-based examples. The chapter has also discussed the small signal stability of microgrids, focusing on the most important states of the system, which have a dominating factor in making the system unstable.
