Stability Issues in Microgrids

This chapter introduces relevant concepts about stability issues in microgrids. First, general aspects related to microgrids, distributed generation, and stability are introduced. Stability classification in conventional power grids and the challenges emerging concerning stability in microgrids are discussed. Then, a brief literature review focusing on studies on stability impacts on MGs is presented. After this, some control strategies to improve the stability characteristics of the MGs are discussed. Then, microgrids hierarchical control and its design characteristics from a stability approach are presented. The chapter concludes with key findings and remarks.
