7 Conclusion

This chapter presents a brief overview of microgrid technology, as well as opportu-
nities and challenges associated with it. A number of architectures proposed in lit-
erature have been categorized in three main categories and discussed in brief. These
microgrids operate with renewable energy sources of very unpredictable nature, and
therefore suitable robust control strategies are required. Different control strategies are
reviewed in this chapter. This chapter will help readers to have a glimpse of microgrid
technology and firsthand knowledge of architecture and associated control.
