Abstract: Most consumers receive their electricity via electrical grids consisting of utility generation plants and transmission and distribution networks. In most highly developed and populated parts of the world, consumers receive their electricity continuously and reliably most of the time. Unfortunately, disruptions do occur for various reasons, and with significantly negative social, economic, and public safety impacts. In addition, modern utility rate structures can significantly impact electricity costs to consumers due to surcharges based on tiered and time-of-use pricing and peak demand charges. In lesser populated and/or more remote locations, electrical grids do not exist at all, and localized solutions are required.

Electric Microgrid
This lecture will discuss Microgrids as a solution to some of the challenges we face; we will explore definition of microgrid; types of microgrids; main elements of microgrids including DERs and DERMS; and review use case and value proposition examples. We will also explore steps required to design a microgrid and some of the simulation and modeling tools used.
