Microgrid

A microgrid is a localized grouping of electricity sources and loads that normally operates connected to and synchronous with the traditional centralized grid (macrogrid), but can disconnect and function autonomously as physical and/or economic conditions dictate.[1]

A formal definition from the U.S. Department of Energy Microgrid Exchange Group[2] states: A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode.

Examples

Les Anglais, Haiti

A wirelessly managed microgrid is deployed in rural Les Anglais, Haiti.[3] The system consists of a three-tiered architecture with a cloud-based monitoring and control service, a local embedded gateway infrastructure and a mesh network of wireless smart meters deployed at 52 buildings.

Non-Technical Loss (NTL) represents a major challenge when providing reliable electrical service in developing countries, where it often accounts for 11-15% of total generation capacity.[4] An extensive data-driven simulation on 72 days of wireless meter data from a 430-home microgrid deployed in Les Anglais, Haiti has been conducted to investigate how to distinguish NTL from the total power losses which helps energy theft detection.[5]
