Mikrovõrk

Mikrovõrk is a term used to describe a small, localized electrical grid that can operate independently from the main national grid or in conjunction with it. These microgrids are designed to provide electricity to a limited geographical area, such as a university campus, a hospital, a business park, or a community. A key feature of mikrovõrks is their ability to disconnect from the larger grid during outages, maintaining power supply to their connected loads. This resilience is achieved through the use of local generation sources, such as solar panels, wind turbines, or combined heat and power (CHP) systems, and often incorporates energy storage solutions like batteries.

The control and management of a mikrovõrk are typically handled by a dedicated control system that can monitor power generation, demand, and grid connection status. This system ensures stable operation whether the mikrovõrk is islanded or connected to the main grid. Mikrovõrks offer several advantages, including improved reliability and power quality for connected users, the integration of renewable energy sources, and the potential for reduced energy costs through optimized local generation and consumption. They can also contribute to grid stability by providing ancillary services to the larger network. The development and deployment of mikrovõrks are seen as a significant trend in modernizing energy infrastructure and enhancing energy security.
