What is a hybrid microgrid?
Hybrid microgrids use two or more energy sources, for example, solar and wind power, to generate their energy. This energy is then stored in a battery system. A hybrid system can be grid-connected or islanded depending on the requirements.
When did standardized protocols become available for reconnection of microgrid systems?
It wasn’t until the IEEE approved standard 1547.4 in 2011, that standardized protocols became available for safe intentional islanding and reconnection of microgrid systems. IEEE 1547.4 includes guidance for planning, design, operation, and integration of distributed resource island systems with the larger utility grid.
When was the first microgrid built?
According to Pike Research, the first “modern industrial microgrid in the United States was a 64 MW facility constructed in 1955 at the Whitling Refinery in Indiana,” but most people are not aware the concept is much older. The microgrid concept dates back to the beginning of our industry.
Are energy storage systems a barrier to microgrid adoption?
However, one of the key barriers to more widespread adoption of microgrid technologies is the cost of energy storage systems (ESSs) , which are used in nearly all microgrids for load balancing and renewable energy integration, among many other uses .
