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. 2 A microgrid can operate in either grid-connected or in island mode, including entirely off-grid. . NLR has been involved in the modeling, development, testing, and deployment of microgrids since 2001. It operates normally in connection with the main power grid but can also work independently during power outages or grid failures. A microgrid can connect and disconnect from the grid to enable it to operate in both. . Microgrids are a pioneering concept in energy distribution and management, characterized by small-scale, localized power systems that can function independently or alongside the main electrical grid. Unlike traditional centralized grids, microgrids are designed to serve specific areas or. .

Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in, and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 1960s to 1980s,.
