Island & Microgrids

Island grids are an electrical power supply task with a small number of power generating plants and consumers. Island grids do not have a synchronous connection to a large network and therefore have to be able to provide all tasks necessary for long-lasting and safe operation on their own. Microgrids are similar, but also have the capability to
