2 MicroGrid? A group of interconnected loads and distributed energy resources (DER) with clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid [and can] connect and disconnect from the grid to enable it to operate in both grid-connected or island mode.

11 summary e average efficiency of all coal power stations in the orld currently stands at ~31%, (Hans-Dieter Schilling Energie-Fakten). The existing SuperGrids designed 40 to 60 years ag are expanded upon year in year out have onerous technical requirements, if we were to design a grid f scratch today with the innovation available, we wou so very differently. An isolated MicroGrid connected to a SuperGrid de with today's innovation can be more than ~80% mo reliable, operate ~50% more efficiently and cost ~30 less than the equivalent SuperGrid expansions of to An Energy Cell or MicroGrid will look like a large D battery to the SuperGrid, it will participate in the who / retail energy market deriving an untapped revenue stream, whilst optimizing the peak demand cycle ac our networks. NSW's solar researchers have converted over 40% of e sunlight hitting a solar system into electricity, the ghest efficiency ever reported. attery storage at today's prices will only provide stability grid-forming in a MicroGrid as prices come down, these ttery systems will expand to offer load shifting. istributed Gas / Diesel Generators + their CHP energy nversion, is up to 85% efficient when local to the load. ybrid Generation, with Solar will offset the cost of fuel ring its operating lifetime by up to 30% if Wind is cluded, this could exceed 70%.
