SAFE AND RESILIENT ENERGY DISTRIBUTION FOR A HIGHLY EFFICIENT MICROGRID

A microgrid with a high voltage direct current (HVDC), source, a high voltage alternating current (HVAC) source respectively, for efficiently and safely distributing power to decentralized loads, includes: at least a main or central HVDC, respective HVAC, power supply connectable in input to an AC grid and in output to a main DC, respective AC, distribution network, and loads system in output, having an energy reserve means, and including a main fault isolator or main FI; the main DC, respective AC, distribution network, and loads system including a maintrunk bus, and subtrunks buses and/or front end local loads cells connected in parallel to the maintrunk bus, and including, at each branching of a subtrunk and a load or of a subtrunk of order (N−1) and a subtrunk of order N, a local fault isolator or local FI; and a smart main controller including microcontrollers, for smartly operating adjacent local FIs.
