Method for supplying energy in a local energy supply network

Abstract

A method for supplying energy in an energy supply network connectable to a higher-level energy supply network, wherein at least one participant includes an energy supply device having an inverter, includes: i) disconnecting the energy supply network from the higher-level energy supply network; ii) disconnecting all participants from the energy supply network; iii) determining master and slave inverters; iv) connecting participants having energy supply devices to the energy supply network; v) outputting an AC voltage by the master and slave inverters, the master prescribing frequency, voltage level and phase; vi) determining total energy available in the energy supply network and/or total power retrievable; vii) connecting a participant without an energy supply device to the local energy supply network after step v) depending on total energy, total power, expected power consumption and/or expected energy demand; and viii) isolating participants as required from the energy supply network to ensure network stability.
