ENERGY SOURCE FOR A DC VOLTAGE NETWORK, METHOD FOR OPERATING SUCH AN ENERGY SOURCE, DC VOLTAGE NETWORK WITH A PLURALITY OF SUCH ENERGY SOURCES, AND METHOD FOR OPERATING SUCH A DC NETWORK

摘要

The invention relates to an energy source (14) in the form of a direct current or direct voltage source for a direct voltage network (30) and to a method for operating same, wherein electrical energy can be fed to a connection point (12) of the direct voltage network (30) by means of the energy source (14). The energy source (14) has a control unit (32) for automatically switching the energy source (14) on or off. The energy source (14) is designed such that, before it is switched off, it ensures that it is not the last remaining energy source (14) at the connection point (12).
