Classification: CPC H  Y | IPC H

Claim 0:
1. A DC voltage grid, comprising:
an electrical conductor electrically interconnecting electrical components connected to the DC voltage grid, the electrical components comprising at least a consumer, an energy storage unit, and an energy source, and the electrical conductor having a variable DC grid voltage applied between parts of the electrical conductor;
an actuator receiving voltage from a voltage source that specifies the variable DC grid voltage via the actuator and supplying the electrical conductor with the variable DC grid voltage, wherein the actuator is configured to control and vary the DC grid voltage in order to describe a state of the DC voltage grid, wherein information about the state of the DC voltage grid is continuously transmitted during operation of the DC voltage grid to the electrical components connected to the DC voltage grid by the controlled and variable DC grid voltage, and wherein the DC grid voltage is adjusted by the actuator by either one or both of a first adjustment factor as a function of a state of charge of the energy storage unit or of a second adjustment factor as a function of a capacity utilization of the energy source; and
wherein the adjusted DC grid voltage is calculated by multiplying the voltage from voltage source that specifies the variable DC grid voltage by either one or both of the first adjustment factor or of the second adjustment factor.
