Claim 0:
1. A power system, comprising:
a number (N) of prime movers having a variable speed (ni), configured to generate mechanical power by providing a mechanical drive force, wherein the number (N) of prime movers is one or more;
at least one generator configured to receive the drive force of at least one of the number (N) of prime movers) to generate an electrical power, wherein the at least one generator is configured to couple with a power grid, and the power grid is configured to transmit the electrical power having a frequency (f) and to couple with an external load;
at least one controller configured to control the variable speed (ni) to a speed reference (nref,i) of at least one of the number (N) of prime movers and/or the frequency (f) of the power grid;
at least one energy storage device configured to, at least temporarily, provide to the external load and/or receive from the external load, the electrical power via the power grid;
at least one first measuring device configured to provide at least one first signal to the at least one controller to determine an amount of electrical power (ΣPG,i) to be generated by the at least one generator to meet a power requirement (Pload) the external load;
wherein the at least one controller is configured to receive the at least one first signal and to influence the control of the variable speed (ni) of the at least one of the number (N) of prime movers or the frequency (f) of the power grid taking into account the at least one first signal to change the mechanical power generated by the at least one of the number (N) of prime movers such that the electrical power provided by the at least one generator approaches the power requirement (Pload) the external load in situations where the power requirement (Pload) the external load is at least partially provided by the at least one energy storage device, and
wherein the at least one controller is configured to control the variable speed (ni) of the at least one of the number (N) of prime movers and, at least temporarily, apply an additive or multiplicative feed-forward-control of actuators of the at least one of the number (N) of prime movers proportional to the received at least one first signal to influence the mechanical power produced by the prime mover, wherein the at least one first signal is representative for the electric power provided by the at least one energy storage device to the power grid.
