Claim 17:
18. A method to control at least one prime mover having a variable speed (ni), wherein the at least one prime mover is configured generate a mechanical drive force to drive at least one generator to generate an electrical power that is provided to a power grid, wherein the power grid is coupled to an external load and at least one energy storage device, wherein the at least one energy storage device is configured to at least temporarily provide electrical power to the power grid, wherein in situations when a power requirement (Pload) of the external load is at least partially provided by the at least one energy storage device, the method comprises:
receiving at least one first signal at a controller to determine an amount of electrical power (PG,i) to be generated by the at least one generator to meet a power requirement (Pload) of the external load, 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;
controlling the variable speed (ni) of the at least one prime mover or a frequency (f) of the power grid in dependence on the at least one signal to change a mechanical power generated by the at least one prime mover such that the electrical power provided by the at least one generator approaches the power requirement (P load) of the external load; and
applying, at least temporarily, an additive or multiplicative feed-forward-control of an actuator of the at least one prime mover proportional to the received at least one first signal to influence the mechanical power generated by the at least one prime mover.
