1. A method for setpoint adjustment of a setpoint for automatic power regulation, in a case of a solar thermal steam power plant having a non-adjustable primary heat source and an additional heat source, the method comprising:
for at least one prescribed instant during operation of the solar thermal steam power plant, ascertaining a present power range for the solar thermal steam power plant wherein the present power range of the solar thermal steam power plant is delimited by a lower control range limit and by an upper control range limit, and the present power range is determined using a present power from the non-adjustable primary heat source and using a power range from the additional heat source, wherein the lower control range limit takes account of a lower power reserve, having at least one reserve component for power regulation and/or frequency regulation, or primary and/or secondary frequency regulation, and wherein the upper control range limit takes account of an upper power reserve, having at least one reserve component for the power regulation and/or frequency regulation, or primary and/or secondary frequency regulation, and in the case of the setpoint adjustment, a presently prescribed setpoint of the solar thermal steam power plant is set in the present power range if the presently prescribed setpoint is outside the present power range. |
