Method for controlling a thermal power plant using regulated valves

Electricity generation thermal power plant, said plant comprising at least one heat source to supply thermal energy to a working fluid circulation circuit, said circuit comprising at least:

• a high pressure turbine mechanically connected to an electricity generator,
• a high pressure regulating valve controlling steam supply to said high pressure turbine from a high pressure superheater associated with a high pressure storage tank, the fluid supply to said high pressure storage tank originating from a high pressure steam generator being controlled by a high pressure supply valve,
• wherein said power plant comprises means for controlling the high pressure regulating valve and means for controlling the high pressure supply valve, and in that it said power plant is configured such that when a demand for additional electrical power is received,
• the opening of the high pressure regulating valve is increased
• the opening of the high pressure supply valve is reduced.
