A method in connection with power plants connected to form a network, the network comprising a central unit (1) and the power plants (2) comprising a measurement and control unit, wherein the central unit comprises time series models of the power plants connected to form the network, the method comprising the steps of collecting (3) measurement data to the central unit from the power plants connected thereto; storing (5) the measurement data in a database of the central unit; updating (7) the power-plant-specific time series models stored in the central unit; drawing up (8) at the central unit power-plant-specific forecasts of the energy need on the next time period; retrieving (9) price information relating to the next time period from energy exchanges, or the like, to the central unit; computing (11) at the central unit optimum power levels for the generating units on the basis of load and price forecasts; and transmitting (12) control commands to the generating units. |
