A computer-based method and a computing device (3) for automatically providing control parameters for a plurality of coal mills (5a, 5b, 5c) supplying coal powder for example to a furnace (7) of a power plant is proposed. The method comprises (a) acquiring a multiplicity of operation variables indicative of a load of an individual coal mill for each of the coal mills by measuring actual parameters indicative of a coal mill operation; (b) acquiring a demand variable indicative of a coal demand from the plant; (c) supplying the acquired multiplicity of operation variables and the demand variable to a computing system; (d) calculating the control parameters based on the multiplicity of operation variables and the demand variable using a multivariable calculation algorithm, in particular a model predictive algorithm; (e) providing the calculated control parameters for controlling an operation of each coal mill individually; and (f) repeating steps (a)-(e). Due to using a multivariable calculation algorithm for calculating the control parameters taking into account a multiplicity of actual operation variables and demand variables from components of the power plant, the coal grinding load may be optimally allocated to each individual coal mill thereby enabling high efficiency and high velocity ramp up or ramp down of the plant operation.
