In a power plant including a plurality of parallel-operated generating elements supplying electricity and steam, boilers and turbines are controlled in an optimum condition depending on the successive changes of the demand for steam and electricity by: estimating parameters of characteristics and state of the generating elements, which cannot be directly measured, among parameters of the generating elements needed for calculation of the optimum load distribution for each of the generating elements, based on a physical model of each of the generating elements and an input process state quantity; and controlling each of the generating elements by determining an optimum load distribution for the each of the generating elements while using the estimated parameters of the each of the generating elements, to minimize a total cost of the power plant depending on the successive changes of the demand for steam and electricity.
