A digital computer system is employed to produce power system control. The computer system employs an economic dispatch program, a unit selection program and a tie line interchange program to determine off line a tie line schedule and unit commitments needed to satisfy economically and safely a load forecast over a selected time interval such as 24 hours. In on line closed control loop operation, the computer system employs a load and frequency control program which uses the tie line schedule and other quantities in determining area control error. The control program develops a system error representation which reflects a smoothed present and anticipated area control error. The system error representation is distributed into individual generator plant control signals under economic dispatch program and unit selection program control and under constraint of programmed plant limits to assure that each generation move is error correcting as well as optimally economic.

The method of, operating a power complex to supply a system load and non-conforming loads; said power complex having a power generating network including a plurality of power generators and tie-lines to neighboring power generating networks, the said method comprising deriving from said complex at relatively short intervals, of the order of one second, signals indicative of: 1. the load power supplied by each of said generators, 2. the frequency of the power of said load, 3. the power drawn by said tie-lines, 4. the power drawn by said non-conforming loads; the said method also comprising converting said signals into digital values, separating said digital values into separate items of data each item corresponding to said items 1, 2, 3 and 4 respectively; storing said separate items; computing from a plurality of said items derived during a plurality of said intervals and the past history of operation of said complex, an area-requirement error which is based, for each computator on the anticipated trend of variation of said system load following the latest of said intervals, responsive to said area-requirement error producing electrical generator resetting signals to reset econOmically each power generator of said plurality of generators to the extent required to reduce said error to zero, and supplying said resetting signals to said generators to reset said generators as aforesaid.
