ABSTRACT:
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.
