description This paper presents two expert systems designed to serve as a control center operator's assistant. The first is designed to assist operators in solving overload problems and the second is to assist in solving voltage problems. Both systems use the distribution factor concept to create indices for the decision-making process. A new improved technique to obtain the distribution factors is presented. That technique circumvents part of the problems introduced by the linearization implicit in the use of distribution factors and makes them suitable to be used to solve voltage problems. A 634-bus model of an actual electrical system and its interconnections is used so that the results can be realistically compared with the action that would be taken in the control center. Results are reached in a manner consistent with the operation of the control center and in a time frame that makes these expert systems feasible for real-time applications.
