Potential of artificial neural networks in power system operation

The potential applicability of artificial neural networks (ANNs) to electric power systems, with an emphasis on aiding dispatchers with decision-making (particularly with decisions relating to power system security), is discussed. Examples illustrate how ANNs can alert dispatchers to security threats due to possible constraint violations, unstable dynamics, and uncertain loads. The problems that must be overcome before an ANN dispatcher's aid is realizable are reviewed.<>
