Nonconvex optimization by fast simulated anealing
Article Abstract:
The simulated annealing technique presented is faster than conventional simulated annealing. The new technique is applied to a multisensor location and tracking problem. The technique, called Fast Simulator Annealing (FSA) employs a semi-local search strategy using the infinite variance probability density to generate a random process that more often allows large steps in phase space than the strictly local step strategy using a Gaussian probability. The larger steps are a time savings. An example is presented of the application of the new technique and a conventional technique applied to the problem of locating and tracking multiple, indistinguishable targets using noisy, bearing-only, data with both missed directions and false alarms.

Security analysis and optimization
Article Abstract:
Current power system control processes which are needed to maintain specified security levels at a minimum cost, increasingly depend upon-line computer security analysis and optimization. There are two principle computational tools in this field: contingency analysis (extensive 'what if' simulations), and special operations-oriented versions of optimal power flow (a major extension to he conventional dispatch calculation). Current formulations and techniques are reviewed and other areas of difficulty and challenge are pointed out.

Optimization-based methods for operations scheduling
Article Abstract:
The operations scheduling problem in electric power systems and mathematical formulations to the problem along with recent advances in optimization-based solutions are discussed. Short term aspects of the problem on the order of one week are focussed on. Emphasis included solution methods, unit commitment, short-term hydro scheduling, and hydro-thermal coordination problems.
