Coupling between knowledge-based and algorithmic methods

The integration of knowledge-based techniques with traditional algorithmic software is discussed. Typical problems in power system planning and operation are better solved when the two techniques are combined. Functional aspects of a hybrid problem solving strategy are described and illustrated by two examples from power system operation. Available methods for practical implementation are reviewed. Sample applications from the literature are used to illustrate different approaches to hardware and software integration. Some of these applications have been successfully integrated with existing systems in operational environments. Future energy management systems based on an open architecture are likely to make it easier to integrate knowledge-based systems. Still, software integration issues continue to be a challenge. Particular problems are: automation of complex tasks by intelligent coordination, development of highly flexible software organizational schemes, and methods for easy data exchange between applications based on different software paradigms
