Integration of artificial intelligence applications in the EMS: issues and solutions

This paper discusses the issues which must be addressed when integrating artificial intelligence (AI) and, in particular, expert system applications in an energy management system (EMS) environment. It is argued that these issues can be resolved by creating an environment which supports all the interfaces between the artificial intelligence (AI) applications and the EMS. This environment should also be responsible for maintaining a model of the power system common to all the AI applications. Once this environment has been created, AI applications can be easily "plugged" into the EMS. The design of such an environment, the operator decision environment, is described and studies of its implementation are provided to illustrate its flexibility.
