Content SummaryThe optimal operational planning of an electric power system is based upon a priority list of all units participating to the power production. The elaboration of the units priority list is a critical task and is based on both, objective criteria (units’ condition, load demand, etc.) and the operators’ experience. The fuzzy approach applied to this category of problems gives more reliable results compared to conventional methods. The objective of this paper is to demonstrate the use of a fuzzy relational database model for manipulating the data required for the priority classification of the units for optimal power unit commitment planning. The priority classification list is formed incorporating criteria like operational cost, safety requirements, environmental impacts, operation condition history, maintenance scheduling and alternative supply availability. Fuzzy linguistic terms for their definitions along with fuzzy inference allow the operators expertise to be exploited. The proposed database undertakes the representation and handling of the above fuzzy information and additionally permits the user to specify the precision with which the conditions involved in a query are satisfied. In order to illustrate the behavior of the model a case study is given for the autonomous power system of the Crete Island.en
