Fuzzy logic and its application in electric power sector or system

Electric power systems are one of the most complex in our civilisation. Aside from many factors describing the operation of the system there are different external influences that more or less influence the behaviour of the observed system. Laws describing these systems are often neither linear nor finally defined. Because of its complexity, sometimes even non-defined as well as for the need of expert knowledge in a certain field fuzzy logic has found application in solving problems of an electric power sector. Fuzzy logic with its application of fuzzy variables can catch different non-determination and be an auxiliary tool to engineers in many parts of an electric power company.
