Cluster analysis as a preliminary problem in neural modelling of the Polish Power Exchange

The work focuses on cluster analysis as a preliminary problem in neural model- ling based on the data quoted on the Day Ahead Market of the Polish Power Ex- change as a subsystem of the system of Towarowa Giełda Energii S.A. [Polish Pow- er Exchange]. The paper contains the results of literature research related to cluster analysis methods, description of possible applications of artificial neural networks SOM for mapping information on the volume of electrical power sold and prices ob- tained, description of possible applications of MATLAB and Simulink environment, and especially Neural Network Toolbox for mapping knowledge, and cluster analy- sis performed for selected data.
