Development of the Polish Power Exchange as a Management System in Terms of Control Theory and Systems Engineering

The paper presents the results of research concerning the Polish Power Exchange as a management system, obtained using the data quoted on the Day-Ahead Market. As a result of identification, 24 arx discrete linear parametric models of MISO type were obtained (with 24 input quantities and single output quantities). Input quantities are the volume of electrical energy supplied and sold in each hour of the 24-hour day, and output quantities are average prices weighted by the volume of electrical energy obtained in each hour of the 24-hour day. These models were converted to continuous parametric models, and further into continuous models in the states space. The results of the discussion were also presented, including the interpretation of state variables, as well as the model's parameters and the conclusions together with directions for further research.
