Modeling and simulation of the control- and the systems- inspired of the Polish Electricity Exchange

Abstract

The following paper contains selected results of research on modeling identification of Polish Electricity Exchange on the example of the dates quoted on the Day Ahead Market. In order to obtain a model of the Polish Electricity Exchange System in the beginning it was conducted to identify data for the period from January, 1 (2013) to December, 31 (2015). In the result discrete parametric model using arx method in MATLAB and Simulink environments with System Identification Toolbox was obtaining. The resulting model was converted to a continuous parametric model, and that one in turn into the state space model. On the basis of obtained equations of state and outputs, state variables and parameters of the selected model were interpreted, i.e. selected elements of the matrix' of the state space model. A block diagram was then constructed in Simulink, which was used for simulations and sensitivity studies using: sine, Dirac impulse and step function. Numerous interesting research results have been obtained, including the correctness of the development of the Polish Electricity Exchange.
