Identification modeling of Polish electric power exchange

This paper contains selected results of identificat on modeling of Polish Electric Power Exchange (EPE). In order to obtain EPE s ystem model it was performed identification based on figures of EPE’s Day-Ahead Market. During performing identification process, parametric arx model in Sys tem Identification Toolbox environment was utilized. Generated EPE parametric mode l has been further used for performing simulation tests and realization of susc eptibility testing. Suitable models were implemented in Simulink software. As a result of simulation and susceptibility testing, many interesting findings has been deliver ed.
