Analysis of the Wind Generation Impact on Inertial and Primary Frequency Response of the Croatian Electric Power System

摘要

This research examines the impact of wind penetration in the Croatian power systems on system frequency stability. The main focus of the research is the simulation of system frequency response on the mathematical model of Croatian power system. With these models the possibility of providing wind inertial response and primary frequency response will be examined. Characteristics of frequency response such as the value of frequency nadir, the steady-state frequency deviation and the rate of change of frequency will be compared for all investigated cases. This paper uses low-order system frequency response models to simulate power system frequency changes. Also, most of the block parameters are provided and are accurately calibrated to model "real life" processes. The models are developed and implemented in the MATLAB/Simulink and tested on "real life" case in Croatian power system.
