Abstract
U ovome radu prikazana je primjena i usporedba P i PI algoritma u sekundarnoj regulaciji frekvencije i djelatne snage elektroenergetskog sustava. Prvo su opisane vrste regulacije u elektroenergetskom sustavu, te su navedene prednosti i nedostaci pojedinih razina regulacije frekvencije i djelatne snage, s naglaskom na sekundarnu regulaciju. Zbog mogućnosti usporedbe dvaju navedenih algoritama regulacije, razvijen je linearni model elektroenergetskog sustava. Prikazani model se sastoji od jednog regulacijskog područja, a svi njegovi sastavni dijelovi su detaljno opisani. Na linearnom modelu elektroenergetskog sustava izvršena su simulacijska ispitivanja. Napravljena je usporedba između P i PI algoritma sekundarne regulacije. PI algoritam se pokazao boljim od P algoritma iz više razloga. Glavni razlog je da u potpunosti kompenzira djelovanje poremećajne veličine, a osim toga oscilacije regulirane veličine nakon djelovanja poremećaja su osjetno manje, te je brzina regulacije veća.

This paper shows the application and comparison of a P and a PI algorithm in the load frequency control of a power system. Firstly, categories of control in the power system are described. Afterwards, the advantages and disadvantages of different levels of load frequency control, with an emphasis on secondary regulation, are presented. For the purpose of testing the two aforementioned control algorithms, a linear power system model is designed. The presented model is composed of a single control area and all of its components are explained in detail. The simulation was conducted on a linear power system model, on which the comparison of the P and PI control algorithm was obtained. The PI algorithm is superior to the P algorithm for several reasons. In other words, the main reason is that the PI algorithm not only fully compensates the effect of disorders, but the oscillations of the controlled variable are significantly less perceptible after the disturbances, and the controlling speed is greater.
