Abstract	Disertacija se bavi razvojem metodologije vrednovanja pomoćne usluge regulacije napona i jalove snage putem tržišnog mehanizma nadoknade troškova izvora jalove snage uz istovremeno minimiziranje troškova operatora prijenosnog sustava i održavanje sigurnosti EES-a, kojeg je moguće jednostavno uklopiti u sustav vođenja EES-a. Metodologija vremenski obuhvaća djelovanje tržišta jalovom snagom u fazi kratkoročnog planiranja i temelji se na podjeli EES-a u naponske zone korištenjem metode električnih udaljenosti, čime se uspostavljaju lokalna tržišta jalovom snagom. Dvo-razinskim optimizacijskim algoritmom provodi se proračun optimalnih tokova snaga s ciljem određivanja tržišne cijene jalove snage unutar svake naponske zone u prvom koraku, te optimalnog naponskog plana EES-a u drugom koraku. U drugom optimizacijskom koraku predstavljena je složena funkcija cilja koja objedinjuje kriterij minimalnih troškova nabave energije za pokriće gubitaka u mreži te kriterij minimalnih troškova nabave jalove energije. Metodologija je testirana na IEEE 39 test mreži te na modelu hrvatskog EES-a, za scenarije maksimalnog i minimalnog opterećenja obje razmatrane mreže. Rezultati opravdavaju predloženi pristup, a uočeni problemi ujedno su i smjernice za budući razvoj i moguća poboljšanja predložene metodologije.
Abstract (english)	Dissertation involves development of methodology for evaluation of voltage control ancillary service incorporating market mechanism for reactive power sources cost compensation, including simultaneous system operator's cost minimization and power system security maintenance, that can be easily incorporated into power system control. Methodology comprises reactive power market operation in the short-term planning phase, based on division of power system into voltage zones using the electrical distance method, where local reactive power markets are established. Two-stage optimisation algorithm uses optimal power flow to determine the reactive power market price in every voltage zone in the first optimisation stage, and optimal voltage plan in the second optimisation stage. In the second optimization stage a complex objective function is used that incorporates two objectives: minimal cost for procurement of energy for covering transmission losses and minimal cost for procurement of reactive energy. Methodology is tested on IEEE 39 bus test system and on Croatian power system model, including maximum and minimum load scenario for both analysed networks. Results are justifying the proposed approach, and perceptible problems are at the same time guidelines for further development and possible improvements of the propsed methodology.
