Abstract
U ovom je radu predstavljen problem optimalnih tokova snaga u mrežama s obnovljivim izvorima energije te metode za rješavanje optimalnih tokova snaga. Koristeći PowerWorld programski paket, metodom linearnog programiranja izvršena je simulacija sastavljena od tri dijela. U prvom dijelu simulacije prikazan je optimalni rad EES-a s minimalnim troškom kao funkcijom cilja, a obnovljivi izvor kojeg predstavlja vjetroelektrana, radi prema planu. Drugi dio simulacije prikazuje proračunate optimalne tokove snaga i marginalne cijene u slučaju kada dođe do smanjenja izlazne snage vjetroelektrane u odnosu na prognoziranu vrijednost. Treći dio simulacije prikazuje promjenu tokova snaga i marginalne cijene u slučajevima kada dođe do povećanja izlazne snage vjetroelektrane u odnosu na prognoziranu vrijednost. Rezultati, osim optimalnih tokova snaga, pokazuju da pozitivno odstupanje izlazne snage vjetroelektrane utječe na smanjivanje marginalne cijene električne energije u sustavu, dok negativno odstupanje izlazne snage vjetroelektrane utječe na povećanje marginalne cijene električne energije u sustavu.
Abstract (english)
This paper presents the problem of optimal power flows in the network with renewable sources of energy, and methods for solving optimal power flows. Using PowerWorld software and the linear programming method three part simulation is completed. The first part of the simulation shows the optimum operation of the power system with a minimum cost as an objective function. Renewable sources represented by the wind power plants are in operation according to plan. The second part of the simulation shows optimal power flow and marginal cost calculation when the wind power output decreases in relation to the predicted value. The third part of the simulation shows power flow and marginal cost calculation when the wind power output increases in relation to the predicted value. The results, in addition to optimum power flows, show that the positive deviation of the wind power output affects the reduction of the marginal cost of electricity in the system, while the negative deviation of the wind power output influences the increase in marginal cost of electricity in the system.
