Abstract

U ovom radu je razvijen model Carnotove baterije u MATLAB-u i Simulinku, te je projektirana vjetroelektrana snage 40-ak MW korištenjem programa WindSim. Cilj rada bio je simulirati integriranu proizvodnju električne energije iz vjetroelektrane s modelom Carnotove baterije kapaciteta 100 MWh kako bi se vršilo pohranjivanje energije kada je cijena električne energije niska i njena proizvodnja korištenjem Rankineovog ciklusa kada je cijena električne energije visoka.
Projektiranje vjetroelektrane uključivalo je: analizu mjernih podataka s mjernog stupa Bili Brig, modeliranje terena i pokrova lokacije, izbor optimalnih lokacija za vjetroagregate i procjenu njihove ukupne proizvodnje energije.
Uz razvijeni model Carnotove baterije, dodatno su u simulaciju uključeni model generatora pare na otpadnu toplinu i električni grijač. Također je napravljen proračun Rankineovog ciklusa u stacionarnom stanju kako bi se izračunala iskoristivost cijelog procesa.
Prvo su prikazani rezultati simulacije dinamike sustava Carnotove baterije bez integrirane vjetroelektrane kako bi se ispitalo osnovno ponašanje sustava. Nakon toga, rezultati uključuju dinamiku s integriranom proizvodnjom vjetroelektrane u 1. i 8. mjesecu 2022. godine.
Iskoristivost pohrane električne energije u Carnotove baterije dostiže vrijednost od 30,6 %.

Abstract (english)

In this paper, a model of the Carnot battery was developed in MATLAB and Simulink, and a wind farm with a capacity of approximately 40 MW was designed using the WindSim software. The aim of the paper was to simulate the integrated production of electricity from the wind farm with the Carnot battery model with a capacity of 100 MWh to store energy when electricity prices are low and produce it using the Rankine cycle when electricity prices are high.
The design of the wind farm included the analysis of measurement data from the Bili Brig measurement mast, modeling the terrain and land cover of the location, selecting optimal locations for wind turbines, and estimating their total energy production.
In addition to the developed Carnot battery model, the simulation also included a model of a heat recovery steam generator and an electric heater. A stationary state calculation of the Rankine cycle was also performed to determine the efficiency of the entire process.
First, the results of the simulation of the Carnot battery system dynamics without the integrated wind farm are presented to examine the basic behavior of the system. After that, the results include the dynamics with the integrated wind farm production in January and August 2022.
The energy storage efficiency of the Carnot battery reaches a value of 30.6%.
