Abstract
Trend izkoriščenja obnovljivih virov energije se z vsakim letom povečuje. Skladno z njim narašča tudi število neodvisnih avtonomnih (otočnih) sistemov, kjer se energija shranjuje za kasnejšo uporabo. Pri projektiranju tovrstnih sistemov so glavnega pomena hranilniki energije. Na razpolago imamo številne tehnologije akumulatorjev, od katerih smo podrobno proučili trenutno najsodobnejše litij-železov fosfat akumulatorje (LiFePO4). Diplomsko delo obravnava model otočnega fotonapetostnega sistema za gospodinjski odjem s poudarkom na življenjski dobi hranilnika energije. S pomočjo podatkov o življenjski dobi LiFePO4 baterije, ki jo določajo življenjski cikli v odvisnosti od globin praznitev, smo v programskem orodju Matlab napisali kodo, s katero smo simulirali delovanje otočnega fotonapetostnega sistema za 20 let.

Title:Analysis of life cycles of an energy storage system for micro-grid electricity production
Abstract:
The trend of utilising renewable energy resources is increasing with each passing year, in line with a growing number of independent autonomous (stand-alone) systems, in which energy is stored for later use. Energy storage systems are one of the key elements when designing such systems. There are plenty of battery chemistry technologies available. The latest lithium iron phosphate (LiFePO4) battery chemistry is presented. The thesis discusses the example of an isolated photovoltaic system for households with emphasis on energy storage lifetime. Based on the lifetime data of an LiFePO4 battery, which is determined by life cycles, depending on the depth of discharge, we ran a simulation of battery performance for a period of 20 years. The simulation was performed using the Matlab program.

Keywords:stand-alone system, renewable energy, solar power, microgrid, energy storage
