Vrednotenje delovanja sončne fotonapetostne elektrarne za samooskrbo

Miklič, Žiga (author), Topič, Marko (mentor)

Sončna energija je praktično neusahljiv vir energije in spada med obnovljive vire energije. Sončna elektrarna je sistem, ki energijo sončnih žarkov pretvori v električno energijo. V diplomski nalogi izpred dveh let, ki je bila štartna osnova za nadaljevanje v pričujoči magistrski nalogi, sem zasnoval, načrtal in izdelal sončno elektrarno nazivne izmenične moči 13,8 kVA za samooskrbo gospodinjstva. V magistrski nalogi sem za sončno fotonapetostno elektrarno nazivne izmenične moči 13,8 kVA za samooskrbo opravil analizo delovanja elektrarne za obdobje dveh let in izvedel vrednotenje učinkovitosti gradnikov elektrarne na več različnih načinov. Meritve proizvedene in porabljene električne energije ter izbranih vremenskih parametrov, izvedene v juliju 2022, sem primerjal z meritvami izpred dveh let in primerjal kazalec učinkovitosti sončne elektrarne v izbranem časovnem obdobju. V nadaljevanju sem obravnaval koncepte prožnosti odjema s strani odjemalcev v luči samooskrbe, polnjenja električnih vozil ali hrambe energije ter pregledal pristope k dinamičnemu tarifiranju omrežnine in cene električne energije. Za konec sem predstavil še smernice za nadgradnjo sončne fotonapetostne elektrarne za samooskrbo iz OVE.

• Title: Evaluation of a solar photovoltaic power plant operation for self-consumption

Abstract

Solar energy is an abudant source of energy and one of the renewable energy sources. A solar power plant is a system that converts the energy of the sun's rays into electricity. In the bachelor diploma thesis from two years ago, I designed, planned and manufactured a solar photovoltaic power plant with a nominal alternating power of 13.8 kVA for household self-suply. In the master thesis, I present a description of the solar photovoltaic power plant with a nominal AC power of 13.8 kVA for self-supply and the analysis of the power plant operation for a period of two years, followed by an evaluation of the efficiency of the building blocks of the power plant in several different ways. In July 2022, I compared the measurements of produced and consumed electricity and selected weather parameters with the measurements from two years ago. I compared the efficiency indicator of the solar power plant in the selected time period. I discuss concepts of flexibility of consumption by consumers in the light of self-suply, charging of electric vehicles or electrical energy storage, and review approaches to dynamic tarifs for grid charges and electricity prices. Finally, I also present the guidelines for possible upgrades of the solar photovoltaic power plant for self-suply.
