Modeliranje porabe električne energije gospodinjskih odjemalcev

KOZINC, PRIMOŽ (author), Blažič, Boštjan (mentor)

Zaradi vse večjega vključevanja razpršenih virov v distribucijska omrežja z nestalno proizvodnjo lahko pride do obratovalnih težav, saj se lahko poruši ravnovesje med proizvodnjo in porabo električne energije. Zaradi tega se pojavlja vse večja potreba po natančnejšem modeliranju delovanja distribucijskega omrežja. V diplomskem delu je s pomočjo programskega orodja Matlab predstavljen postopek modeliranja napovedi porabe električne energije gospodinjskih odjemalcev. Sestavili smo dinamičen model gospodinjstev, ki nam omogoča izvedbo podrobnejše analize modeliranja porabnikov. V prvem delu so predstavljene najpogosteje uporabljene naprave v gospodinjstvih, obravnavana pa je tudi odvisnost njihove uporabe od aktivnih družinskih članov in verjetnosti vklopa skozi dan. V drugem delu so predstavljeni rezultati, pridobljeni z modelom, vključno s primerjavo z rezultati meritev, opravljenih v Žireh. Končna primerjava podaja potrebno oceno zanesljivosti in kakovosti izdelanega modela.

Abstract

The increasing integration of diffuse sources with variable generation into distribution power grids can lead to operating issues due to the collapse of balance between the generation and the consumption of electrical energy. Therefore, there is an increasing need of more accurate modelling of distribution network. The thesis presents the procedure for modelling the prediction of power consumption in low voltage networks with the help of Matlab programme. A dynamic model of households enabling a detailed analysis of consumers has been created. In the first part the most commonly used devices in households are presented and their dependence between active family members and probability of activation throughout the day is discussed. In the second part the results acquired with the model are presented and compared with the results of measurements performed in Žiri. The final comparison provides the necessary assessment of reliability and quality of the constructed model.
