Abstract [en]

As the world moves away from fossil fuels, microgrids have garnered attention for their ability to aid the deployment of sustainable energy alternatives. Residential microgrid technology has proven to be a useful aid in the design of the power grid of the future. As society moves towards more renewable energy, more sophisticated energy solutions are required. This paper proposes a modeling approach for a residential hybrid AC/DC microgrid using Matlab and Simulink. The system consists of a photovoltaic (PV) system for DC generation, battery storage, and the potential for grid connection to enable reliable and efficient power. The paper discusses the modeling process and performance during various operating conditions. Simulation results showthe system's performance in terms of power generation, and storage as well as the impact of factors such as solar irradiation levels. The proposed model could be a valuable tool for further study and optimization for residential hybrid AC/DC microgrid systems.

Abstract [sv]

I takt med att världen rör sig från fossila bränslen har microgrids fått mycket uppmärksamhettack vare deras förmåga att smidigt leverera förnybar el. Microgrids för privata bostäder harvisats vara förmånliga vid design av framtidens elnät. I och med att samhället rör sig i alltsnabbare takt mot förnybar energi krävs mer sofistikerad elnätsteknologi. Denna rapport föreslåren modelleringsmetod för en hybrid AC/DC microgrid i skala anpassat för en villa eller mindrebostadshus. Systemet består av solceller för generering av DC-effekt, batterisystem samtförmågan att koppla sig mot det centrala elnätet för pålitlig och effektiv el. Rapporten diskuterarmodelleringsprocessen och prestandan under olika driftfall. Simuleringsresultaten visarsystemets prestanda i termer av effektgenerering, lagring samt effekterna av faktorer sominstrålningsnivå. Den föreslagna modellen kan vara ett värdefullt verktyg för vidare studier samtoptimering för hybrida microgridsystem i mindre skala.
