Abstract
This master thesis investigates the potential and limitations of local electricity sharing in residential distribution networks by analysing the correlation between local photovoltaic (PV) generation and electricity consumption in existing rural low-voltage grids. The study is based on quarter-hour resolution measurement data from 2025 provided by E.ON, including consumption and production data from individual households and five substations. The objective was to evaluate how local PV generation affects substation power profiles, to what extent PV production coincides with neighbouring households’ electricity demand, and what the potential for electricity sharing is in Sweden as well as what hinders it at the moment. A quantitative... (More)
This master thesis investigates the potential and limitations of local electricity sharing in residential distribution networks by analysing the correlation between local photovoltaic (PV) generation and electricity consumption in existing rural low-voltage grids. The study is based on quarter-hour resolution measurement data from 2025 provided by E.ON, including consumption and production data from individual households and five substations. The objective was to evaluate how local PV generation affects substation power profiles, to what extent PV production coincides with neighbouring households’ electricity demand, and what the potential for electricity sharing is in Sweden as well as what hinders it at the moment. A quantitative methodology was applied on both system and household level, including simulated scenarios with battery energy storage. The results show limited overall
impact on substation power profiles but clear seasonal variations in coincidence between production and consumption. The aggregation factor varies from around 0-10% during the winter to up to 50% during the summer. Battery storage improves self-consumption and local electricity sharing potential. The results also show that electricity sharing already occurs physically in today’s electricity grid, but that economic and regulatory structures to enable virtual sharing between households within existing grid infrastructure are still lacking.

Abstract (Swedish)
Detta examensarbete undersöker potentialen och begränsningarna för lokal eldelning i småhusområden genom att analysera sambandet mellan lokal solcellsproduktion och elkonsumtion i befintliga lågspänningsnät på landsbygden. Studien baseras på kvartsupplöst mätdata från E.ON Energidistribution från år 2025, med konsumtions- och produktionsdata från enskilda hushåll och fem nätstationer. Målet var att utvärdera hur lokal solelsproduktion påverkar nätstationernas effektprofiler, i vilken utsträckning solelsproduktionen sammanfaller med angränsande hushålls elbehov, och vilken potential det finns för eldelning i Sverige samt vad som hindrar den i nuläget. En kvantitativ metod tillämpades på både system- och hushållsnivå, inklusive simulerade... (More)

Målet var att utvärdera hur lokal solelsproduktion påverkar nätstationernas effektprofiler, i vilken utsträckning solelsproduktionen sammanfaller med angränsande hushålls elbehov, och vilken potential det finns för eldelning i Sverige samt vad som hindrar den i nuläget. En kvantitativ metod tillämpades på både system- och hushållsnivå, inklusive simulerade scenarier med batterilagring. Resultaten visar begränsad påverkan på nätstationernas övergripande effektprofiler men tydliga säsongsvariationer i sammanlagringen mellan produktion och konsumtion. Sammanlagringsfaktorn varierar från cirka 0-10\% under vintern till upp till 50\% under sommaren. Batterilagring förbättrar egenanvändningen av el och potentialen för lokal eldelning. Resultaten visar även att eldelning redan sker fysiskt i dagens elnät, men att ekonomiska och regulatoriska strukturer för att möjliggöra virtuell delning mellan hushåll inom befintlig nätinfrastruktur fortfarande saknas.
