Résumé
[en] The increased use of renewable energy has highlighted the importance of energy storage systems to handle the intermittency of sources like solar power. This Master’s thesis titled "Optimizing Sustainable Homes with Home Batteries and V1G Technology: A Comparative Analysis" investigates the viability of two different technologies for residential photovoltaic (PV) integration, namely Home Batteries (HB) and Smart Charging (V1G) technology. The study’s primary aim was to evaluate these technologies' financial and environmental benefits and to understand the parameters affecting their performance in the context of sustainable homes.
Through simulation and modeling, this thesis analyzes the performance of HB and V1G when coupled with residential solar power systems. HB stores excess solar energy, reducing grid dependence and providing backup power. On the other hand, V1G technology integrates electric vehicles (EVs) as a mobile energy reserve, using smart charging strategies to optimize energy usage and contribute to grid stability.
The results revealed that HB consistently outperformed V1G in terms of self-consumption and cost-efficiency annually, primarily due to the constant availability of stored energy. In certain cases, V1G proved to be more cost-effective when specific parameters such as PV production, home base load, and individual driving behaviors were favorable.
It was observed that a household without any technology has an average 30\% self-consumption, but with the integration of V1G, it can be expected to increase to around 50\%, and with HB, it can further increase to approximately 80\%.
However, these results can vary for different households. Moreover, the initial investment for HB is significant and often has a payback period exceeding the battery lifespan. When considering the initial investment, V1G was consistently the best option in terms of overall savings. This is due to its significantly lower upfront costs compared to HB.
In conclusion, both HB and V1G technology serve as means to move towards more sustainable energy consumption in homes with PV systems. HB generally allow for higher energy self-consumption, while V1G may be a more cost-effective choice under certain conditions. This research emphasizes the need to consider the unique circumstances of each household in making the best technology selection. Continued advancements in the renewable energy sector, particularly in energy storage and management, pave the way for a sustainable and cost-effective future.
