Problem description:	[[Objective::While electrification is a positive step toward decarbonization, minimizing the need for large-scale grid investments is crucial. One promising solution is the implementation of decentralized energy systems, which integrate local energy generation and storage to address grid capacity challenges. Decentralized energy systems offer both an environmental and socioeconomic benefit. Firstly, they reduce stress on the grid by shaving and shifting peak demand, thereby delaying or avoiding the need for expensive grid reinforcements [5]. Secondly, they empower consumers by reducing dependence on centralized systems and volatile spot prices. By relying on locally produced energy, consumers can lower their energy costs and gain greater control over their energy supply. This increased energy independence is particularly valuable in the face of natural disasters, geopolitical instability, and supply chain disruptions which is an increasing risk today. Solar photovoltaic (PV) systems and batteries are central components of decentralized energy systems. In recent years, these technologies have seen substantial price reductions, a trend expected to continue. Their affordability makes them viable for widespread adoption. However, the intermittent nature of solar power creates a mismatch between energy generation and demand, which must be addressed through energy storage solutions. This thesis will address the capability of thermal storage in boreholes, especially in addressing the summer/winter dilemma.]]

Red line

Your thesis should have a "red line", which is visible throughout the whole thesis. This means you should mention in the beginning of each chapter how the chapter contributes to the "goals of the thesis".

Use of scientific methods

A thesis follows a standard method:

describe the problem (problemstilling)
extract the challenges. These challenges should be measurable, e.g. method is too slow to be useful to voice handover.
Analyse technology with respect to challenges. Don't write & repeat "everything" from a certain technology, concentrate on those parts (e.g. protocols) which are of importance for your problem

References

Wikipedia is good to use to get an overview on what is happening. But there is not scientific verification of Wikipedia, thus you should use wikipedia only in the introduction of a chapter (if you use text from wikipedia). Use scientific literature for your thesis.
Scientific library is "at your hand", you can get there directly from UiO: [[How to get access to IEEE, Springer and other scientific literature -> Unik/UiOLibrary]]
I suggest that references to web pages, e.g. OASIS, W3C standards, are given in a footnote. Only if you find white papers or other .pdf documents on a web page then you refer to them in the reference section.

Evaluation of own work

Perform an evaluation of your own work. Revisit the challenges and discuss in how you fulfilled them. Provide alternative solution and discuss what should be done (or what could have been done).
