One of the major challenges that the energy system is facing is how 100% renewable electricity generation should be designed and controlled. So far, utility-scale solar photovoltaic (PV) parks, have dominated the international market and is expected to grow in Sweden. In order for this expansion to thrive it needs to be done in a resource and system-efficient way. In this study, a methodology for a utility-scale solar guide (from Swedish 'Solbruksplan') is developed. This is done through electrical grid simulations and geographical analysis in order to find strategic locations for PV parks, without grid reinforcements, using Herrljunga municipality as a case study. The electrical grid is analyzed through power flow simulations and the geographical assessment is done using multi-criteria analysis (MCA) with a Boolean approach. Three different sizes of PV parks, 1, 3, and 5 MW, were simulated and assessed. The results show that 8.6% of the total area in the municipality, or 78,500 square meters per substation, is suitable for locating 1 MW PV parks. The majority of the grid’s substations (about 90%) also have enough capacity for a PV park of 1 MW. Furthermore, parts of the grid can host PV parks of 3 and 5 MW, but limited to the proximity of the urban areas. However, 3 and 5 MW PV parks are not suitable due to limited land availability in urban areas. The results highlight that a utility-scale solar guide can be used to effectively identify possible areas for PV parks, considering geography and grid capacity. Hence, it can function as a tool for utility companies, municipalities, PV companies and land-owners to find resource and system-efficient locations for PV parks. / Solbruksplaner för system- och resurseffektiv utbyggnad av solelproduktion

Energimätning och övervakning kan bidra till minskad energiförbrukning genom att hjälpa en användare att ta beslut över energianvändandet. Valet av examensarbete gjordes p.g.a. behovet att ge användarna möjlighet att påverka sin energiförbrukning och övervaka sina elprodukter. Ett koncept togs fram där toppvärden på spänning och ström, effektfaktor, spänning-ens vågform, aktiv, reaktiv och skenbar effekt mättes. Samtliga värden skickades till en server som lagrade informationen och innehöll en hem-sida för presentation. Användaren kunde därefter ta beslut om att stänga av eller på produkterna via hemsidan. Systemet kompletterades även med möjligheten att öka övervakningen med hjälp av externa sensorer. Ett re-sultat av arbetet blev en prototyp som demonstrerar konceptet, ett annat resultat var flertalet möjliga förbättringar som kan göras för vidareutveckl-ing av konceptet. / Energy monitoring can lead to lowering energy consumption. This infor-mation would help the user to make decisions in regards to the power us-age. The measurements can also give the user the possibility to study the power quality to find bad loads and minimize the effects on the power grid. The choice of thesis was done to give the users the possibility to affect and monitor their environmental effect in a way that is otherwise not possible. A concept was developed that measure the voltage and current peak, the voltage and current RMS, power factor and the voltage waveform. The measurements are then sent to a server that is also containing a website. With the website the user can monitor their power usage and turn on or off the power consumers on the website. Added to the system is also the pos-sibility to add external sensors to increase the monitoring. The result of the project is a functioning concept to demonstrate. Another big result is the amount of improvements discovered to make it a really good base to con-tinue developing on.
