1. Hosting Capacity Methods Considering Complementarity between Solar and Wind Power : A Case Study on a Swedish Regional Grid
Master-uppsats, Linköpings universitet/EnergisystemSammanfattning : The demand for electrical power is growing due to factors such as population growth, urbanisation, and the transition from fossil fuels to renewable energy sources. To be able to keep up with the changes in electricity demand, the Swedish power grid must connect more renewable power generation, but also increase its transmission capacity. LÄS MER
2. Framtidens lågspänningsnät : Analys av utmaningar och lösningar med ny teknik i nätet
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : With an ever growing demand for electricity, it is tough to know which challenges will be the most pressing and which solutions will be appropriate to implement in different cases. This thesis utilizes simulations of three low voltage grids to see which part of the grid is most vulnerable, to which extent grid reinforcement is needed to solve voltage and load problems, and what amount of demand flexibility services would be an adequate substitute to grid reinforcement.

3. Analys av påverkan från ökad mikroproduktion och installation av laddare för elfordon i lågspänningsnät
Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskapSammanfattning : In Sweden, the number of rechargeable cars increases for every year. It is common to charge at home, for example because there is no need to wait for the vehicle to be fully charged.Charging at home takes place with low effects for longer time periods. The installation of micro production with photovoltaic systems is also increasing. LÄS MER
4. Design of a Sustainable Energy System for a Community Center in rural Mozambique : A Minor Field Study in Mozambique
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Access to energy is an important part in the development of most countries and societies, linked to both social and economic growth. Nevertheless, 70% of the population in sub-Saharan Africa does not have access to electricity, which brings consequences to several of these areas. LÄS MER
5. Dimensionering av lågspänningsonråde : med hänsyn till utbyggnad av mikroproduktion och elbilsladdning
Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : Denna studie undersöker effekterna av storskalig mikroproduktion och laddning av elbilar på detsvenska elnätet. Den ökande populariteten av mikroproduktion, som individuell solkraftproduktion,och det växande intresset för elbilar kan ha betydande påverkan på det befintliga elnätet. LÄS MER
