5. 4. Dispatch Optimization of the TES.POD Cluster using Mixed-Integer Linear Programming Models

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Ivar Wikander; [2023]
   Nyckelord :Optimization; Electricity dispatch; Mixed Integer Linear Programming; MILP; Solar PV; Microgrid; Energy Transition; Optimering; Solkraft; Linjär programmering; Elnät;

   Sammanfattning : With increasing shares of variable renewable energy sources in the power mix, the need for energy storage solutions is projected to increase as well. Storage can in such combined systems help mitigate the issues with relying on intermittent sources by time-shifting the supply and smoothing out frequency fluctuations, to name some examples.

7. 5. Analysis of Electricity Usage Time Series with K-means Clustering

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Göran Iliev; [2022]
   Nyckelord :electricty usage; office; residential; time series; clustering;

   Sammanfattning : As the amount of collected and analysed data for electricity usage from buildings is increasing it becomes an important component in energy efficiency efforts. A huge problem when developing algorithms fordetection of anomalous electricity usage series is the lack of data setswith annotated normal usage series for training and evaluation purposes. LÄS MER
