1. 11. Anomaly Detection in District Heating using a Clustering based approach

   University essay from

   Author : Minh-Tung Nguyen; Metjan Baduni; [2021]
   Keywords : Anomaly Detection; Data Mining; Unsupervised Machine Learning; Clustering; DBSCAN; Time Series;

   Abstract : The global demand for energy has increased in recent years. In Northern Europe and North America, centralized production and distribution of heat energy is commonly regarded as District Heating (DH). Efficient delivery of heat in the DH system is crucial not only for the building dwellers but even for companies that supply such energy. READ MORE

   Abstract : The transition in the transport sector by the integration of battery electric vehicles (BEVs) brings a new challenge for the system operators to ensure the balance between supply and demand. The installation of new EV charges poses a surge in electricity demand in the coming years which jeopardizes the grid reliability and stability. READ MORE

4. 13. Digital district heating : Developing the heating value proposition with the help of digitalisation

   University essay from

   Author : Hanna Rangstedt Canholm; [2021]
   Keywords : ;

   Abstract : The aim of this thesis has been to identify key points in a district heating system where digitalisation can add higher value to the customer, and thereby contribute to a better district heating offer.  The purpose has been to examine how digitalisation of district heating processes could improve a Swedish district heating system and develop the district heating business in Sweden.

5. 14. Evaluation of Symmetrical Components Theory in Power Systems with Renewable Sources

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Daniil Danylov; [2021]
   Keywords : Symmetrical components theory; fault analysis; renewable sources; power electronics; PSCAD EMTDC; two bus system; inverter-based resources; line protection; nonlinear source.; Teori om symmetriska komponenter; felanalys; förnybara källor; kraftelektronik; PSCAD EMTDC; tvåbussystem; inverterbaserade resurser; linjeskydd; icke- linjär källa.;

   Abstract : Rapidly growing Inverter- Based Resources (IBR) have different fault properties compared to Synchronous Generators (SG). Therefore, it is necessary to study the fault behavior of systems that contain different types of IBR and compare it to the conventional system responses in order to understand what steps should be taken to adapt conventional protection settings for new types of sources.

6. 15. Analysis of Prerequisites for Connection of a Large-Scale Photovoltaic System to the Electric Power Grid

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Fanny Lilja; [2021]
   Keywords : solar energy; large-scale photovoltaic system; PV; Swedish power system; power output fluctuations; voltage quality; voltage variations; reactive power compensation; PSS E; solenergi; storskalig solcellsanläggning; PV; Sveriges kraftsystem; effekförändringar; spänningskvalitet; spänningsvariationer; reaktiv effektkompensering; PSS E;

   Abstract : The deployment of large-scale photovoltaic (PV) systems is rising in the Swedish power system, both in quantity and in system size. However, the intermittent characteristics of the PV production raises questions concerning the stability in the electric power grid, and power output fluctuations from the PV systems can lead to voltage quality issues.
