1. 16. Capacity forecasting for wind farms and connected power transformers

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Maximilian Hartmann; [2021]
   Nyckelord :Wind power; Forecasting; Dynamic Transformer Rating; Machine Learning; Vindkraft; prognostisering; dynamic transformer rating; machine learning;

   Sammanfattning : Transformers can be described as ’slumbering giants’ in the electric power system. This marks transformers to be big and expensive parts of equipment. Calling them slumbering refers to the unused capacity in many of them. LÄS MER

3. 17. Power-to-X-to-Power in Combined Cycle Power Plants : A Techno-Economic Feasibility Study

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Linus Engstam; [2021]
   Nyckelord :Power­to­X­to­power; Hydrogen; Ammonia; Combined cycle gas turbines; PEM electrolyzer; Technoeconomic analysis; Power­to­X­to­power; Vätgas; Ammoniak; Gasturbiner; PEM elektrolysator; Teknoekonomisk analys;

   Sammanfattning : To support the large­scale integration of renewables in electricity grids, power­to­X­to­power (P2X2P) systems have been proposed. These systems serve to increase the flexibility of thermal power plants while potentially providing both economic and environmental benefits by allowing power from the plant to be redirected into an electrolyzer and converted to a gaseous energy carrier.

4. 18. Evaluation of Net Transfer Capacity Reductions in the Nordic Power System

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Vageesh Chakrapani Manakari; [2020]
   Nyckelord :;

   Sammanfattning : The day-ahead dispatch of the Nordic power system is managed by the common electricity market Elspot, operated by Nordpool. Elspot is an area-based market and takes as input the net transfer capacity (NTC) between the price areas. LÄS MER

5. 19. Demand Side FLexibility and Bidding Strategies for Flexible Loads in Air-Conditioned Buildings

   Master-uppsats, KTH/Energiteknik

   Författare :Christian Utama; [2020]
   Nyckelord :;

   Sammanfattning : Demand-side flexibility (DSF) has been touted as a possible solution to thechallenges in power system operation arising as a result of the increasing intermittent renewables penetration and the emergence of electric vehicles (EVs). In Singapore, where around 24 to 60% of electricity demand in buildings couldbe attributed to heating, ventilation, and air conditioning (HVAC) purposes, air-conditioned building present a potentially major flexibility resource which could be used to provide DSF and help accommodate these challenges.

7. 20. Exploring Opportunities for Novel Electricity Trading Strategies within a Virtual Power Plant in the European Power Market : New Possibilities in Power Trading Due to the Increased Share of Variable Renewable Energy

   Master-uppsats, KTH/Energiteknik

   Författare :Lillie Ogden; [2020]
   Nyckelord :Electricity markets; power trading; variable renewable energy VRE ; trading strategies; virtual power plants VPP ; Elmarknader; krafthandel; variabel förnybar energi VRE ; handelsstrategier; virtuella kraftverk VPP ;

   Sammanfattning : This report explores the impacts of variable renewable energy (VRE) on power trading in the European wholesale electricity market. The intricate operation of a typical power exchange in Europe is accompanied by an equally complex balancing system. LÄS MER
