1. Evaluation of key performance indices for frequency quality : A method for evaluating frequency stability in the Nordic power system
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Nordic power system is in a changing phase, with more power electronic interfaced connections, and HVDC connections to other synchronous areas, which impacts the frequency quality. This is a challenge for the transmission system operator of Sweden, Svenska Kraftnät, who, with the other Nordic transmission system operators, is responsible for the physical balancing of the Nordic power system.

4. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. LÄS MER
5. Cumulative energy assessment of Ligna Energy organic battery : From its extraction to its end-of-life thermal conversion
Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för kemiteknikSammanfattning : With an increasing share of intermittent electricity production in the energy system, there is an increased need for energy storage. Because of electrochemical batteries’ ability of modularization, fast response and flexibility, grid connected energy storage will enable load balance and dispatching stored energy to optimize grid operations.
