11. Compensating the Changing Reactive Power in the Medium-Voltage Grid in Stockholm
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : A decline in inductive reactive power has been noted by several DNOs around Europe for the last decade. Why this is happening is unknown. One of the DNOs is the Swedish DNO Ellevio AB that has seen large decreases in demand of inductive reactive power from their primary substations. READ MORE

12. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.

13. Eliminating zero-missing phenomenon in long, high voltage, underground cables
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The maximum length of an high voltage underground cable (HV UGC) cable is oftenconstrained by the criterion that the cable cannot have more than 50% reactivepower compensation. If this limit is exceeded the current in the circuit breaker maynot have a zero crossing after energization, which is referred to as the zero missingphenomenon. READ MORE

14. Grid impact study of frequency regulation with EVs
University essay from Lunds universitet/Industriell elektroteknik och automationAbstract : The ongoing grid paradigm shift has resulted in synchronous generators currently being phased out. As the generators have been providing ancillary services, such as frequency control regulation, this means that new technologies to perform ancillary services need to be developed and evaluated.
