1. 1. Grid impact study of frequency regulation with EVs

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Emma Blomgren; [2018]
   Keywords : Electric vehicles EVs ; grid impact; ancillary services; frequency regulation; FCR-N; vehicle-to-grid V2G ; voltage; reactive power; load profile; Technology and Engineering;

   Abstract : 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.

3. 2. Analysis of a load frequency control implementation in Swedish run-of-river hydropower stations

   University essay from Elektricitetslära

   Author : Andreas Westberg; [2012]
   Keywords : Hydropower; power system; frequency controlled reserves; load frequency control; Matlab Simulink;

   Abstract : The total amount of frequency deviations have during the last decade increased exponentially in the Nordic synchronous power system. The transmission system operators have therefore decided to implement load frequency control as a new automatic control system to stem these frequency deviations. READ MORE

4. 3. ELECTRICAL MODELING OF A THERMAL POWER STATION

   University essay from KTH/Elektriska energisystem

   Author : Reinhard Kaisinger; [2011]
   Keywords : ;

   Abstract : Physical systems are becoming more heterogeneous. Different engineering domainsare interacting more and more. Therefore, it is desirable to have modeling tools that allow multi-domain modeling. In thermal power plants, three engineering domains are of particular relevance: a) thermodynamics, b) mechanics and c) electrical engineering. READ MORE
