1. 1. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes

   University essay from Linköpings universitet/Informationskodning

   Author : Martin Clason; [2023]
   Keywords : shot noise; quantum random number generator; photodiode; transimpedance amplifier; skottbrus; kvantslumptalsgenerator; fotodiod; transimpedansförstärkare;

   Abstract : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. READ MORE

3. 2. Application of PSS to Improve the Stability of a Power System With a High Penetration of Renewable Energy

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

   Author : Sixten Norelius; Ylva Persson; [2023]
   Keywords : ;

   Abstract : Unlike traditional power generation composed of synchronous generators, renewable energy in theform of solar and wind power does not add inertia to power systems. Therefore, as increasedproportions of renewable energy are added, the dynamics of the power system will be affected. READ MORE

4. 3. The Optimal Bidding Strategy of a Wind-Biogas-Hydrogen Hybrid System

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Xudong Liu; [2022]
   Keywords : bidding strategy; wind; biogas; hydrogen; hybrid system; two-price settlement;

   Abstract : The growing penetration of variable renewable energy has brought all-round challenges to the current power system, no matter for the grid infrastructure, market design or the power producers. The positive and negative externalities caused by the market participators are to be finer priced and a significant amount of flexibility is to be added to the system, in order to counter these problems and facilitate energy transition.

5. 4. Excitation system – simulation, tuning and evaluation

   University essay from Uppsala universitet/Elektricitetslära

   Author : Philip von Heideken; [2021]
   Keywords : ;

   Abstract : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.

6. 5. Modeling and comparative analysis of different grid-forming converter control concepts for very low inertia systems

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Martin Westman; Ellen Nordén; [2020]
   Keywords : Grid Forming; Renewables;

   Abstract : As renewable power from DC sources are constantly increasing their power generation share compared to the high inertia generators that provide robustness to the grid, the overall stability of the grid decreases. Grid forming converter could be the solution to this problem. READ MORE
