  1. 1. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Isabelle Löfgren; [2022]
    Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

  3. 2. Utilizing Genetic Algorithm and Machine Learning to Optimize a Control System in Generators : Using a PID controller to damp terminal voltage oscillations

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Fredrik Strand; [2022]
    Keywords : AVR; AI; data-driven; GA; SVM; GPR; SVR; Ziegler-Nichols; Z-N;

    Abstract : Hydropower is an important part of renewable power production in Sweden. The voltage stability of the already existing hydropower needs to be improved. One way to do this is by improving the control system that damp terminal voltage oscillations. READ MORE

  4. 3. Attenuation of bending waves in cross-laminated timber panels by using constrained damping layer

    University essay from Luleå tekniska universitet/Träteknik

    Author : Konrad Boeske; [2021]
    Keywords : Wood technology; damping; CLT; acoustic; low frequencies; AkuTimber;

    Abstract : Multi-storey wooden buildings become more and more popular. As the new housing solutions are more accessible, acoustical inconveniences of wooden buildings become actual as never before. Wood, thanks to its high stiffness and low mass, allows to erect buildings at impressive pace, albeit cannot damp low frequency noises efficiently. READ MORE

  5. 4. Tuning of Power System Stabilizers to Damp Out Power Oscillations

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

    Author : Joel Viil; Marcus Seisay; [2021]
    Keywords : Power System Stabilizer; Critical Generator; Small Signal Instability; Terminal Voltage; Field Voltage; Frequency;

    Abstract : With the rise of global sustainability energy initiatives,the implementation of renewable energy sources infuture electrical grids is increasing. Many of the renewableenergy sources are however intermittent, meaning they providevarying levels of power. READ MORE

  6. 5. Perennpaletten : en guide till pålitliga och långlivade perenner för fuktiga- och torra ståndorter

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Petra Dunér; Yrsa Lindberg; [2021]
    Keywords : ekologi; kompositionsförslag; kompositionsprinciper; naturalistisk växtgestaltning; perenner; växtgestaltning; ståndort; ståndortsanpassning; växtlista;

    Abstract : Hur kan man gå till väga för att skapa en ståndortanpassad och estetiskt tilltalande perennplantering? Den mycket fuktiga- eller mycket torra ståndorten kan upplevas utmanande att välja perenner till. Det kan även vara svårt att förutse hur kompositionen kommer utvecklas med tiden. READ MORE
