1. 1. Centralised MPC for Long-term Voltage Stability Control of Power System

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Johan Hallberg; [2023]
   Nyckelord :Voltage stability; Model predictive control; Tap-changing transformer; Capacitor bank; Spänningsstabilitet; Model prediktiv reglering; Lindningskopplare; Kondensatorbank;

   Sammanfattning : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. LÄS MER

3. 2. Wait Time Estimation in Distributed Multitenant Systems : Using Queuing Theory

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Zainab Alsaadi; [2022]
   Nyckelord :Queue management; Estimated Wait Time; Position in Queue; Multi-tenant architecture; Queuing models; Queuing theory; The theory of mass service; Köhantering; Estimerad väntetid; Plats i kö; Fleranvändarsystem; Betjäningssystem; Köteori; Teorin för masservice;

   Sammanfattning : Queueing theory is widely used in practical queuing applications. It can be applied for specific models of queuing systems, especially the ones that follow the Markovian property. Its purpose is to predict system behaviour in order to be used for performance optimization. LÄS MER

4. 3. Tillsammans för ett hållbart arbetsliv : Ett förslag på en utvärderingsmodell som mäter individens utveckling mot ett hållbart arbetslivEn studie av iManagements arbete

   Kandidat-uppsats, Uppsala universitet/Industriell teknik

   Författare :Ximena Samuelsson-Allendes; Charlott Lundberg; [2022]
   Nyckelord :effectiveness; sustainable working life; total quality management; Språngbrädan; effektivitet; hållbart arbetsliv; offensiv kvalitetsutveckling; Språngbrädan;

   Sammanfattning : The purpose of the study is to present a proposal of an evaluation model that can be used by organizations to measure individuals' development towards a sustainable working life. The study is supported by studies of the organization iManagement, which trains individuals in selfleadership on behalf of both national and international organizations. LÄS MER

5. 4. PV self-consumption: Regression models and data visualization

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Martos Tóth; [2022]
   Nyckelord :Self-Consumption; photovoltaics; battery; machine learning; solar energy; random forest; k-nearest neighbor; multi-layer perceptron; lasso regression; ridge regression; linear regression; Egenanvändning; photovoltaics; batteri; maskininlärning; solenergi; random forest; k-nearest neighbors; multi-layer perceptron; lasso regression; ridge regression; linjär regression;

   Sammanfattning : In Sweden the installed capacity of the residential PV systems is increasing every year. The lack of feed-in-tariff-scheme makes the techno-economic optimization of the PV systems mainly based on the self-consumption. The calculation of this parameter involves hourly building loads and hourly PV generation. LÄS MER
