1. 1. Local voltage control in a low voltage grid with high photovoltaic penetration

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Joakim Bakklund; [2024]
   Nyckelord :Technology and Engineering;

   Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

3. 2. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Wenhan Zhou; [2023]
   Nyckelord :Transuranus; AI; Nuclear Fuel Rods;

   Sammanfattning : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. LÄS MER

4. 3. Battery Storage as Grid Reinforcement for Peak Power Demands

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Jesper Hilleberg; [2023]
   Nyckelord :Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

   Sammanfattning : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

5. 4. Substation digitalization and fault isolation : A study of the influence of degree of digitalization to regulatory indicators in the power grid

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

   Författare :Ili Atalla; [2023]
   Nyckelord :;

   Sammanfattning : With changes in the energy sector, more demand is set on the power grid as electricity consumption is seen to increase and more decentralized renewable energy production is connecting to the grid. Svenska Kraftnät, electric system transmission operator in Sweden, describes the importance a more secure operation of the power system. LÄS MER

7. 5. Integrating dial-a-ride and ridesharing services in Curitiba’s Public Transport Network (RIT)

   Master-uppsats, KTH/Transportplanering

   Författare :Juan Manuel Lopez Vasquez; [2022]
   Nyckelord :;

   Sammanfattning : Demand Responsive Transport is regarded allegedly by many as the future of public transportation. Nevertheless, recent study shows that more than a half of DRT services provided by start-ups fail within their first 7 years of operation. LÄS MER
