1. 1. Line Distance Protection in Power Grids with Variable Renewable Energy Sources : An Investigation on Time Domain Distance Protection via Parameter Estimation

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

   Author : Ludvig Ringaby; [2023]
   Keywords : Distance protection; Power system protection; Time domain distance protection; Differential Equation Algorithm; Variable renewable energy; IBR; Distansskydd; Skyddssystem i elkraftsystem; Tidsdomän distansskydd; Differentialekvationsalgoritm; Variabel förnybar energi;

   Abstract : Variable renewable energy sources typically connect to the power grid through power electronic interfaces. Increased use of such sources can cause issues for conventional distance protection. READ MORE

3. 2. Configurable, scalable single-ended sense amplifier with additional auxiliary blocks for low-power two-port memories in advanced FinFET technologies

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Limitha Subbaiah Kumar Nangaru; [2022]
   Keywords : CMOS Complementary Metal Oxide Semiconductors ; DRC Design Rule Check ; Process Corners; FinFET Fin Field Effect Transistor ; IC Integrated Circuit ; LVS Layout Versus Schematic ; Monte Carlo; Nominal Voltage; PDK Process Design Kit ; Power Delay Product; Read Bit Line; Read Word Line; SoC System on Chip ; SRAM Static Random Access Memory ; Threshold Voltage; Technology and Engineering;

   Abstract : System on Chip (SoC) designs contain a variety of Intellectual Property (IP) cores, including digital signal processing blocks, media and graphics processing units, as well as processing core units that employ multiple-port memories to enhance performance and bandwidth. These memories allow parallel read/write operations from the same memory blocks from different ports. READ MORE

4. 3. Operation planning for power grids with high instalment of dynamically rated components in liberalised electricity markets

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

   Author : Frida Lundquist; [2022]
   Keywords : Multi-interval real-time markets; Dynamic line rating; Optimal Power Flow; Renewable resources; Ramp-rate; Time inconsistency;

   Abstract : The power grid is a complex system that requires detailed planning and operation of the power sources. As renewable resources are increasing their share of the power mix, there are new criterion and aspects to take into account. Renewable resources such as wind and solar power are intermittent and challenge the planning and operation further. READ MORE

5. 4. A novel way of building high-speed railways with optimised overhead wire lengths

   University essay from KTH/Matematisk statistik

   Author : Axel Backlund; [2021]
   Keywords : High-speed railways; dynamic programming; optimization; Höghastighetsjärnväg; dynamisk programmering; optimering;

   Abstract : High-speed railways provide fast, comfortable and environmentally friendly transportation for passengers. However, they are fraught with high investment costs that decrease the willingness of governments to construct new lines. READ MORE

6. 5. Transient Voltage Distribution in Bushing

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

   Author : Md Nazmus Shakib Khan; [2020]
   Keywords : Coaxial cable; Overvoltage transient; Power transformer bushing; Skin effect; Koaxialkabel; överspänningsövergående; transformatorgenomföring; hudeffekt;

   Abstract : An electrical bushing is one of the most important elements in a power transformer. Steep front surges such as transient impulse voltage from lightning strikes is an inevitable electromagnetic transient mostly happening in power transmission and distribution system. The bushing might lead to be degraded due to such kind of surge. READ MORE
