  1. 1. Parallel Operation of Grid-Forming Power Inverters

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

    Författare :Alessia Camboni; [2023]
    Nyckelord :;

    Sammanfattning : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. LÄS MER

  3. 2. 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

  4. 3. Optimizing Resource Allocation in Kubernetes : A Hybrid Auto-Scaling Approach

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

    Författare :Brando Chiminelli; [2023]
    Nyckelord :Cloud computing; Microservices; Kubernetes; Container Orchestration; Auto-Scaling; Horizontal Pod Autoscaler HPA ; WorkloadPrediction; Time-Series Forecasting; Molntjänster; Mikrotjänster; Kubernetes; Containerorkestrering; Automatisk Skalning; Horizontal Pod Autoscaler HPA ; Förutsägelse avArbetsbelastning; Prognoser för Tidsserier;

    Sammanfattning : This thesis focuses on addressing the challenges of resource management in cloud environments, specifically in the context of running resource-optimized applications on Kubernetes. The scale and growth of cloud services, coupled with the dynamic nature of workloads, make it difficult to efficiently manage resources and control costs. LÄS MER

  5. 4. Predictive Scaling for Microservices-Based Systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Simon Pettersson; [2023]
    Nyckelord :scalability; load prediction; cloud; cloud computing;

    Sammanfattning : This thesis aims to explore the use of a predictive scaling algorithm to scale a microservices-based system according to a predicted system load. A scalable system along with a predictive scaling algorithm is developed and tested by applying a periodic load to the system. LÄS MER

  7. 5. Comparing Virtual Threads and Reactive Webflux in Spring : A Comparative Performance Analysis of Concurrency Solutions in Spring

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Carl Haneklint; Yo Han Joo; [2023]
    Nyckelord :Virtual threads; Spring Boot; Reactive WebFlux; Java; Concurrency; Virtual threads; Spring Boot; Reactive WebFlux; Java; Concurrency;

    Sammanfattning : To develop a high performant web service in Java, Reactive WebFlux has previously been utilized as the only alternative. With the introduction of virtual threads in Java 19, it has been considered that it would be an alternative to the current provided option. LÄS MER
