  1. 1. Reliability and Cost-Benefit Analysis of the Battery Energy Storage System

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

    Författare :Dita Anggraini; [2023]
    Nyckelord :Battery Energy Storage System; Cost-Benefit Analysis; Prediction Methods; Reliability Analysis; Batterienergilagringssystem; Förutsägelsemetoder; Kostnads-nyttoanalys; Tillförlitlighetsanalys;

    Sammanfattning : The battery energy storage system (BESS) is crucial for the energy transition and decarbonisation of the energy sector. However, reliability assessment and capital cost challenges can hinder their widespread deployment. LÄS MER

  3. 2. Analysis of Electricity Usage Time Series with K-means Clustering

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Göran Iliev; [2022]
    Nyckelord :electricty usage; office; residential; time series; clustering;

    Sammanfattning : As the amount of collected and analysed data for electricity usage from buildings is increasing it becomes an important component in energy efficiency efforts. A huge problem when developing algorithms fordetection of anomalous electricity usage series is the lack of data setswith annotated normal usage series for training and evaluation purposes. LÄS MER

  4. 3. Component importance indices and failure prevention using outage data in distribution systems

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

    Författare :Sindhu Kanya Nalini Ramakrishna; [2020]
    Nyckelord :outage; fault; distribution system; component importance indices; outage prediction.;

    Sammanfattning : Interruptions in power supply are inevitable due to faults in power system distribution network. These interruptions are not only expensive for the customers but also for the distribution system operator in the form of penalties. Increase in system redundancy or the use of component-specific sensors can help in reduction of interruptions. LÄS MER

  5. 4. Exploration of implicit weights in composite indicators : The case of resilience assessment of countries’ electricity supply

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :David Lindén; [2018]
    Nyckelord :Composite indicators; Index; Weights; Aggregation; Implicit Weights; Correlation; Energy Security; Resilience; Electricity Supply; Sensitivity Analysis; Nonlinear Regression Analysis; Optimisation; Representativeness;

    Sammanfattning : Composite indicators, also called indices, are widely used synthetic measures for ranking and benchmarking alternatives across complex concepts. The aim of constructing a composite indicator is, among other things, to simplify and condense the information of a plurality of underlying indicators. LÄS MER

  7. 5. Credit Spread Changes in the Euro Area - An Empirical Study of the Relationship Between Interest Rates and Credit Spreads in the Euro-denominated Corporate Bond Market

    Kandidat-uppsats,

    Författare :Hampus Johansson; Rickard Rehnberg; [2017-07-07]
    Nyckelord :;

    Sammanfattning : The behaviour of credit spreads is of importance for a wide array of stakeholders. We test the relationship between changes in risk-free interest rates and credit spreads in European bond market by running OLS regressions using weekly European market data for investment grade and non-investment grade bond indices.
