  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. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Sammanfattning : Access to energy is an important part in the development of most countries and societies, linked to both social and economic growth. Nevertheless, 70% of the population in sub-Saharan Africa does not have access to electricity, which brings consequences to several of these areas. LÄS MER

  5. 4. Rapid expansion of roof mounted PV systems in commercial facilities - How can they be insured?

    Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Erik Lindén; [2023]
    Nyckelord :PV system fires; PV component failures; PV regulations; future PV regulations; PV risk assessment; PV risk evaluation; PV insurance price; Technology and Engineering;

    Sammanfattning : PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. LÄS MER

  7. 5. Mathematical Model for Inverter Power Output in PV Parks

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Shashidhar Suragimath; [2023]
    Nyckelord :Mathematical Modelling; PV System; Energy Systems; Solar Inverter; Forecasting;

    Sammanfattning : Solar photovoltaic (PV) parks have proliferated all over the world as a result of the growing demand for electricity, and especially electricity from renewables. As these parks become larger and complex, it becomes increasingly important to develop accurate and efficient mathematical models that can be used to predict their performance and optimize their design.
