  1. 1. Techno-Economic Optimization and Control of Hybrid Energy Systems

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Louise Calmered; Tanja Nyberg; [2023]
    Nyckelord :Hybrid Energy Systems; Optimization; Control Techniques; Peak Shaving; Energy Arbitrage; Ancillary Services;

    Sammanfattning : The increasing demand for renewable energy sources to meet climate targets and reduce carbon emissions poses challenges to the power grid due to their intermittent nature. One potential solution to maintain grid stability is by implementing Hybrid Energy Systems (HESs) that incorporate a Battery Energy Storage System (BESS). LÄS MER

    Sammanfattning : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. LÄS MER

  5. 4. An Optimal Control Toolbox for MATLAB Based on CasADi

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Viktor Leek; [2016]
    Nyckelord :Optimal Control Direct Collocation Multiple Shooting Casadi Matlab Hybrid Vehicle;

    Sammanfattning : Many engineering problems are naturally posed as optimal control problems. It may involve moving between two points in the fastest possible way, or to put a satellite into orbit with minimum energy consumption. Many optimal control problems are too difficult to be solved analytically and therefore require the use of numerical methods. LÄS MER

  7. 5. Implementation of smooth interpolation for optimization

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

    Författare :Joakim Larsson; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Models of physical systems are often expressed as a system of mathematical expressions derived from first principles. However some of the relationships present in a model are more conveniently expressed as a table, i.e. for certain values of independent variables the values of dependent variables are known. LÄS MER
