  1. 1. Batteries charging into the future? Techno-economical analysis of BESS participation on the Swedish frequency regulation market using a mixed method approach

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Theodor Rosengren; [2023]
    Keywords : Battery Energy Storage Systems; Frequency Regulation; FCR-D; FFR; economic feasibility; Sweden; Technology and Engineering;

    Abstract : As the penetration of variable renewable energy is increasing, the demand for flexibility in the electrical grid is on the rise. One way in which flexibility is needed is to provide frequency regulation. If electricity consumption and production momentarily are unbalanced there needs to. READ MORE

  3. 2. Assessment of optimization control strategies for energy management

    University essay from KTH/Optimeringslära och systemteori

    Author : Bahar Kasbi; [2020]
    Keywords : Optimization; linear programming; applied linear optimization; sensitivity analysis; energy management; demand side management DSM ; heat pump scheduling; setpoint; Optimering; tillämpad linjär optimering; linjär programmering; känslighetsanalys; energihantering; värmepumpsplanering; börvärde;

    Abstract : With the increasing demand for renewable energy sources, new systems are being developed to sustain future infrastructure, accommodating these new energy sources. One of the proposed solutions is to incorporate distributed energy resources to different households in order to provide local energy demands effectively. READ MORE

  4. 3. Importance of atomic force microscopy settings for measuring the diameter of carbon nanotubes

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Anton Almén; [2019]
    Keywords : Carbon nanotubes CNTs ; Atomic force microscopy AFM ; diameter; height; tapping; frequency; phase; amplitude; setpoint; Kolnanorör; Atomkraftsmikroskopi AFM ; diameter; höjd; svängning; frekvens; fas; amplitud; börvärde;

    Abstract : Carbon nanotubes (CNTs) have gathered a lot of interest because of their extraordinary mechanical, electrical and thermal properties and have potential applications in a wide variety of areas such as material-reinforcement and nano-electronics. The properties of nanotubes are dependent on their diameter and methods for determining this using atomic force microscopy (AFM) in tapping mode assume that the measured height of the tubes represent the real diameter.

  5. 4. An experimental study of surface coatings to limit the impact of frosting

    University essay from KTH/Energiteknik

    Author : Carl Andersson; [2018]
    Keywords : ;

    Abstract : Heat pumps are commonly used as a way to efficiently meet heating demands. The efficiency and flexibility of Air-source heat pumps (ASHPs) have improved in recent years and is an attractive heating solution suitable for houses with lower heating demands, as it is inexpensive to purchase and install compared to other heating solutions.

  6. 5. Robust adaptive control of current in test equipment for lithium ion battery systems

    University essay from KTH/Optimeringslära och systemteori

    Author : Linus Sjövall; [2014]
    Keywords : ;

    Abstract : This thesis project have the purpose of investigating possibilities for a current control with respect to cell voltages in the testing procedures of large battery systems. The main goal is to design and implement a control that is not in need of considerable tuning, but still has stability and performance during all different conditions of testing. READ MORE
