  1. 26. Modelling interactions between distributed energy technologies and the centralised electricity supply system

    Författare :Joel Goop; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems modelling; variable renewables; power systems; distributed generation; demand response; electricity storage;

    Sammanfattning : Renewable electricity generators, such as solar photovoltaics (PVs), and variation management technologies, such as battery storage and demand response (DR) systems, can be deployed in a distributed fashion, which can benefit the overall system. Such distributed energy technologies interact with and influence the centralised generation and transmission systems. LÄS MER

    Sammanfattning : Background. Police work is a stressful occupation with frequent exposure to traumatic events and psychological strain from work might increase the risk of burnout. This thesis focuses on patrolling police officers (PPO), who work most of their time in the community and have daily contact with the public. LÄS MER

  4. 28. Does the psychosocial school environment matter for health? : a study of pupils in Swedish compulsory school from a gender perspective

    Författare :Katja Gillander Gådin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; psychosocial school environment; demand; control; social support; classmate problems; rowdiness; ill health; health behavior; power; gender;

    Sammanfattning : Despite the fast-growing evidence of the importance of the psychosocial work environment for the health of adults there is a lack of research about the possible health effects of the work environment among pupils, that is, their school environment. This is especially true for the psychosocial aspects of the pupils' school situation. LÄS MER

  5. 29. Increasing the hosting capacity of distributed energy resources using storage and communication

    Författare :Nicholas Etherden; Sami Repo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Energy Generation; Energy Storage; Hosting Capacity; Curtailment; Demand Response; Dynamic Line Rating; Power System Communication; Smart Grid; Förnyelsebara energikällor; Energilagring; Acceptansgräns; Kommunikation i kraftsystem; Smarta elnät; Energy Engineering; Energiteknik; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : The use of electricity from Distributed Energy Resources like wind and solar powerwill impact the performance of the electricity network and this sets a limit to theamount of such renewables that can be connected. Investment in energy storage andcommunication technologies enables more renewables by operating the networkcloser to its limits. LÄS MER
