  1. 1. Heat Storage in Buildings : Achieving thermal peak shaving through indoor temperature flexibility

    University essay from Mälardalens universitet/Framtidens energi

    Author : Mathilda Cederblad; August Dahlberg; [2022]
    Keywords : Building thermal model; Short-term thermal storage; Grey-box model; District heating;

    Abstract : Buildings are currently controlled in a sub optimal way, using a WC controller that is dependent only on the external temperature. A rich amount of real-time data from installed sensors is available within the buildings and the network and can be used to counteract this. READ MORE

  2. 2. SELF-SUFFICIENT OFF-GRID ENERGY SYSTEM FOR A ROWHOUSE USING PHOTOVOLTAIC PANELS COMBINED WITH HYDROGEN SYSTEM : Master thesis in energy system

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Mahamed Maxamhud; Arkam Shanshal; [2020]
    Keywords : Off-grid; PV panels; hydrogen system; battery system; thermal storage tank; heat pump; life cycle cost; electrical load; thermal load; OPTI-CE;

    Abstract : It is known that Sweden is categorised by being one of the regions that experience low solar radiation because it is located in the northern hemisphere that has a low potential of solar radiation during the colder seasons. The government of Sweden aim to promote a more sustainable future by applying more renewable initiative in the energy sector. READ MORE

  3. 3. Towards Flexible Power Generation Short-term Optimization of a Combined Cycle Power Plant Integrated with an Inlet Air Conditioning Unit

    University essay from KTH/Energiteknik

    Author : Weimar Mantilla Gutierrez; [2019]
    Keywords : Combined cycle gas turbine; Power augmentation; Flexibility; Inlet air conditioning; Thermal energy storage; Heat pump; Mixed-integer linear programming MILP; kombikraftverk; kraftförbättring; flexibilitet; inluftsbehandling; termisk energilagring; värmepump; linjär programmering; MILP;

    Abstract : Combined cycle gas turbine power plants (CCGT), as part of the electricity generation fleet, are required to improve their flexibility to help balance the power system under new scenarios with high shares of variable renewable sources. Among the different possibilities to enhance the power plant performance, an inlet air conditioning unit offers the benefit of power augmentation and “minimum environmental load” reduction by controlling the gas turbine intake temperature using cold thermal energy storage and a heat pump.

  4. 4. Thermal storage solutions for a building in a 4th generation district heating system : Development of a dynamic building model in Modelica

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Rickard Eriksson; Pontus Andersson; [2018]
    Keywords : Thermal storage; 4th generation district heating system; dynamic simulation; thermal mass storage; building model; thermal dynamics; building inertia; Värmelagring; 4:e generationens fjärrvärmesystem; dynamisk simulering; byggnadsmodell; termisk masslagring; termisk byggnadströghet;

    Abstract : The world is constantly striving towards a more sustainable living, where every part of contribution is greatly appreciated. When it comes to heating of buildings, district heating is often the main source of heat. During specific times, peak demands are created by the tenants who are demanding a lot of heat at the same time. READ MORE

  5. 5. Stochastic Investment in Power System Flexibility:A Benders Decomposition Approach

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Fernando Garcia Mariño; [2016]
    Keywords : ;

    Abstract : The e_cient use of the available assets is the goal of the liberalized electricity market. Nowadays, the development of new technologies of renewable production results in a signi_cant increase in the total installed capacity of this type of generation in the power system. READ MORE
