  2. 2. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

    Author : Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE

  3. 3. Integration of Distributed Renewable Energy and Energy Storages in Buildings

    Author : Yang Zhang; Jinyue Yan; Pietro Elia Campana; Anders Lundblad; Zhe Chen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; PV; Energy Storage; Operation; Optimization; Flexibility;

    Abstract : Photovoltaic (PV) is a distributed renewable energy technology that is suitable for integration in buildings. PV reduces the electricity demands as well as the greenhouse gas emissions of buildings. READ MORE

  4. 4. Building-related renewable electricity production with storage and energy-efficient buildings : Exploring barriers, drivers and quality assurance

    Author : Anna-Lena Lane; Mathias Cehlin; Thomas Olofsson; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency gap; energy performance gap; ByggaE; battery storage; barriers; drivers; Non-energy benefits NEB; questionnaire; quality assurance; PV; energieffektivisering; energieffektiva byggnader; kvalitetssäkring; byggprocessen; ByggaE; solel; batterilager; hinder; drivkrafter; enkätstudie; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : There is a need to reduce unsustainable use of fossil fuels. Increased usage of renewable energy by combined use of photovoltaic solar panels (PV) with battery storage is one way. Another way is to increase awareness of energy usage and reduce the energy performance gap by building energy-efficient buildings. READ MORE

  5. 5. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

    Author : Ingmar Leisse; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated Voltage Control; Distributed Generation; Electricity meter; PV; Wind Power; Distribution Network;

    Abstract : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. READ MORE
