    • Modelling and Simulation Approaches for Local Energy Community Integrated Distribution Networks 

      Rana, Rubi; Berg, Kjersti; Degefa, Merkebu Zenebe; Löschenbrand, Markus (Peer reviewed; Journal article, 2022)
      Due to the absence of studies of local energy communities (LECs) where the grid is represented, it is very difficult to infer implications of increased LEC integration for the distribution grid as well as for the wider ...

    • Modelling Approaches for Local Energy Community 

      Rana, Rubi; Degefa, Merkebu Zenebe; Berg, Kjersti; Löschenbrand, Markus (SINTEF Rapport;, Research report, 2021)
      Due to the absence of well documented experiences from implementations of Local Energy Communities (LECs), it is very difficult to infer implications of increased LEC integrations for the distribution network as well as ...

    • Post-primary voltage control using optimal power flow for loss minimization within web-of-cells concept 

      Degefa, Merkebu Zenebe; D'Arco, Salvatore; Morch, Andrei Z; Mavrogenou, Kyriaki; Hatziargyriou, Nikos; Merino, Julia (Chapter; Peer reviewed, 2017)
      This paper presents the decentralized Post-Primary Voltage Control (PPVC) scheme which is introduced within the Web-of-Cells (WoC) concept in the ELECTRA IRP project. The PPVC improves the traditionally known secondary and ...

    • Power hardware-in-the-loop validation of post-primary voltage control scheme 

      Degefa, Merkebu Zenebe; D'Arco, Salvatore; Morch, Andrei Z; Endegnanew, Atsede Gualu (Chapter; Peer reviewed, 2017)
      The concept and experimental validation process of the Web-of-Cells (WoC) based Post-Primary Voltage Control (PPVC) developed in EU FP7 project ELECTRA IRP is presented in this paper. The main objective of PPVC is to provide ...

    • Reference minigrids and minigrids controllers for rural India 

      Perumalla, Chandrasekhar; Degefa, Merkebu Zenebe; Klemets, Jonatan Ralf Axel (Research report, 2021)

    • Review of Grid Interconnection Requirements and Synchronization Controllers for Dispersed Minigrids 

      Degefa, Merkebu Zenebe; Klemets, Jonatan Ralf Axel; D'Arco, Salvatore; Sekhar, P.C.; Gupta, Amit (Chapter; Peer reviewed, 2021)
      As of 2019, the world population without electricity access is estimated to 770 million with most of these communities residing in sub-Saharan Africa. Nevertheless, between 2000 and 2019 the Indian population with electricity ...

    • Seasonally variant deployment of Electric battery Storage systems in active distribution networks 

      Degefa, Merkebu Zenebe; Sæle, Hanne; Foosnæs, Jan Andor; Thorshaug, Eirik (CIRED Conference Proceedings;2017, Chapter; Peer reviewed, 2017)
      Due to the aging of network infrastructure, the increasing load demand in distribution networks together with the increased installation of PVs (Photovoltaic) in the MV and LV network, there is a need for network reinforcement. ...

    • Simulation-based validation of smart grids – Status quo and future research trends 

      Steinbrink, Cornelius; Lehnhoff, Sebastian; Rohjans, Sebastian; Strasser, Thomas I.; Widl, Edmund; Moyo, Cyndi; Lauss, Georg F.; Lehfuss, Felix; Faschang, Mario; Palensky, Peter P.; van der Meer, Arjen A.; Heussen, Kai; Gehrke, Oliver; Guillo-Sansano, E.; Syed, Mazzheruddin Hussain; Emhemed, Abdullah; Brandl, Ron; Nguyen, Van Hoa; Khavari, Ali M.; Tran, Quoc Tuan; Kotsampopoulos, Panos C.; Hatziargyriou, Nikos; Akroud, Nabil; Rikos, Evangelos J.; Degefa, Merkebu Zenebe (Journal article; Peer reviewed, 2017)
      Smart grid systems are characterized by high complexity due to interactions between a traditional passive network and active power electronic components, coupled using communication links. Additionally, automation and ...
