    • The Combined Contribution of Bus Voltage and Frequency of a High Voltage AC in Load Shedding 

      Mwaniki, Charles; Maina, Christopher Muriithi; Abungu, Nicodemus (2015)
      Load shedding schemes proposed in literature so far use voltage and frequency parameters separately. The individual consideration of these indices may not be reliable or effective, and may even lead to the over load shedding ...

    • Optimal Sizing and Analysis of a Hybrid Energy System for a Community Microgrid in Nigeria 

      Nasakhale, Okhuegbe Samauel; Mwaniki, Charles; Akorede, Mudathir Funsho (Medwell Journals, 2019)
      This study focuses on determining the optimal size of each component of a hybrid energy system to meet the energy demand of Itele community in Nigeria at minimum Net Present Cost (NPC). The hybrid energy system consists ...

    • Satellite early identification through LED observations: First in-orbit results from WildTrackCube-SIMBA 

      Piergentili, Fabrizio; Marzioli, Paolo; Frezza, Lorenzo; Curianò, Federico; Zarcone, Gaetano; Mariani, Lorenzo; Amadio, Diego; Gianfermo, Andrea; Picci, Niccolò; Bedetti, Emanuele; Hossein, Shariar Hadji; Kabutha, Daniel Kiarie; Celesti, Paola; Rossetti, Matteo; Cimino, Lorenzo; Bucciarelli, Mascia; Seitzer, Patrick; Cutler, James; Mwaniki, Charles; Toninelli, Murizio; Jahjah, Munzer; Santoni, Fabio (Science Direct, 2022-04)
      Autonomous illumination payloads on-board small satellites, i.e. LED (LightEmitting Diode) boards on CubeSats, can be tracked by ground-based telescopes for optical identification, orbit determination and attitude determination. ...

    • Voltage Stability Improvement Using the 21st Century Power Transformer 

      Mwaniki, Charles; Abungu, Nicodemus; Wekesa, Cyrus (Innovative Systems Design and Engineering, 2012)
      The 21st Century Power Transformer is produced by combining modern high voltage cross-linked polyethylene (XLPE) cable technology with conventional transformer. The technique of solid insulation is adopted in the new dry ...
