3. 2. Parallel Operation of Grid-Forming Power Inverters

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Alessia Camboni; [2023]
   Keywords : ;

   Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE

   Keywords : Current sensing; High bandwidth; Inverter; Hall-sensors; Strömavkänning; Hög bandbredd; Inverter; Hall-sensorer;

   Abstract : With the ongoing surge in electrification within the automotive industry, the demand for high-power inverters is steadily on the rise. Furthermore, these inverters are now expected to handle increased power loads while maintaining enhanced efficiency. READ MORE

5. 4. Harmonisk strömsimulering i inverterbaserade värmepumpar

   University essay from Umeå universitet/Institutionen för fysik

   Author : Alexander Magnusson; [2023]
   Keywords : Current harmonics; inverter-driven compressor; black box simulation;

   Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

6. 5. Techno-economic assessment of off-grid PV systems in Eritrean buildings : A case study about apartment buildings in Asmara

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Adonay Yosief; [2023]
   Keywords : Eritrea; PV; Asmara; Battery; Hydrogen; Homer Pro;

   Abstract : Eritrea is experiencing difficulties as a result of its low rate of electricity, together with its expanding population and the significance of green energy in today's world. Due to poor infrastructure and capacity, Asmara's electricity grid is well known for being unreliable, with frequent power outages and load shedding. READ MORE
