Assessing the economic feasibility of utility-scale electrical energy storage technologies for South Africa
(North-West University, 2018)Increased electrical production from renewable energy technologies, such as solar photovoltaic (PV) and wind plants, is at the forefront of the global energy transition to environmentally sustainable economic growth and ... -
Microgrid energy management system based on artificial intelligence
(North-West University (South Africa), 2019)Microgrids provide the opportunity to combine various distributed energy resources to supply a local load independently from, or in parallel with the national grid. This allows the load to utilise renewable energy as much ... -
Stability of acid-excess acid-base blend membranes in all-vanadium redox-flow batteries
(Elsevier, 2015)In this contribution the performance of two acid–base blend membranes in an all-vanadium redox-flow battery (VRFB) is studied. The first membrane is a nonfluorinated acid–base blend membrane composed of a sulfonated ... -
A techno-economic study of a pump storage hydropower system for ultra-deep level mines applied to Driefontein No. 9 Shaft
(North-West University, 2018)The energy required for mineral recovery is a major operational cost and strategic focus for the global mining sector. Power disruptions result in loss of production throughput and deceased profitability. Therefore, mines ...
