Optimal hybrid power dispatch through smart solar power forecasting and battery storage integration (Elsevier, 2024-05)This study presents a strategy to optimize hybrid power system dispatch for commercial sectors in South Africa while utilizing the day-ahead method to forecast solar photovoltaic (PV) power. The approach utilizes numerical ...
-
(Elsevier, 2024-06)Several features of innovative grid technologies can be deployed to improve the overall performance of the power system environment. This can be seen from the generation to the consumption of energy. The two-way communication ...
-
(Oxford University Press, 2025-02)With the advent of modern radio interferometers, a significant influx in data is expected. This influx will render the manual inspection of samples infeasible and thus necessitates the development of automated approaches ...
-
(KeAi Communications, 2024-09)The fossil fuel powered mining truck fleets can contribute up to 80% of total emissions in open pit mines. This study investigates the optimal decarbonisation pathway for mining truck fleets. Notably, our proposed pathway ...
-
(Wiley, 2024-07)In this paper, DR programs are integrated with the unit commitment economic dispatch model for a single day to lower total operating costs for an insular microgrid. The proposed model takes into account the forecasting ...
-
(Elsevier, 2024-12)Smart grid can offer load sharing and utilize distributed energy resources to reduce energy consumption costs and potentially earn revenue through energy services. Information and communication technologies (ICT) in the ...
-
(Elsevier, 2024)Sticking valves tend to cause cycles in control systems used in industry, degrading product quality and yield. Many attempts have been made to alleviate the impact of stiction. Mechanical knockers are used with success ...
-
(Elsevier, 2024)The surge tank in a bulk tailings treatment plant aims to reject flow and density disturbances. However, for large disturbances, there may be an inversion in the gain between the water inflow and tank slurry density for ...
-
(Elsevier, 2024)Modern power systems comprise diverse nonlinear components, and an increasingly large number of low inertia renewable power sources necessitate the modernization of conventional power system security measures. Contingency ...
-
(Elsevier, 2024)Flotation optimisation strategies often trade off grade for recovery, without attempting to improve the mineralogical efficiency of the flotation process as part of the automatic control and optimisation strategy. Non-linear ...
-
(Elsevier, 2024)The plant-model ratio, developed to diagnose model-plant mismatch present in model-based controllers, inherits the same limitations from the frequency-based analysis that the method is based on. Nonetheless, the plant-model ...
-
(Elsevier, 2024)Although fuel gas systems represent a large part of industrial chemical processes, there has been limited literature on their modelling and control. The available literature typically neglects the effects of fuel gas ...

(University of Pretoria, 2017-12)Current steering has been proposed to increase place pitch resolution in cochlear implant (CI) users. Many studies have shown that a current steering effect can be achieved when simultaneous stimulation is used (Koch, ...
-
(University of Pretoria, 2016-02)English: The travelling wave encodes acoustic information by stimulating the auditory nerve fibres. Understanding the travelling wave and its process is important for the development of cochlear implants speech processors. ...
-
(University of Pretoria, 2016-07)A computational model of a single octopus cell as well as a population of octopus cells was developed. The models were used to investigate the ability of octopus cells to compensate for the travelling wave delay, remove ...
-
(Institute of Electrical and Electronics Engineers, 2025)Most radar systems do not consider the situation where the return is dominated by the polarisation orthogonal to the polarisation transmitted by the radar. A cross-polarisation jammer exploits this limitation by transmitting ...

The effect of temperature on household hourly electricity consumption : evidence from South Africa (Elsevier, 2025-03)Climate change is expected to negatively affect Africa, possibly leading to increased energy needs. However, meeting that need could prove problematic; more than a decade of load-shedding in South Africa is suggestive in ...
