Characterisation of a PEM electrolyser using the current interrupt method
(Elsevier, 2014)A method is proposed to model the electrochemical characteristics of a Proton Exchange Membrane (PEM) electrolyser. The electrochemical characteristics, which include the Ohmic, activation and concentration losses, are ... -
Energy-based visualisation of an axial-flow compressor system for the purposes of fault detection and diagnosis
(Elsevier, 2016)As the complexity of industrial systems increases, the necessity also increases for more reliable, robust and accurate Fault Detection and Diagnosis (FDD) techniques. This article proposes a methodology for the design of ... -
Genetic algorithm based PID tuning for optimal power control of a three-shaft Brayton cycle based power conversion unit
(Elsevier, 2012)This paper considers the development of a PID control strategy to optimally control the power output of a High Temperature Gas-cooled Reactor (HTGR) power plant. A specific type of HTGR called the Pebble Bed Modular Reactor ... -
Genetic fuzzy rule extraction for optimised sizing and control of hybrid renewable energy hydrogen systems
(Elsevier, 2020)A major challenge related to the design of a hybrid renewable energy hydrogen system is which energy sources to include and at what capacity, for regionally different potentials of renewable energy and hydrogen demand. In ... -
Hydrocyclone cut-size estimation using artificial neural networks
(Elsevier, 2016)The hydrocyclone is widely used throughout the mineral processing industry when working with slurries. It is either used for classifying, desliming or dewatering. Hydrocyclones are inexpensive, application-efficient and ... -
Improving dynamic microgrid modelling through the use of synchronised field data
(IEEE, 2020)Simulation during the design and operation of microgrids should include dynamic phenomena that would be a result of the unpredictable variation in renewable generation and loading. Detailed modelling of different components ... -
Microgrid energy management through levelized cost of energy metric
(IEEE, 2020)The abundance of solar energy in Africa provides the ideal opportunity to mitigate the concerns on price, reliability and voltage quality of electricity supply to end-users. Rooftop PV and local energy storage solutions ... -
Model predictive control of an active magnetic bearing suspended flywheel energy
(SAIEE, 2015)Flywheel Energy Storage (FES) is rapidly becoming an attractive enabling technology in power systems requiring energy storage. This is mainly due to the rapid advances made in Active Magnetic Bearing (AMB) technology. ... -
Sizing of renewable energy hydrogen systems
(IEEE, 2011)This paper explains the simulation and sizing optimization of renewable energy systems for hydrogen production. These systems are complex and challenging to size correctly due to the nonlinearities of the components and ...
