Creating additional network capacity on constrained medium voltage networks utilizing distributed generation (specifically PV technology) by Ramdhin, Avinash

“…Integrating distributed generation (DG) to medium voltage (MV) networks can improve or worsen the operating level of the network. However, linking this balance of network improvement to the amount of generation would improve the operating level. …”

Deriving a rate equation for the removal of manganese from solution using a gas mixture of sulphur dioxide and oxygen by Schulze-Messing, Jacobus

“…Due to the complicated and unknown reaction pathways for the oxidation of the manganese by the sulfur dioxide oxygen gas mixture, a need arose to describe the rate at which the manganese is precipitated from solution, not in terms of the exact species responsible for the oxidation, but rather as a function of the easily measurable operating parameters. …”

Primary refrigeration system commissioning based on a transcritical 2- stage R744 cycle by Teixeira, Daniella

“…To do this, the system is modelled in Simulink, and the performance of the model is verified by comparing the outputs of the model to that of the physical system while running with the same operating conditions. With the verified model, the transfer function of each control loop can be determined, and various control methods can be used to design the PI controllers. …”

Protection-based Distributed Generation Penetration Limits on MV feeders - Using Machine Learning by Nxumalo, Emmanuel

“…The cost function (one half mean squared error) for the models that predict ‘actual' relay operating times before DG penetration, at 35%, 65%, and 75% DG penetration converged to values below 120, 20, 15, and 15 seconds2 , respectively, within the first 100 iterations. …”
