title: The Modelling and Design of Solid State Transformer for Smart Energy

description: This research presents the modelling and design of a solid-state transformer (SST) for smart energy, by scrutinizing and analyzing the problems associated with Low-Frequency Transformers (LFT) and presenting the SST as a model and solution in the smart energy system.The behaviour of the SST in dynamic conditions that is suitable to a smart energy system was carried out, through the analysis of the SST vital components (converters) and their parameters which should be designed first. This is done by an erudite mathematical analysis, culminating in various equations representing their behaviour, function, and their ratings. The required voltage, current and power rating of each component is represented by corresponding equations that unveils the impedance matching requirement, ensures that maximum power is transferred between connecting components of the SST in the smart energy system. The components of the SST analyzed include the Cascaded Hybrid Bridge (CHB) converter which converts AC to DC and connects to the Dual Active Bridge (DAB) through a DC link capacitor. The DAB is another converter that uses a high frequency transformer situated in between the DC - DC and transforms DC/AC to AC/DC, while ensuring galvanic isolation in the SST high voltage side and low voltage side, and it links to the Three Phase Four Leg (3P4L) converter through a DC link capacitor. The 3P4L DC/AC converter links the SST to the load or grid. The equations, mathematical functions, and algorithms developed in this study will help in the design of converters DC links, and the combinations of these components culminating in the design of the SST.To assist in retrieving the converters filter parameters, the algorithms are written in simple but engineering and mathematical problem-solving centered methodology, for easy implementation in the various programming language. The efficiency analyses of the SST are performed using the POET framework. The verification, modelling and design are done using MATLAB Simulink. Hence, the potential use or applications of SST as a component of a power grid, modern house, and smart energy is unveiled.The research ethical reference number: 2021FEBEREC-STD-109

title: Deacetylation of Mannosylerythritol Lipids in Hydrophobic Natural Deep Eutectic Solvents - Datafile.xlsx

description: These are the research data and calculations supplemented to the paper: Deacetylation of Mannosylerythritol Lipids in Hydrophobic Natural Deep Eutectic Solvents. Mannosylerythritol lipids (MELs) are a promising group of biosurfactants due to their high fermentation yield, self- assembly and biological activity. During fermentation by Pseudozyma aphidis, a mixture of MELs with different levels of acylation is formed, of which the fully deacetylated form is the most valuable. In order to reduce the environmental impact of deacetylation, an enzymatic process using natural deep eutectic solvents (NADES) has been developed. We tested the deacetylation of a purified MELs mixture with immobilized Candida antarctica lipase B enzyme and 2-ethylhexanol as co-substrate in 140 h reactions with different NADES. We identified hydrophobic NADES systems with similar yields and kinetics as in pure 2-ethylhexanol solvent. Our results indicate that deacetylation of MELs mixtures in NADES as a solvent is possible with yields comparable to pure co-substrate and that hydrophobic NADES without carboxylic acid compounds facilitate the reaction to the greatest extent.

title: African sustainable microgrid development with solar PV and energy storage

description: This research project developed a microgrid using solar PV to electrify remote communities in the DRC. Given that solar energy is intermittent and is not available during night-time when the electricity demand is usually at its peak, the microgrid was configured with a Battery Energy Storage System (BESS) to ensure an uninterrupted power supply. Also given that the BESS is a high-cost component, the microgrid considered the introduction of a biogas generator, to reduce the BESS architecture which subsequently reduces the cost of the implementation and operation of the system. The microgrid configuration was modeled and simulated using HOMER Pro to determine its techno-economic viability for the electrification of the community compared to the extension of the existing networks.Ethic reference number: 2021FEREC-STD-05

title: Techno economic analysis of a low cost biogas fed combined heat and power system for African villages.

description: The increasing depletion of fossil fuels and the imperative of environmental sustainability have compelled the adoption of renewable energy sources (RES). Particularly, the utilization of renewable resources is crucial in African countries where challenges persist in accessing electricity and modern cooking fuels. Conventional electricity generation systems have proven inadequate to meet the growing energy demands within African villages due to the scarcity of fossil fuels. Consequently, this study examines the viability of alternative energy sources, focusing on the conversion of biomass into biogas through anaerobic digestion technology. Many African nations possess abundant biomass resources, making them potential feedstock for biogas production through commercial biogas plants. However, challenges such as startup finances and equipment shortages have hindered the full exploitation of these resources. This research addresses the feasibility of using anaerobic digestion to convert household and poultry waste from rural areas in Limpopo and Western Cape province, South Africa, into biogas for cooking, and lighting. The study employs two simulation models, one for the anaerobic digestion process and another for the subsequent power generation. Anaerobic digestion, a well-established technology for organic waste treatment, proves promising in this context. Research outcomes indicate that anaerobic digestion of kitchen and animal waste is a viable method for biogas production. Food waste amounting to 668 kg and 467.5 kg from Madombidzha village and Walladecene area produced a biogas volume of about 522.3 m<sup>3</sup> and 365.2 m<sup>3</sup>, respectively while poultry waste amounting to 418 kg from Madombidzha village produced a volume of about 209 m<sup>3</sup>. The results reveal that the more the waste the more biogas volume production. Employing the HOMER Pro hybrid microgrid system for electric power generation, the study demonstrates that the biomass from these rural areas can also be used in a biogas generator to generate electrical power. The estimated electric power production from the biogas generator in Madombidzha village and Wallacedene area amounts to about 109,508 kWh/year and 199,000 kWh/year, respectively. This investigation underscores the potential of anaerobic digestion as a sustainable energy solution, paving the way for the wider adoption of biogas technology in rural African communities.Ethic reference number: 2021FEBEREC-STD-023
