Energy Management and Control System for Laboratory Scale Microgrid Based Wind-PV-Battery
IEEE Transactions on Sustainable Energy, 2017Co-Authors: Adel Merabet, Khandker Tawfique Ahmed, Hussein Ibrahim, Rachid Beguenane, Amer M. Y. M. GhiasAbstract:—This paper proposes an energy management and con-trol system for Laboratory Scale microgrid based on hybrid energy resources such as wind, solar, and battery. Power converters and control algorithms have been used along with dedicated energy resources for the efficient operation of the microgrid. The control algorithms are developed to provide power compatibility and en-ergy management between different resources in the microgrid. It provides stable operation of the control in all microgrid sub-systems under various power generation and load conditions. The proposed microgrid, based on hybrid energy resources, operates in autonomous mode and has an open architecture platform for test-ing multiple different control configurations. A real-time control system has been used to operate and validate the hybrid resources in the microgrid experimentally. The proposed Laboratory Scale mi-crogrid can be used as a benchmark for future research in smart grid applications.

Laboratory-Scale Single Axis Solar Tracking System: Design and Implementation
International Journal of Power Electronics and Drive Systems (IJPEDS), 2016Co-Authors: Allan Soon Chan Roong, Shin Horng ChongAbstract:This paper presents the design and development of a Laboratory-Scale single axis solar tracking system. The chronological method was implemented into the system because it has high accuracy and can save more energy as compared to other types of solar tracking system. The Laboratory-Scale single axis solar tracking system can be used to identify the suitable and safe workspace for the installation of the actual solar tracking system plant. Besides, the validity of the Laboratory-Scale single axis solar tracking system was examined experimentally. The angle of rotation, per hour is preferable to be implemented into the designed Laboratory-Scale single axis sun tracking system due to the high performance ratio which is 0.83 and can save the energy up to 25% during sunny days.

Design and implementation of a Laboratory Scale single axis solar tracking system
2015Co-Authors: Chan Roong Soon, Shin Horng Chong, Chin Kim GanAbstract:The renewable solar energy can be produced by using the Photovoltaic (PV) panel which converts the solar energy to the electrical energy. Global warming can be reduced by using the solar energy to generate electricity. Therefore in this project, an active type single axis solar tracking system is designed and constructed. The solar tracking system can enhance the amount of solar energy harvest throughout the day as compared to the fixed solar panel. A Laboratory-Scale single axis solar tracking system is developed to have a better understanding on the working mechanism of the solar tracking system. By using the Laboratory-Scale system, the system becomes portable and convenient to be allocated at the suitable workplace for solar tracking process. Moreover, the Laboratory Scale solar tracking system can be easily controlled and programmed by the users such as angle of rotation of the solar panel and the direction of rotation. In this project, microcontroller is used as an integrated control unit and the plant is actuated by the DC geared motor. The validity of the Laboratory-Scale single axis solar tracking system was examined experimentally. The solar tracking system operates by rotating to the desired angle in every hour. The workspace of the solar tracking system is determined and identified. The solar tracking system workspace must be identified and examined carefully before the installation to prevent any accidents occurred during operation. This research is important for Faculty of Electrical Engineering of Universiti Teknikal Malaysia Melaka (UTeM) to identify the safety workspace for the solar tracking system due to the actual solar tracking system plant is still cannot be operated because of the limited workspace.

Bioreactor Scalability: Laboratory-Scale Bioreactor Design Influences Performance, Ecology, and Community Physiology in Expanded Granular Sludge Bed Bioreactors.
Frontiers in Microbiology, 2017Co-Authors: Stephanie Connelly, Seung Gu Shin, Robert J. Dillon, Umer Zeeshan Ijaz, Christopher Quince, William T. Sloan, Gavin CollinsAbstract:Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with Laboratory-Scale trials. However, it is rarely determined whether Laboratory-Scale results reflect full-Scale performance or microbial ecology. The Expanded Granular Sludge Bed (EGSB) bioreactor, which is a high-rate anaerobic digester configuration, was used as a model to address that knowledge gap in this study. Two Laboratory-Scale idealizations of the EGSB-a one-dimensional and a three- dimensional Scale-down of a full-Scale design-were built and operated in triplicate under near-identical conditions to a full-Scale EGSB. The Laboratory-Scale bioreactors were seeded using biomass obtained from the full-Scale bioreactor, and, spent water from the distillation of whisky from maize was applied as substrate at both Scales. Over 70 days, bioreactor performance, microbial ecology, and microbial community physiology were monitored at various depths in the sludge-beds using 16S rRNA gene sequencing (V4 region), specific methanogenic activity (SMA) assays, and a range of physical and chemical monitoring methods. SMA assays indicated dominance of the hydrogenotrophic pathway at full-Scale whilst a more balanced activity profile developed during the Laboratory-Scale trials. At each Scale, Methanobacterium was the dominant methanogenic genus present. Bioreactor performance overall was better at Laboratory-Scale than full-Scale. We observed that bioreactor design at Laboratory-Scale significantly influenced spatial distribution of microbial community physiology and taxonomy in the bioreactor sludge-bed, with 1-D bioreactor types promoting stratification of each. In the 1-D Laboratory bioreactors, increased abundance of Firmicutes was associated with both granule position in the sludge bed and increased activity against acetate and ethanol as substrates. We further observed that stratification in the sludge-bed in 1-D Laboratory-Scale bioreactors was associated with increased richness in the underlying microbial community at species (OTU) level and improved overall performance.
