Corporate social responsibility practices of banks in Bangladesh: a structuration theory perspective
No full textThe aim of this paper is to illuminate the role of the socio-economic, cultural and religious context in shaping corporate social responsibility (CSR) practices of banks in Bangladesh. We utilise content analysis of annual reports and websites of banks to identify CSR activities in healthcare, education and financial inclusion sectors. We use structuration theory (ST) to explain how interactions between bank managers (as agents) with the social structures (institutions and government) shape CSR practices. Our findings show that banks’ engagement in CSR activities is embedded in the social fabric of Bangladesh and not a result of the Global Reporting Initiative (GRI). We also note that Islamic banks focus their CSR activities on social justice, while other banks target education and other humanitarian issues. We contribute to the literature on the determinants of CSR by revealing the rationalizations of different actors in the production and reproduction of CSR practices in Bangladesh, an insight we attribute to ST. We conclude that Islamic beliefs influenced managers to mitigate poverty through CSR investments

Harmonic-Based Overcurrent Scheme for Optimal Protection Coordination of Islanded Microgrids
No full textA Master of Science thesis in Electrical Engineering by Abdelrahman M. A. Kamal Abdelaziz entitled, “Harmonic-Based Overcurrent Scheme for Optimal Protection Coordination of Islanded Microgrids”, submitted in December 2022. Thesis advisor is Dr. Mostafa Shaaban and thesis co-advisor is Dr. Maher Azzouz. Soft copy is available (Thesis, Completion Certificate, Approval Signatures, and AUS Archives Consent Form).Protection of microgrids dominated by inverter-based distributed generators (IBDGs) is challenging as these IBDGs are characterized by their low contribution to fault currents. Therefore, their fault currents can be confused with the normal operating current, which imposes a major challenge for overcurrent protection relays to distinguish faulty conditions. Furthermore, the change in the microgrid's topology due to the intensive use of IBDGs imposes a major concern. The IBDG has an interfacing LC filter with relatively high impedance compared to the microgrid’s lines. This affects the sequence networks; hence, the three-phase fault is not the most severe. In this thesis, harmonic voltage generation methodology is deployed. Performing the protection coordination in a new harmonic layer formed during faults helps to avoid the problem of distinguishing faulty conditions. It is proposed to include the symmetrical as well as asymmetrical faults in the optimal protection coordination (OPC) problem formulation. The inclusion of asymmetrical faults ensures a more reliable operation of the proposed overcurrent protection scheme, as relying only on symmetrical faults can be deceptive. A comparison between current levels for different fault types and different transformer connections is presented to highlight the importance of asymmetrical faults inclusion in the OPC as well as provide evidence of symmetrical-based approaches failure. After modifying the OPC by including asymmetrical faults, the results are compared to a newly proposed fault type multi settings (MS)-based OPC. The OPC problem is formulated as a non-linear programming (NLP) that is developed in GAMS software. The results are validated using a test system which is a section of a Canadian distribution system, as well as the IEEE-33 bus system. Results confirm the proposed MS-based method’s ability to enhance the relays’ total operation time. 14% and 38% reduction in the total operating time are achieved for the 9 bus and 33 bus respectively. Several case studies are conducted to demonstrate the effectiveness of the proposed methodology in providing OPC considering symmetrical and asymmetrical faults with high fault resistances besides evaluating the proposed protection scheme capability to maintain precise coordination in case of expanding the IBDGs capacities.College of EngineeringDepartment of Electrical EngineeringMaster of Science in Electrical Engineering (MSEE
