Under Voltage Load Shedding using Hybrid Metaheuristic Algorithms for Voltage Stability Enhancement: A Review
(2020)
Power blackouts are experienced globally, more so with increasing load demand and ageing infrastructure. The high failure rate of conventional and adaptive load shedding
techniques is prevalent during multiple contingencies. ...
E-Voting Challenges in Kenya
(2016-06)
Many developing countries have had disastrous presidential elections in recent years. In most of these cases, it was alleged that manual voting and vote-tallying took too long to produce the winning candidate, leading to ...
The dependency of bus voltage and frequency in load shedding
(2013)
Load shedding schemes proposed in literature so far use voltage and frequency parameters separately. The individual consideration of these indices may not be reliable or effective, and may even lead to the over load shedding ...
Power Quality Challenges and Mitigation Measures in Grid Integration of Wind Energy Conversion Systems
(IEEE, 2018)
Wind energy generation is a promising renewable energy source harvested through Wind Energy Conversion Systems (WECS). Since WECS have different characteristics
from conventional power plants, their integration into the ...
Adjusting Academic Library Services to Covid 19 Prevention Protocols
(2021-11)
The Covid 19 pandemic has presented challenges in the provision of library services in academic libraries. The pandemic has affected the mode of library operations and therefore librarians had to shift to virtual library ...
A Systematic Review On The Impact Of Educational Robots In Teaching Secondary School STEM Related Subjects
(2021-11)
Robots are interdisciplinary in nature. Research in Educational robotics in the education sector has grown tremendously. The robots have been used as teaching tools in STEM subjects. However, even though research interest ...
Short term voltage stability analysis of an aggregated industrial load
(2010)
Environmental constraints have limited expansion of transmission line networks. And with
Power systems being operated close to their security limits, the likelihood of voltage collapses
Occurring has increased [1]. In ...
Investigation of static voltage stability using a modified load flow algorithm and counter propagative artificial neural networks
(2010)
In conventional load flow studies, the active and reactive powers of all load buses are generally specified. Thus, by assuming a constant power load characteristic, the impact of the load in the system is over-emphasized ...
Disentangling farmers’ preferences and cost allocation among inputs for food security in Vihiga District, Kenya
(2011-03)
Vihiga, one of the poorest and densely populated districts in Kenya, is perpetually in food deficit. Poor welfare and a low resource base continue to curtail efforts to circumvent food insecurity among households in the ...
The Forgotten: An Information Ecosystem Assessment for People with Disabilities in South Sudan
(2023-03)
Decades of conflict in South Sudan pre-and post-independence in 2011, poverty and poor access to services have increased the rate of disability and rendered People with Disabilities more marginalised and excluded because ...
