Suitability of aggregation methods of induction motor models for transient stability load modeling of Kenya power transmission and distribution system
(2010)
Current trend indicate that there has been increase on power outage frequency. This has partly been as a result of unstable power system with very small security margin of operation. Therefore, this paper focusses on the ...
Voltage profile improvement using switched capacitors: case of single wire earth return distribution network
(2017)
Most rural areas in Africa are characterized by scattered villages with a very low demand in electricity. Due to improper planning and lack of knowledge on low cost technologies, the cost of extending the grid to supply ...
Dynamic voltage stability analysis of the kenya power system using vcpi stability index and artificial neural networks
(2014)
Dynamic voltage stability deals with the voltage levels and how they’re affected by either faults or load changes within the system. Voltage instability has long been suspected in the voltage collapse and islanding of power ...
Innovative Solar Photovoltaic and Thermoelectric Power Generator for a Recirculating Aquaculture System
(2020-09)
Solar Photovoltaic power generation is fast gaining popularity in Kenya. However, the effects of high cell temperatures continue to be a major hindrance to their efficiency especially for standalone systems. Water can be ...
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. ...
Optimal under-voltage load shedding using cuckoo search with levy flight algorithm for voltage stability improvement
(2015)
Voltage stability has become a serious threat of modern power system operation nowadays. To tackle this problem properly, load shedding is a countermeasure taken as a last resort. However, its consequences might result in ...
Suitability of aggregation methods of induction motor models for voltage stability analysis
(2012)
This paper focusses on the aggregation of multiple induction motors (IM) connected in parallel on the same bus into a single equivalent model using aggregation based on transformer equivalent circuit (method 1) and on ...
The use of RC4 Encryption to Provide Privacy for Smart Meters
(2018)
The electrical power grid is undergoing improvements and is being transformed to the Smart Grid. Smart Grid uses two-way power and information flow to better monitor, plan and control the electrical power grid. Advanced ...
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 ...
