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 ...
Optimal location of TCSC and its use in congestion management
(2015)
Over the last two decades, electricity demand has increased substantially while the expansion of
generation and transmission network has been limited due to environmental and/or economic constraints of building new ...
Transient stability analysis of the kenyan power system with different wind generation technologies.
(2014)
Electrical power generation from wind is achieved using a number of generator technologies. The main technologies are the Squirrel Cage Induction Generators (SCIG) and Doubly Fed Induction Generators (DFIGs). In this paper, ...
Novel Modeling of a Fast DC Breaker for a VSC-HVDC Transmission System Protection
(2017-11)
The inability to quickly isolate the faulty sections of the direct current (DC) network damages the converters and the transmission system. Further delay in fault interruption can be escalated to the generation system thus ...
Energy Flow Strategy For A Small Scale Grid Tied Photovoltaic System Under Net Metering
(2019-10)
Grid connected PV systems continue to attract investors and electricity customers all over the world. Due to interconnection with the utility grid, the system can glean some benefits such as selling PV electricity surplus ...
Dynamic voltage stability analysis of the kenya power system using decision trees
(2014)
Dynamic Voltage stability analysis of any system is studied by considering load changes within the system and how voltage magnitudes at the load buses within the system are affected by the load changes. The analysis can ...
Wider range of tuning the proposed VSC-HVDC system for improved controller performance
(2016)
Tuning of the Voltage Source Converters, High Voltage Direct Current (VSC-HVDC)
controllers is a critical undertaking continuously carried out in power system operation to ensure system stability is kept under control ...
Modelling and loading limits for kenya coast power network using continuation power flow
(2016)
Shore to ship power connection for docked ship has recently been applied as one way of limiting pollution in ports.
This paper studies the effect that a shore to ship connection at the port of Mombasa would have on the ...
