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 ...
Under Voltage Load Shedding on a Modified IEEE 14-Bus System Using Hybrid ABC-PSO Algorithm for Voltage Stability Enhancement
(Elsevier, 2021-08)
Voltage collapse tends to occur due to the voltage instability created during large faults. As a last resort, under-voltage load shedding (UVLS) is performed after all the available power operation and control mechanisms ...
Impact of integrating large-scale DFIG-based wind energy conversion system on the voltage stability of weak national grids: A case study of the Nigerian power grid
(Elsevier, 2021-11)
This paper investigates the impact of integrating large-scale Doubly-Fed Induction Generator (DFIG)-based wind energy conversion system (WECS) on the voltage stability of the 52-bus, 330 kV Nigerian power grid. Indices ...
Modeling and Energy Management Strategy in a Grid Connected Solar PV System
(Scientific & Academic Publishing, 2021-09)
Electric power is substantially an important resource in the modern world. With the increase in demand for electric energy, there is a need to search for alternative energy sources because conventional resources are being ...
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 ...
