“…But only few [5]- [6], [14]- [18] studied the impact of different abnormal phenomena such as sudden load addition or load rejection, generation outage, combination of both load addition and generation outage, large motor starting, different types of faults inside island. As the islanded systems are weaker than integrated system; even a small disturbance causes significant effects on islanding operation which leads to fluctuation in voltage, current, frequency and power factor making power quality poor.…”

Electrical quantities such as frequency, voltage, current are being fluctuated due to abnormalities in power system. Most of the abnormalities cause fluctuation in system frequency and sometimes extreme abnormalities lead to system blackout. To protect the system from complete blackout planned and proper islanding plays a very important role even in case of extreme abnormalities. Islanding operation not only helps stabilizing a faulted system but also supports power supplies to critical and important loads, in extreme emergency. But the islanding systems are weaker than integrated system so the stability of islands is the prime concern when an integrated system is disintegrated. In this paper different impacts on a load rich island have been studied and a frequency based auto load shedding scheme has been developed for sudden load addition, generation outage and combined effect of both to the island. The developed scheme has been applied to Khulna-Barisal Island to validate the effectiveness of the developed technique. Various types of abnormalities to the test system have been simulated and for the simulation purpose CYME PSAF (Power System Analysis Framework) has been used.

“…These sources include wind turbines, photovoltaic arrays, fuel cells, tidal turbines etc. The overall impact would be a reduced need for large infrastructure construction or upgrades, reduction of losses on the distribution and transmission lines, and reduction of cost to the residential consumer [2][3]. In the case of a system outage, the island of New Providence can act as an "islanding system" for improving service reliability and supplying uninterrupted power to critical loads during this time with utilization of renewable energy sources.…”

Caribbean islands such as the Bahamas, Grenada and St. Lucia are affected yearly by seasonal hurricanes and tropical storms which can lead to blackouts and voltage variations of the power system. The Bahamas in particular consists of 16 isolated island grids which inhabits a population of 300,000. Diesel generators are employed to provide electricity for each island, but with increasing oil prices, and maintenance cost the Bahamas Electricity Corporations faces a huge loss on electricity generation in the millions of dollars each year. To decrease this loss and to improve the power quality of the system, distributed generation systems are being sought after. This paper investigates the effects of utilizing renewable energy sources on the island of New Providence, Bahamas and analyzing various load shedding schemes on the system in the instance of a disturbance due to a natural disaster. A report of the New Providence Transmission system was used in modeling the 132kV grid system using the Electrical Transient Analyzer Program 12.0 (ETAP) environment to perform a load flow and transient analysis for reducing power losses in the transmission system and improving reliability of the Bahamian distribution system.
