A review of reactive compensation in the Main Interconnected System of Oman

Overvoltage is a concerning issue among Gulf Cooperation Council (GCC) nations during the winter light load period. This paper presented a review of the recent reactive compensation studies conducted by Oman Electricity Transmission Company (OETC) for the Main Interconnected System (MIS) of the Sultanate of Oman, regarding to its new 400 kV transmission systems. Discussions about challenges and possible solutions were outlined to highlight the unique operating nature of Middle East electrical infrastructures. Simulation results were presented to demonstrate the impact of 400 kV systems on the existing MIS grid. This paper serves as a contrasting example of voltage stability issues encountered by western utilities.
