Abstract
SUMMARY
Â
The paper presents the technical studies for grid connection of the planned new generating plant in Al Duqm Industrial area in the southern part of Oman. The maximum capacity of of the Al Duqm Independent Power Plant IPP) is 1200 MW and it is planned to be connected to the Main Interconnected Transmission System (MITS) by 2023. The main challenge of this connection is the location of this generation plant where it is located approximately 490 km from the nearest possible connection of the MITS, which therefore has major technical, deliverable and economic implications. Two connection viable options are proposed and compared in terms of cost, net present value, technical performance, deliverability, environmental conditions, flood risk assessment safety and compliance with the security standard. This paper describes the technical and economic analyses conducted to optimise the design of the required transmission line series compensation which will lead to fully dispatching the 1200 MW from Al Duqm IPP over a long distance to the MITS. Simulation studies using DIgSILENT software are conducted to verify the effectiveness of the selected connation option. The studies include steady-state and transient analyses.
