Abstract
SUMMARY
The paper presents techno-economic studies for connecting a 500MW Photovoltaic (PV) power plant to the Main Interconnected Transmission System (MITS) of Oman at Ibri. The objective is to justify the required capital expenditure on the basis of the submission of a full, complete and robust study report insuring the transmission system in Oman is planned, developed and operated in an efficient manner. Three connection options are proposed and compared considering cost, compliance with the transmission security standard, technical performance, deliverability, environmental conditions, flood risk assessment and safety.
The MITS models of 2020 and 2021 have been updated to include the simulation of the alternative connections of the 500MW PV power plant. The DIgSILENT PowerFactory professional software is used to perform system analyses for different cases. The solar PV technology and components are discussed. Steady-state analyses are presented; including power flow, 3-phase short-circuit, 1-phase short-circuit, (N-1) contingency and (N-M-1) contingency. Dynamic analyses are also performed and a sample of the results is presented to show frequency responses to the 500MW PV plant outage. The planning methodology leads to improving grid resiliency by considering the flood risk assessment and the transmission security standard.
