Economic Dispatch of Oman’s Main Interconnected System in Presence of 500MW Solar PV Plant in Ibri

Currently, the main interconnected system (MIS) in Oman is using natural gas-based power plants to meet the increasing electricity demand. In 2018, the Oman Power and Water Procurement Company floated a tender for 500MW solar PV plant in Ibri. This manuscript investigates the impact of the proposed PV plant on MIS using an economic dispatch model. AC optimal power flow formulation (OPF) is used to solve the economic dispatch problem using MATPOWER power system simulation package. The network ac power flow model is verified using the data from MIS system operator.
