Interconnected power systems play a significant role in enhancing operational efficiency and improving economic performance in modern power generation, transmission, and distribution networks. The integration of multiple power generation sources through a unified grid allows electricity to be shared across regions, ensuring a more reliable and balanced supply-demand relationship. One of the primary advantages of interconnected systems is the optimization of generation resources. Different power plants operate with varying levels of efficiency depending on load conditions, fuel availability, and technological design. When systems are interconnected, high-efficiency plants can supply power during peak demand periods while less efficient or more expensive plants can be kept on standby, reducing overall generation cost. Another important benefit is improved load management. Electricity demand varies throughout the day and across geographical regions. Interconnected power systems allow operators to transfer surplus electricity from areas with low demand to regions experiencing high demand. This reduces the need for maintaining excessive reserve generation capacity in each isolated region. As a result, utilities can operate closer to optimal plant loading conditions, which enhances thermal efficiency and reduces fuel consumption in fossil-fuel-based generation units. Operational reliability is also significantly improved through interconnection. In isolated systems, any unexpected
