The importance of interconnecting power systems lies in enhancing reliability, improving economic efficiency by optimizing power generation, and increasing stability by allowing for the sharing of resources and the integration of renewable energy. It helps in the exchange of power thus reducing the generation capacity, increasing the diversity factor, use of old power plants etc. The laboratory experiments listed provide hands-on experience in the analysis, control, and economic operation of interconnected power systems. The students understand the concepts like power flow analysis using various numerical methods (G-S, N-R, FDLF), economic load dispatch and unit commitment to minimize costs, and stability analysis to ensure the system can withstand disturbances. The sessions equip students with practical skills essential for managing and optimizing modern power grids.
