Voltage stability and dynamic analysis of North-Eastern Indian power Grid

In a power system, reliability and stability are important issues to be evaluated under different contingency conditions. This paper proposes the important observations made during stability and reliability analysis on North-Eastern Indian Grid. The dynamic modelling of the system is also presented with study of dynamic response of the system under different disturbances. Finally, the voltage stability analysis of North-Eastern Indian grid under different contingency conditions is analysed based on the PV and QV analysis under base case and also under different contingency conditions. These simulations are performed in PSS@E software.
