The electrical voltage is one of the important parameters, which must be considered to assure the safety of any power system. The secure, safe and reliable operation of Nuclear power plants (NPPs) needs many studies for the interaction between the NPP and Electrical Grid. This paper presents an analysis to show the mutual interface between electrical grid and NPP under different scenarios of abnormalities on both the electrical grid and NPP. The pressurized water reactor (PWR) NPP mathematical models are presented in MATLAB/ Simulink. The responses of NPP key parameters under step increase and decrease in power demand were studied and presented to evaluate and assess the load following ability of the NPP. Then the weighted least squares (WLS) state estimation method is used to study the IEEE 30-bus system response for a sudden shut down and generation loss of NPP by 50%. The IEEE 30 bus system voltage profile is presented and analysed. This study can contribute to understand the performance of both NPP and electrical grid under different scenarios of expected disturbances and this can offer certain guidance for the engineering practice.
